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 2,200-hp mud pump for offshore applications is a single-acting reciprocating triplex mud pump designed for high fluid flow rates, even at low operating speeds, and with a long stroke design. These features reduce the number of load reversals in critical components and increase the life of fluid end parts.

The pump’s critical components are strategically placed to make maintenance and inspection far easier and safer. The two-piece, quick-release piston rod lets you remove the piston without disturbing the liner, minimizing downtime when you’re replacing fluid parts.

Mud pump, refers to the drilling process to the drilling mud or water and other washing liquid machinery. The main components are volute, impeller, pump seat, pump case, support cylinder, motor seat, motor and other components. Impeller nut is cast iron, so corrosion resistance is good, and convenient processing technology. Pump seat is equipped with four skeleton oil seal and shaft sleeve, prevent shaft wear, prolong the service life of the shaft.

High quality vertical mud pumps with thick, solid shaft and copper motor can be provided in ATO shop. Various models are available, such as 2 inch mud pump, 3 inch mud pump, 4 inch mud pump and 6 inch mud pump. Here is the price list of vertical mud pump.

Sewage mud pump is used in mining, papermaking, printing and dyeing, environmental protection, ceramics, refining, petroleum, chemical industry, farm, dyeing, brewing, food, construction, gold mine, mud, quicksand, mud pond, sewage pond, turbid fluid to send suction thick liquid, loading and suspended matter sewage operation, can also be used for mine drainage and fluid containing mud blocks.

If the mud pump and high-pressure water pump, water gun with the composition of hydraulic mechanized earthwork unit, can be used for land leveling, river and pond dredging, digging and other small water conservancy projects, as well as urban air defense engineering, underground engineering.

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.

A mud pump is a piston driven pump design that can produce high-pressure operations to safely transfer high viscosity fluids over an extended depth. The mud pump has many applications in industrial service, but it has proven to be invaluable in many drilling operations. Let"s take a look at mud pumps and why they are such a good fit for the industries they serve.

A Mud pump is a reciprocal pump design utilizing a piston in a cylinder to transfer fluids under high pressure. A mud pump can generate up to 7,500 psi (52,000 kPa) during normal operations. Mud pumps are a positive displacement design.

Mud pumps are available in a variety of configurations and sizes. However, mud pumps tend to be one of two main types: the duplex and the triplex. The duplex mud pump features two pistons (or plungers) in constant action to move the fluid.

The triplex mud pump has all but replaced the duplex version in most applications, although you will still find the latter in use in some smaller countries. The triplex mud pump features a triple piston (plunger) design that is more efficient than the duplex design.

The latest designs of the mud pump are the quintuplex and hex versions. As the name suggests, these designs feature five or six pistons in a reciprocating design. Although not in widespread use as compared to the triplex design, these mud pumps spread the pumping action across the rotational cycle, creating less mud noise. This allows for better measurements and logging to take place while in operation.

There are two main parts to a mud pump: the fluid end and the power end. The fluid end is where the actual pumping takes place. The components of the fluid end consist of valves, pistons (or plungers), and liners.

Since the fluid end is in constant contact with the material being pumped, most modern designs allow for quick replacement of worn components as needed. This dramatically extends the life of a unit without having to completely replace the pump.

The power end of a mud pump is responsible for taking the input power, typically through a driveshaft, and converting it into the reciprocating motion needed for the pistons. In most mud pump applications, the power end uses a crosshead crankshaft for this conversion.

Rotational power is supplied to the mud pump through an external power source. The power end of the pump converts this rotational energy through a crankshaft to a reciprocating motion that moves the pistons.

Due to the pressure and material being pumped, most mud pump applications can create a lot of vibration. To combat this, many mud pump applications incorporate pulsation dampeners. These are typically used on both suction and discharge sides of the pump.

In some cases, a positive displacement pump may pull the fluids at a pressure lower than its vapor pressure. When this happens, damaging cavitation can take place. In these cases, a charge pump might be required at the inlet side to maintain a positive pressure on the suction stream.

When selecting a mud pump, there are two main parameters to be used, pressure and displacement. Pressure is the net pumping pressure that the pump can safely provide. The requirement for pressure increases as the drilling depth and fluid (or slurry) viscosity increases.

Displacement is the volume of fluid that the pump can transfer within a given time period. In most applications, this is rated as discharged liters per minute.

Mud pumps are ideal wherever a lot of fluid needs to be pumped under high pressure. They are considered an essential part of most oil well drilling rigs. Mud pumps can deliver high concentration and high viscosity slurry in a stable flow, making them adaptable to many uses.

Mud pumps are an invaluable tool when high pressure and high viscosity fluids are needing to be transferred. Mader Electric, Inc. specializes in mud pump repair and installation, as well as pump training. Contact us to see how we can help with your pumping needs.

An integral part of onshore and offshore drilling, mud pumps circulate the drilling fluids used to facilitate drilling oil and natural gas wells. Used to stabilize pressure and support the well during the drilling process, drilling fluids also provide friction reduction and a means to remove cuttings.

While drilling with some type of fluid has been in practice for centuries, the term "drilling mud" was coined when a herd of cattle was driven through a wet field near Spindletop, and the resulting mud was used to lubricate the drillstring and drill bit. Drilling fluids have come a long way since those early days of drilling, and offshore mud pumps are constantly taxed to help operators find and develop hydrocarbons in harsher, deeper and more difficult locations.

"A mud pump delivers drilling fluid from the mud tanks, through the top drive, down the drill string and through the bit," explained Juan Lerma, Mud Pumps Product Line Manager at National Oilwell Varco. "When the mud exits the bit, it travels back to the surface carrying the cuttings made by the bit where it flows over a shale-shaker removing the cuttings, cleaning the mud and returning it to the tanks, where it"s used over and over again."

Varying according to the conditions of well being drilled, as well as the type of rock formations the bit is encountering at each depth, drilling fluids are composed of numerous ingredients, including clay, water, oil and synthetic materials. When drilling offshore, the environmental impact of drilling fluids must be more closely considered.

"A mud pump is one of the critical and required pieces of equipment for a drilling rig whether on land or offshore," Lerma stated. "Offshore, where real estate is at a premium, mud pumps are configured with a compact top-mounted drive system, reducing the overall length with a smaller package and strategically placing it in the pump room for permanent installation."

"On the other hand, space is not as much of an issue on land rigs," continued Lerma. "Here special consideration is paid to truck specifications and height restrictions for travel on roads, instead."

"Jackups semis and drillships all use the same mud pumps; however, the number of pumps installed in the pump rooms changes from rig to rig depending on the drilling specifications," explained Lerma.

Additionally, the rock formations and pressure encountered when drilling may vary; HT/HP and environmental conditions also may affect the drilling process, as well as the drilling fluids chosen and mud pumps required.

"As the drilling programs require higher flows and higher pressures, it is necessary to increase pressure ratings and either increase the number of mud pumps required or utilize larger capacity mud pumps," Lerma continued. "Most early jackups utilized two mud pumps and piping systems rated for 5000 psi work pressures and 1600 horsepower, while most of today"s jackups have 7500 psi working pressure and up to four 2200 HP pumps piping systems."

According to information gathered by premium rig data service RigLogix, National Oilwell Varco leads the pack in providing mud pumps to offshore oil rigs. Of the top six brands of mud pumps, NOV supplies four of them, garnering more than 70% of the offshore mud pump market.

Those leading NOV brands include National Oilwell, Continental Emsco (which was acquired by NOV in 1999), National and NOV. The other leading mud pump system is provided by Gardner Denver and is the third most popular type of system offshore. Additionally, Lewco, a division of Rowan, has about 4% of the offshore mud pump market, putting it fifth on the list of leading suppliers.

With more than four decades of experience providing the offshore industry with mud pumps, Lerma revealed that the company has been able to sustain such a high market share by constantly transforming the product to meet the needs of the industry. As offshore drilling programs have required higher flows and pressures, the company has strived to provide the best quality equipment, while maintaining the lowest cost of ownership.

To better serve its offshore clients, the company developed the Hex Pump in the last several years, and this new line of mud pumps has proven a success in offshore waters worldwide. Boasting 2400 HP, the Hex pump is capable of delivering up to 1,034 gallons of drilling fluids per minute, making it one of the most powerful mud pumps on the market today.

In 2004, the first two Hex Pumps were deployed on a Global Santa Fe rig working offshore West Africa, and in 2005, both the Noble Max Smith and the Noble All While started using the Hex Pump as well. In fact, the Noble Al White, working in the harsh conditions of the North Sea, was the first rig to be solely dependent on the Hex Pumps with two of them located in its pump room, and the rig now has more than 8,000 hours of successful drilling operations using the system.

Through these successes, the company has been able to lock in orders for many of the newly built and under-construction offshore rigs joining the global fleet now and in the future.

"The first drillship to use the system, Transocean"s Discoverer Clear Leader just started drilling in the Gulf of Mexico with five Hex Pump systems," said Lerma. "Additionally, the soon-to-start-drilling Discoverer Americas houses four Hex Pumps, and the soon-to-be-delivered Discoverer Inspiration will have five."

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 which must manually move the drill cuttings out of the waste bin or roll-off box and into the truck. 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.

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.

Within the petroleum industry centrifugal pumps are necessary in order to process fluids especially hydrocarbons. Another important application within the petroleum industry is in the mud circuit on a drilling rig. On drilling rigs, mud which consists mainly of water and bentonite as well as of several different additives depending on many different factors is used. The heart of the mud circuit is the mud pump which is in general a high pressure piston pump. It provides the major part of head to overcome the system’s resistance. The mud is pumped through a piping system to the derrick and through the standpipe to a definite high. Now through the kelly hose via the gooseneck into the upper kelly cock. It flows through the Kelly and the lower kelly cock into the drill string down the borehole. At its end, the mud leaves the drilling collars through the drilling bit.

1. Select a pump to handle the highest anticipated flow. Select an impellersize to provide sufficient discharge head to overcome friction in the lines,lift the fluid as required, and have sufficient head remaining to operatethe equipment being fed.

Initially this guideline suggested that the pump flange size be selected to provide the highest anticipated flow, even though the flange size has nothing to do with the flow rate. Most pump curves are listed in terms of the flange sizes. The size of the pump impeller housing increases as the flange size increases. An impeller rotating at constant speed will create a constant head independent of the size of the housing or the flanges. An impeller that fits inside a 2×3, 3×4, 4×5, or 5×6 pump will produce the same head in each pump if it is rotated at the same speed. Because the housing of a pump with a 2-inch and 3-inch flange is smaller, the internal friction at a high flow rate will be greater than a 56 pump. This means that the capacity of the various pump sizes will be indicated by their flange sizes. The committee decided to only indicate that the pump should be selected to handle the highest anticipated flow rate, instead of indicating that the flange size is commonly used to specify pump size.

2.Install the centrifugal pump with a flooded suction that is sumped so thatsufficient submergence is available to prevent vortexing or air-locking.Foot valves are not needed or recommended with flooded suctions.

A small influx of air into the suction of a centrifugal pump can create cavitation problems and diminished flow. As the air enters the chamber with the impeller, it tends to concentrate in the center of the impeller because of the centripetal acceleration of the drilling fluid.

The liquid continues to move through the pump. The air does not always continue to the impeller tip, but tends to remain in the center of the impeller. This bubble of air forms a barrier for the incoming fluid, which diminishes the flow rate into the pump. The air also experiences a significant decrease in pressure—possibly even below atmospheric pressure. This causes implosions of vapor bubbles that can remove metal from the impeller. The pump will sound as if it is pumping gravel. If it continues in this mode for a long period of time, the impeller will be severely damaged.

Flooded suctions tend to eliminate most of the air influx problems but sometimes a small vortex will form in the mud tank. These small vortexes can entrain a significant amount of area. Increasing agitation in the tanks may prevent a coherent cylinder of air from reaching the suction line. Alternatively, a plate can be installed in the tank to interrupt the formation of a vortex.

In some cases, a centrifugal pump is placed on the ground above a pond or buried tank. Foot valves are needed if the centrifugal pump is operated above the liquid level of the suction tank. Foot valves are check valves that prevent the suction line from draining when the pump is turned off. Care must be taken to eliminate tiny air leaks in the suction line because the absolute pressure will be below atmospheric pressure. The pump and suction line should be filled with fluid before the pump motor is started. Centrifugal pumps do not move air very well.

A centrifugal pump suction can only lift fluid a certain height above a liquid level. These heights are determined by observing the NPSH (negative pressure suction head) values listed on the centrifugal pump curves. If the NPSH is exceeded, cavitation can destroy the impeller.

Horizontal pipes will fill with solids until the flow rate reaches 5 ft/sec. Barite in equalizing lines between mud tanks is normally settled until the velocity between the tanks reaches 5 ft/sec. Increasing the diameter of connection lines only causes more barite to settle. Above 10 ft/sec, pressure losses in the pipe become too great. Elbows and swages tend to cause turbulence in the flow stream, which can lead to cavitation.

5. Eliminate manifolding. One suction and one discharge per pump ismost cost effective over time. Do not manifold two pumps on the samesuction line. Do not pump into the same discharge line with two or morepumps.

Flexibility of piping so fluid can be pumped from any tank through any equipment to any other tank has created more problems over the years than just about any other concept. A properly plumbed system should require only one suction and one discharge for each piece of solids-removal equipment. Ignoring this rule allows rig hands the opportunity to open or close the wrong valves. A leaky or incorrectly opened valve can reduce drilled-solids removal efficiency by up to 50%. This translates to an expensive drilling-fluid system. This problem can be eliminated by storing an extra pump and motor. Arrange the centrifugal pumps and motors so that they may be easily replaced. If a pump or motor fails, simply replace the unit. The damaged unit can be replaced during routine maintenance. Two centrifugal pumps in parallel will not double the head available to equipment because a centrifugal pump is a constant head device. For example, visualize a standpipe that is constantly filled with fluid. If two standpipes of approximately the same height are connected, the flow from both pipes will almost equal the flow from one standpipe. If fluid stands lower in one standpipe than the other. fluid will flow from the highest standpipe to the lowest standpipe. This same flow occurs when two pumps are connected in parallel—fluid will flow backward through one of the pumps.

6. Install a pressure gauge between the pump discharge and the first valve.When the valve is closed briefly, the pressure reading may be used fordiagnostic evaluation of the pump performance.

A centrifugal pump uses the smallest amount of power when no fluid is moving through the pump (that is, when the discharge valve is completely closed). If the valve remains closed for longer than 5 minutes, the fluid within the pump will become hot from the impeller agitation. This hot fluid may damage the seals. Closing the valve for a short time allows a good reading of the no-flow head produced by the pump. This reading should be compared with the pump manufacturer’s charts. The diameter of the impeller can then be determined. (A pump may be stamped 5X6X14. This means that it could house a 14-inch impeller but it does not mean that it has a 14-inch impeller. The impeller size is adjusted so the pump will deliver the proper head.) After the pump has been in service for a period of time, the pressure reading will assess the condition of the impeller. This eliminates the need to dismantle the pump for inspection. If the manifold pressure is incorrect, reading the pump no-flow discharge head will assist in troubleshooting.

7.Keep air out of the pump by degassing the mud, having adequate suctionline submergence, and installing baffles to break mixer vortices. Properly sized, baffled, and agitated compartments will not vortexunless the drilling fluid level becomes extremely low.

Centrifugal pumps cannot pump aerated fluid. The air tends to gravitate toward the center of the impeller while the liquid moves toward the outside. This creates an air bubble at the center of the impeller. When the air bubble becomes as large as the suction line diameter, fluid will no longer enter the pump. This is called airlock. Only a small cylinder of air vortexing into the pump is sufficient to prevent the pump form moving liquid. Since the air accumulates over a period of time, a small vortex the size of a pencil is sufficient to eventually shut down a 6×8 pump. Baffles are inexpensive and easily installed in an empty tank. Any vertical surface that disrupts the swirling motion of the fluid in a compartment is usually sufficient to destroy a vortex. Rig pump efficiency can decrease from 99 to 85% efficiency if the drilling fluid content rises to 6% volume. Air in the drilling fluid may be calculated by measuring the pressurized and unpressurized mud weight.

8. Do not restrict the flow to the suction side of the pump. Starving thepump suction causes cavitation and this will rapidly damage the pump.When a pump begins cavitating, small vacuum bubbles adjacent to the impeller surface start imploding. The pump sounds as if it is pumping gravel. The implosions quickly remove metal from the surface to the impeller blade. In a very short period of time, holes will appear in the metal. Important: Do not close a valve on the suction line while the pump is running!

Starving the suction will decrease the output head. If the head, or pressure produced by the pump, is too high, change to a smaller diameter impeller. On a temporary basis, a discharge valve can be partially closed. On a long-term basis, however, considerable valve erosion will occur so a new, properly sized impeller is necessary. Even a large centrifugal pump is not damaged if only 10 to 20 gpm is discharged from the pump. In fact, the lower flow rates will require less horsepower to the motor than pumping fluid at a much higher flow rate.

Centrifugal pumps will pump fluid even if running in reverse. The head produced by the pump will be lower than it should be. The pressure gauge installed between the pump and the first valve will assist with the diagnosis. Usually, switching two wires in the lead-in panel box will correct the rotation.

10.Startup procedure for an electric motor–driven centrifugal pump with avalve on the discharge side between the pump and the equipment beingoperated is to start the pump with the valve just slightly open. Once thepump is up to speed, open the valves slowly to full open. This approachwill reduce the startup load on the electric motor and will reduce theshock loading on equipment such as pressure gauges and hydrocyclones.

An alternative startup procedure is to completely close thedischarge valve before startup and then open the valve slowly immediatelyafter startup to prevent overheating and possible damage to thepump seals.

An electric motor–driven centrifugal pump will immediately try to produce a constant head when it is turned on. If the pump is pumping into an empty line, the flow rate is enormous. Very high flow rates require very high currents to the electric motor. Circuit breakers can stop the pump and avoid motor burnout. Lower horsepower is required if the pump is started with the discharge valve closed.
