A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling and manufactured according to API specification 7K.

The advantages of the drilling mud pump include the ability to move high-solids-content fluids laden with abrasives, the ability to pump large particles, ease of operation and maintenance, reliability, and the ability to operate over a wide range of pressures and flow rates by changing the diameter of pump liners and pistons.

The fluid end includes cylinders (module), valve assembly, cylinder liners, piston assembly, suction manifold, discharge manifold, piston rod, pulsation dampener assembly, etc.

As an important equipment for oilfield drilling operation, a drilling mud pump delivers circulating high-pressure drilling fluid or drilling mud to the bottom of the oil well, flushes the bottom of the well, breaks the rock, cools, lubricates and clean the drill bit, and carries the cuttings back to the ground.

The drilling mud is also used to suspend and carry out drill cuttings from the drill bits as it is brought in and out of the hole. This ensures that the drill bit does not clog and overheat, and makes the entire drilling operation smooth and safe.

Rotational power is supplied to the mud pump through an external power source like a diesel engine or electric motor. The power end of the mud pump converts the rotational energy through a crankshaft to a reciprocating motion of pistons.

The pistons move back and forth in mud pump liners, exerting a force on the cylinder chamber. During the retraction of the piston, valves open to allow the fluid to be drawn into the cylinder. Once the piston has fully retracted, it is pushed back into the cylinder.

At this time the intake valves are closed and the exhaust valves open, allowing the piston to force the fluid out of the cylinder under pressure. Once the piston reaches its maximum depth into the cylinder, the exhaust valves close and the process repeats.

For Fluid End: piston rod clamp, piston rod, piston assembly, cylinder cover, liner, liner flange, wear plate, cylinder, valve assembly, valve cover, valve guide, flashboard assy., cylinder cover flange, cylinder head, gaskets, studs, nuts, seal rings, pulsation dampener, bladder, discharge manifold, suction manifold, etc.

The crank gear and connecting rods drive a rotary movement that is transferred by the motor transmission. The pressure is produced by the piston in the cylinder due to which the mud is sucked. Following the operation, the suction valve is closed when it moves to left. As the pressure increase in the pipeline, the valve is forced to open and mud is released.

In accordance with the operating liquid displacer type being incorporated, the pumps are subdivided into piston units and plunger-type units. The liquid discharge uniformity is independent of head. The pumping plants are used actively for the processes with the liquids containing solid inclusions in high amounts. Incorporating the self-suction function in piston unit, the liquid is sucked and discharged twice in mud pumps during the single shaft turn, making themselves the double-action pumps whereas, the mud plunger pumps are single-action pumps where the liquid is sucked and discharged only once during a shaft turn.

The single direct-action three-piston pumps prove to be better than other types of drilling. These pumps demonstrate much more uniformity in mud delivery, lesser weight, and easy mounting when compared with two-cylinder units.

Depending on the number of cylinders, the pumping plants are classified into the following categories, single-cylinder, double-cylinder, three-cylinder and multi-cylinder pumping plants. These cylinders may be vertical or horizontal. Comparatively, the multi-cylinder pumping plants will cost higher but don’t feature any significant advantages other than the single-cylinder.

When drilling, there might occur the necessity of mud pumping out- and flushing-out, so there are various types of pumps available for such operations which are required to be installed on drilling rigs.

Sucker-rod pumps: In sucker-rod pumps, the pumpjack is a driver. This pump is installed at the bottom of the well. The reciprocating movements of the pumpjack are converted into liquid flow by the pump, which results in delivery of liquid on the surface. These pumps move oil with various admixtures demonstrating high level of capacity.

Screw pumps:The screw pumps are small-sized and are generally used to deliver mud into a centrifuge. These pumps have the rotor and stator as the major structural components and the material used to manufacture these components suit right for smooth pumping of liquids with solid inclusions and high level of viscosity. The pumped liquid flows with stable pressure, shaft slowly and the flow is free of vortexes. These pumps comparatively require minimum service.

Well pumps: These pumps are submerged into wells. The ground part of the plant is a transformer substation equipped for start and adjustment. The pump has a vertical structure, with a fixed cylinder and single-action. A plunger and valve are moving parts. The pumped liquid may contain water content of up to 99% at the temperature as high as 130ºC.

All the mud pumps have few general advantages that include the capability to process liquids and substances with high level of viscosity and with admixtures. Also, enabling the smooth flow of substances, free of pulsations or suspensions mixing are counted under the major advantages of incorporating mud pumps. The pumps have high suction power and small weight, easing out the transportation and installation at remote oil fields. They are highly reliable and also affordable.

There are various types of mud pumps available for different purposes. So, it is important to incorporate the right one for your purpose. A Professional help in getting the right mud pump would be a good and safe option.

Drilling for oil associated gas exploration is a concerned and sophisticated operation requiring specialized machinery to accomplish. Rig mud pumps area unit one among the element items of machinery required for a winning drilling operation. Waters International provides rig mud pumps and alternative specialized boring instrumentation for the oil and gas exploration trade.

A rig mud pump is employed is employed to flow into lubricant or lubricant into the bore hole to assist cool, lubricate and clean the drill head because it bores into the bottom. The lubricants additionally accustomed suspend and perform drill cuttings from the drill head because it is brought in and out of the opening. This ensures that the drill doesn’t clog and overheat, and makes the whole drilling operation swish and safe.

Drilling rig mud pump is typically mutual kind pumps that essentially work by drawing fluid into a chamber or cylinder by the action of a piston, plunger or diaphragm, then pushing it resolute the required direction through the utilization of unidirectional or check valves,leading to the periodical flow of the liquid in one direction. Ganging multiple pumps along will increase pump potency and provides a power tool liquid flow for higher performance.

The action of the pump is employed to prolong the lubricant from the borehole, that is then filtered and cleared of impurities before being sent back in to cool down and lubricate the drill head land take away a lot of drill cuttings. A failing pump can cause a non continuous flow of the lubricator, which might cause the drill head to overheat or jam from cuttings and probably even break. This may end in injury to the drilling instrumentality, and doubtless cause injury to the drilling crew close to the drill rig.

There are three types of mud pumps, depending on the type of client and the size they want. For general, mud pumps, there are three basic types of mud pumps, depending on the type of client and budget. The piston pump is another compressed mud pump, which is a pushed electric compressor mud pumps and by compressed air.

Electric mud pumps are largely divided into three categories, among them the electric mud pumps and the semi-trash mud pumps. The piston inflated mud pumps are also classified in terms of the type of mud pumps, among them are electric mud pumps and semi-trash mud pumps. In addition, the piston inflates mud and mud pumps will be inflated by the piston, which is inflated mud pumps.

The drilling industry has roots dating back to the Han Dynasty in China. Improvements in rig power and equipment design have allowed for many advances in the way crude oil and natural gas are extracted from the ground. Diesel/electric oil drilling rigs can now drill wells more than 4 miles in depth. Drilling fluid, also called drilling mud, is used to help transfer the dirt or drill cuttings from the action of the drilling bit back to the surface for disposal. Drill cuttings can vary in shape and size depending on the formation or design of the drill bit used in the process.

Watch the video below to see how the EDDY Pump outperforms traditional pumps when it comes to high solids and high viscosity materials commonly found on oil rigs.

Solids control equipment including shakers, hydro-cyclones, and centrifuges are utilized to clean the drill cuttings from the drilling fluid, which then allows it to be reused and recirculated. The circuit includes the mixing of the drilling fluid in the rig tanks.

The drilling fluid is prepared to control fluid loss to the formation by the addition of chemicals or mineral agents. Commercial barite or other weighting agents are added to control the hydrostatic pressure exuded on the bottom of the well which controls formation pressures preventing fluid or gas intrusion into the wellbore.

The fluid is charged into high-pressure mud pumps which pump the drilling mud down the drill string and out through the bit nozzles cleaning the hole and lubricating the drill bit so the bit can cut efficiently through the formation. The bit is cooled by the fluid and moves up the space between the pipe and the hole which is called the annulus. The fluid imparts a thin, tough layer on the inside of the hole to protect against fluid loss which can cause differential sticking.

The fluid rises through the blowout preventers and down the flowline to the shale shakers. Shale shakers are equipped with fine screens that separate drill cutting particles as fine as 50-74 microns. Table salt is around 100 microns, so these are fine cuttings that are deposited into the half-round or cuttings catch tank. The drilling fluid is further cleaned with the hydro-cyclones and centrifuges and is pumped back to the mixing area of the mud tanks where the process repeats.

The drill cuttings contain a layer of drilling fluid on the surface of the cuttings. As the size of the drill cuttings gets smaller the surface area expands exponentially which can cause rheological property problems with the fluid. The fluid will dehydrate and may become too thick or viscous to pump so solids control and dilution are important to the entire drilling process.

One of the most expensive and troubling issues with drilling operations is the handling, processing, and circulation of drilling mud along with disposing of the unwanted drill cuttings. The drilling cuttings deposited in the half round tank and are typically removed with an excavator that must move the contents of the waste bin or roll-off box. The excavators are usually rented for this duty and the equipment charges can range from $200-300/day. Add in the cost for the day and night manpower and the real cost for a single excavator can be as much as $1800/day.

Using the excavator method explained above, the unloading of 50 barrels of drill cuttings from the half round can take as long as two hours. This task is mostly performed by the solids control technicians. The prime duty for the solids control technicians is to maintain the solids control equipment in good working order. This involves maintenance for the equipment, screen monitoring and changing, centrifuge adjustments, and retort testing to prepare a daily operational summary of the solids control program.

Operating the excavator takes the technician away from these tasks and can lead to poorly performing equipment. Additionally, the excavator has the potential for abuse as some solids control technicians use the climate-controlled cab as a break area or refuge from the elements. Many times, these guys are found asleep on the job.

One solids control company reported the idle time for the excavator can be more than 8 hours for a 24-hour period with 8 hours of operation and 8 hours of shut down time. Fuel and time lost can cause an economic drag on rig operations. And lastly, there have been several accidents on each rig causing a potential for injury, loss of production, and lost revenue as the excavator must be repaired.

Offshore drilling rigs follow a similar process in which the mud is loaded into empty drums and held on the oil platform. When a certain number of filled drums is met, the drums are then loaded onto barges or vessels which take the drilling mud to the shore to unload and dispose of.

Oil field drilling operations produce a tremendous volume of drill cuttings that need both removal and management. In most cases, the site managers also need to separate the cuttings from the drilling fluids so they can reuse the fluids. Storing the cuttings provides a free source of stable fill material for finished wells, while other companies choose to send them off to specialty landfills. Regardless of the final destination or use for the cuttings, drilling and dredging operations must have the right high solids slurry pumps to move them for transport, storage, or on-site processing. Exploring the differences in the various drilling fluids, cutting complications, and processing options will reveal why the EDDY Pump is the best fit for the job.

The Eddy Pump is designed to move slurry with solid content as high as 70-80 % depending on the material. This is an ideal application for pumping drill cuttings. Drill cuttings from the primary shakers are typically 50% solids and 50% liquids. The Eddy Pump moves these fluids efficiently and because of the large volute chamber and the design of the geometric rotor, there is very little wear on the pump, ensuring long life and greatly reduced maintenance cost for the lifetime of the pump.

plumbed to sweep the bottom of the collection tank and the pump is recessed into a sump allowing for a relatively clean tank when the solids are removed. The Eddy Pump is sized to load a roll-off box in 10-12 minutes. The benefit is cuttings handling is quicker, easier, safer, and allows for pre-planning loading where the labor of the solids control technician is not monopolized by loading cuttings. Here, in the below image, we’re loading 4 waste roll-off bins which will allow the safe removal of cuttings without fear of the half-round catch tank running over.

Mud cleaning systems such as mud shaker pumps and bentonite slurry pumps move the material over screens and through dryers and centrifuges to retrieve even the finest bits of stone and silt. However, the pump operators must still get the raw slurry to the drill cuttings treatment area with a power main pump. Slurry pumps designed around the power of an Eddy current offer the best performance for transferring cuttings throughout a treatment system.

Options vary depending on whether the company plans to handle drill cuttings treatment on-site or transport the materials to a remote landfill or processing facility. If the plan is to deposit the cuttings in a landfill or a long-term storage container, it’s best to invest in a pump capable of depositing the material directly into transport vehicles. Most dredging operations rely on multiple expensive vacuum trucks, secondary pumps, and extra pieces of equipment.

Using an EDDY Pump will allow a project to eliminate the need for excavators/operators to load drill cuttings, substantially lowering both labor and heavy equipment costs. The EDDY Pump also allows a company to eliminate vacuum trucks once used for cleaning the mud system for displacing fluids. Since the pump transfers muds of all types at constant pressure and velocity throughout a system of practically any size, there’s little need for extra equipment for manual transfer or clean up on the dredge site.

The EDDY Pump can fill up a truck in only 10 minutes (compared to an hour) by using a mechanical means such as an excavator. For this reason, most companies can afford one piece of equipment that can replace half a dozen other units.

This application for the Eddy Pump has the potential to revolutionize the drilling industry. Moving the excavator out of the “back yard” (the area behind the rig from the living quarters) will make cuttings handling a breeze. Trucking can be easier scheduled during daylight hours saving on overtime and incidences of fatigued driving. Rig-site forklifts can move the roll-off boxes out of the staging area and into the pump loading area. The operator can save money on excavators rental, damages, and keep the technician operating the solids control equipment.

The EDDY Pump is ideal for drilling mud pump applications and can be connected directly onto the drilling rigs to pump the drilling mud at distances over a mile for disposal. This eliminates the need for costly vacuum trucks and also the manpower needed to mechanically move the drilling mud. The reasons why the EDDY Pump is capable of moving the drilling mud is due to the hydrodynamic principle that the pump creates, which is similar to the EDDY current of a tornado. This tornado motion allows for the higher viscosity and specific gravity pumping ability. This along with the large tolerance between the volute and the rotor allows for large objects like rock cuttings to pass through the pump without obstruction. The large tolerance of the EDDY Pump also enables the pump to last many times longer than centrifugal pumps without the need for extended downtime or replacement parts. The EDDY Pump is the lowest total life cycle pump on the market.

When choosing a size and type of mud pump for your drilling project, there are several factors to consider. These would include not only cost and size of pump that best fits your drilling rig, but also the diameter, depth and hole conditions you are drilling through. I know that this sounds like a lot to consider, but if you are set up the right way before the job starts, you will thank me later.

Recommended practice is to maintain a minimum of 100 to 150 feet per minute of uphole velocity for drill cuttings. Larger diameter wells for irrigation, agriculture or municipalities may violate this rule, because it may not be economically feasible to pump this much mud for the job. Uphole velocity is determined by the flow rate of the mud system, diameter of the borehole and the diameter of the drill pipe. There are many tools, including handbooks, rule of thumb, slide rule calculators and now apps on your handheld device, to calculate velocity. It is always good to remember the time it takes to get the cuttings off the bottom of the well. If you are drilling at 200 feet, then a 100-foot-per-minute velocity means that it would take two minutes to get the cuttings out of the hole. This is always a good reminder of what you are drilling through and how long ago it was that you drilled it. Ground conditions and rock formations are ever changing as you go deeper. Wouldn’t it be nice if they all remained the same?

Centrifugal-style mud pumps are very popular in our industry due to their size and weight, as well as flow rate capacity for an affordable price. There are many models and brands out there, and most of them are very good value. How does a centrifugal mud pump work? The rotation of the impeller accelerates the fluid into the volute or diffuser chamber. The added energy from the acceleration increases the velocity and pressure of the fluid. These pumps are known to be very inefficient. This means that it takes more energy to increase the flow and pressure of the fluid when compared to a piston-style pump. However, you have a significant advantage in flow rates from a centrifugal pump versus a piston pump. If you are drilling deeper wells with heavier cuttings, you will be forced at some point to use a piston-style mud pump. They have much higher efficiencies in transferring the input energy into flow and pressure, therefore resulting in much higher pressure capabilities.

Piston-style mud pumps utilize a piston or plunger that travels back and forth in a chamber known as a cylinder. These pumps are also called “positive displacement” pumps because they literally push the fluid forward. This fluid builds up pressure and forces a spring-loaded valve to open and allow the fluid to escape into the discharge piping of the pump and then down the borehole. Since the expansion process is much smaller (almost insignificant) compared to a centrifugal pump, there is much lower energy loss. Plunger-style pumps can develop upwards of 15,000 psi for well treatments and hydraulic fracturing. Centrifugal pumps, in comparison, usually operate below 300 psi. If you are comparing most drilling pumps, centrifugal pumps operate from 60 to 125 psi and piston pumps operate around 150 to 300 psi. There are many exceptions and special applications for drilling, but these numbers should cover 80 percent of all equipment operating out there.

The restriction of putting a piston-style mud pump onto drilling rigs has always been the physical size and weight to provide adequate flow and pressure to your drilling fluid. Because of this, the industry needed a new solution to this age-old issue.

Enter Cory Miller of Centerline Manufacturing, who I recently recommended for recognition by the National Ground Water Association (NGWA) for significant contributions to the industry.

As the senior design engineer for Ingersoll-Rand’s Deephole Drilling Business Unit, I had the distinct pleasure of working with him and incorporating his Centerline Mud Pump into our drilling rig platforms.

In the late ’90s — and perhaps even earlier —  Ingersoll-Rand had tried several times to develop a hydraulic-driven mud pump that would last an acceptable life- and duty-cycle for a well drilling contractor. With all of our resources and design wisdom, we were unable to solve this problem. Not only did Miller provide a solution, thus saving the size and weight of a typical gear-driven mud pump, he also provided a new offering — a mono-cylinder mud pump. This double-acting piston pump provided as much mud flow and pressure as a standard 5 X 6 duplex pump with incredible size and weight savings.

The true innovation was providing the well driller a solution for their mud pump requirements that was the right size and weight to integrate into both existing and new drilling rigs. Regardless of drill rig manufacturer and hydraulic system design, Centerline has provided a mud pump integration on hundreds of customer’s drilling rigs. Both mono-cylinder and duplex-cylinder pumps can fit nicely on the deck, across the frame or even be configured for under-deck mounting. This would not be possible with conventional mud pump designs.

Centerline stuck with their original design through all of the typical trials and tribulations that come with a new product integration. Over the course of the first several years, Miller found out that even the best of the highest quality hydraulic cylinders, valves and seals were not truly what they were represented to be. He then set off on an endeavor to bring everything in-house and began manufacturing all of his own components, including hydraulic valves. This gave him complete control over the quality of components that go into the finished product.

The second generation design for the Centerline Mud Pump is expected later this year, and I believe it will be a true game changer for this industry. It also will open up the application to many other industries that require a heavier-duty cycle for a piston pump application.

I’ve run into several instances of insufficient suction stabilization on rigs where a “standpipe” is installed off the suction manifold. The thought behind this design was to create a gas-over-fluid column for the reciprocating pump and eliminate cavitation.

When the standpipe is installed on the suction manifold’s deadhead side, there’s little opportunity to get fluid into all the cylinders to prevent cavitation. Also, the reciprocating pump and charge pump are not isolated.

The gas over fluid internal systems has limitations too. The standpipe loses compression due to gas being consumed by the drilling fluid. In the absence of gas, the standpipe becomes virtually defunct because gravity (14.7 psi) is the only force driving the cylinders’ fluid. Also, gas is rarely replenished or charged in the standpipe.

Installing a suction stabilizer from the suction manifold port supports the manifold’s capacity to pull adequate fluid and eliminates the chance of manifold fluid deficiency, which ultimately prevents cavitation.

Another benefit of installing a suction stabilizer is eliminating the negative energies in fluids caused by the water hammer effect from valves quickly closing and opening.

The suction stabilizer’s compressible feature is designed to absorb the negative energies and promote smooth fluid flow. As a result, pump isolation is achieved between the charge pump and the reciprocating pump.

The isolation eliminates pump chatter, and because the reciprocating pump’s negative energies never reach the charge pump, the pump’s expendable life is extended.

Investing in suction stabilizers will ensure your pumps operate consistently and efficiently. They can also prevent most challenges related to pressure surges or pulsations in the most difficult piping environments.

Sigma Drilling Technologies’ Charge Free Suction Stabilizer is recommended for installation. If rigs have gas-charged cartridges installed in the suction stabilizers on the rig, another suggested upgrade is the Charge Free Conversion Kits.

The crank gear and connecting rods drive a rotary movement that is transferred by the motor transmission. The pressure is produced by the piston in the cylinder due to which the mud is sucked. Following the operation, the suction valve is closed when it moves to left. As the pressure increase in the pipeline, the valve is forced to open and mud is released.

In accordance with the operating liquid displacer type being incorporated, the pumps are subdivided into piston units and plunger-type units. The liquid discharge uniformity is independent of head. The pumping plants are used actively for the processes with the liquids containing solid inclusions in high amounts. Incorporating the self-suction function in piston unit, the liquid is sucked and discharged twice in mud pumps during the single shaft turn, making themselves the double-action pumps whereas, the mud plunger pumps are single-action pumps where the liquid is sucked and discharged only once during a shaft turn.

The single direct-action three-piston pumps prove to be better than other types of drilling. These pumps demonstrate much more uniformity in mud delivery, lesser weight, and easy mounting when compared with two-cylinder units.

Depending on the number of cylinders, the pumping plants are classified into the following categories, single-cylinder, double-cylinder, three-cylinder and multi-cylinder pumping plants. These cylinders may be vertical or horizontal. Comparatively, the multi-cylinder pumping plants will cost higher but don’t feature any significant advantages other than the single-cylinder.

When drilling, there might occur the necessity of mud pumping out- and flushing-out, so there are various types of pumps available for such operations which are required to be installed on drilling rigs.

Sucker-rod pumps: In sucker-rod pumps, the pumpjack is a driver. This pump is installed at the bottom of the well. The reciprocating movements of the pumpjack are converted into liquid flow by the pump, which results in delivery of liquid on the surface. These pumps move oil with various admixtures demonstrating high level of capacity.

Screw pumps:The screw pumps are small-sized and are generally used to deliver mud into a centrifuge. These pumps have the rotor and stator as the major structural components and the material used to manufacture these components suit right for smooth pumping of liquids with solid inclusions and high level of viscosity. The pumped liquid flows with stable pressure, shaft slowly and the flow is free of vortexes. These pumps comparatively require minimum service.

Well pumps: These pumps are submerged into wells. The ground part of the plant is a transformer substation equipped for start and adjustment. The pump has a vertical structure, with a fixed cylinder and single-action. A plunger and valve are moving parts. The pumped liquid may contain water content of up to 99% at the temperature as high as 130ºC.

All the mud pumps have few general advantages that include the capability to process liquids and substances with high level of viscosity and with admixtures. Also, enabling the smooth flow of substances, free of pulsations or suspensions mixing are counted under the major advantages of incorporating mud pumps. The pumps have high suction power and small weight, easing out the transportation and installation at remote oil fields. They are highly reliable and also affordable.

There are various types of mud pumps available for different purposes. So, it is important to incorporate the right one for your purpose. A Professional help in getting the right mud pump would be a good and safe option.

The mud pump is the heart of mud rotary drilling. This crucial piece of equipment is responsible for removing the cuttings produced when drilling a water well. Sure, on the surface, the mud pump might not be the most exciting part of a water well drilling rig. But if your crew relies on mud rotary drilling methods, your operation will literally be stuck in the mud without the proper mud pump — no matter how much horsepower and torque your drill sends down the borehole.

To better understand why the mud pump should be a key consideration when selecting a water well drill we need to take a closer look at this un-sung hero of water well drilling.

Despite its simplicity, the humble mud pump plays an important part in overall drilling efficiency. As crew members drill, the drill bit produces cuttings. These pile up in the bottom of the borehole and prevent crews from making progress – like trying to dig a hole with a shovel but throwing the dirt back into the hole every time. Mud pumps offer a solution.

Water is pumped from the mud pump to the drill pipe where it exits through the holes in the drill bit — which may be several inches or hundreds of feet deep in the borehole. Water fills the borehole, forcing the loose cuttings up and out of the hole.

Instead, we put the drilling process first. Lone Star Drills has spent decades growing its drill lineup based not just on specs, but on grueling real-world performance. No one knows better than the person in the field, so we’re constantly sending out new mud pumps and new designs to our customers across the globe and innovating our mud pumps to maximize efficiency.

But keep in mind the mud pump is only part of the overall water well drilling rig. How the whole system works together will determine water well drilling effectiveness. For example, our drills incorporate a three-way valve with a bypass so crews can quickly divert the flow of water from the mud pump, add drill pipe, reconnect water flow and continue drilling all within seconds. Drills that don’t have this feature require crews to fully shut down the mud pump to stop water flow, add drill pipe and power back on the mud pump to restart water flow — a burdensome process for deep wells that require dozens of pipe sections.

Proper mud pump pairing is the key to efficient water well drilling. That’s why Lone Star Drills offers a variety of mud pumps to match the drill for optimal performance. We offer both gasoline- and diesel-powered pumps offering up to 13 horsepower for achieving greater depths.

In addition to flushing cuttings, the mud pump helps stabilize the borehole, as the mixture of water and mud keeps it from collapsing. Using the mud pump, crews can even add bentonite to the pumped water to create a coating that binds to the borehole walls and prevents water from escaping.

Function: Mud Pump Liner also called the cylinder liner. The cylinder liner is the core accessory of the mud pump, which has the functions of storing mud, bearing pressure and completing the suction and discharge of mud. Because the cylinder liner is in direct contact with the mud, it is easy to be worn and corroded by the tiny sand particles, acid and alkali liquid in the mud during work. As a result, the inner diameter of the cylinder liner becomes larger, leakage occurs in the seal between the cylinder liner and the piston, and the pressure is reduced. The cylinder liner is scrapped eventually. Cylinder liner is a one-time wearable part that cannot be reused, and its life span directly affects the normal operation and cost of the drilling operation.

Bimetal Liners are also known as double metal liners. Forged steel pipe 45# (ASTM1045) is used for the outer sleeve, the normalizing hardness: 160BHN (HB180-200); elongation: 17%; tensile strength is not less than 85000PSI; yield strength is not less than 60000 PSI; The inner sleeve material is high chromium wear-resistant cast iron, with chromium content of 26-28%; thickness is 0.25 to 0.35 inches (6.35-8.89 mm), and the standard thickness is 7 mm. Usually, the service life is 800 hours under normal drilling conditions.

The inner liner is made of zirconia or aluminium oxide, and the outer sleeve is made of 45# (ASTM1045) forged steel. It has the advantages of more wear resistance, corrosion resistance, high-pressure resistance, high-temperature resistance, high strength and high hardness than metal cylinder liners. The service life is more than 4000 hours under normal drilling conditions.

The piston assembly is one of the main parts of the hydraulic end system of the mud pump, and it is also one of the vulnerable parts of the drilling work. The discharge pressure of the mud pump is generated by the reciprocating linear movement of the piston assembly in the piston.

The piston assembly is composed of piston hub, rubber, snap ring, plate, etc. The material of the piston hub is 42CrMo (ASTM4140), and the material of the piston rubber is NBR rubber or Polyurethane Rubber.

NBR rubber is suitable for an ordinary drilling working environment with working pressure below 20Mpa, and the working temperature is not higher than 120℃. Excellent wear resistance, chemical resistance and long service life.

Polyurethane rubber has excellent oil resistance and wear resistance. The working temperature is not higher than 120℃, which is suitable for oil-based mud with working pressure below 35Mpa and working environment with high sand content.
