Mud Pumps come in both electric and gas / diesel engine drive along with air motors. Most of these pumps for mud, trash and sludge or other high solids content liquid dewatering, honey wagon and pumper trucks. Slurry and mud pumps are often diaphragm type pumps but also include centrifugal trash and submersible non-clog styles.

WARNING: Do not use in explosive atmosphere or for pumping volatile flammable liquids. Do not throttle or restrict the discharge. Recommend short lengths of discharge hose since a diaphragm mud pump is a positive displacement type and they are not built with relief valves.

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.

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.

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.

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.

Castle Pumps were approached by an oil and natural gas company installing a new piece of drilling equipment aboard their offshore platform. They required high viscosity pumps to transfer the oil based mud which is a fluid used during the drilling process. The viscosity of oil based mud can vary and it contains both soft and hard solids. There were various special requirements for these oil based mud pumps including explosion proof ATEX motors, dry running protection devices and variable speed drives.

We have experience with transferring viscous slurries and knew our range of progressive cavity pumps would be well suited for the application. The Diamond series can handle up to 1,000,000CP and is able to transfer both soft and hard solids in suspension.

We supplied progressive cavity pumps complete with ATEX motors, planetary variable speed drives and thermic probes that protect the pumps against dry running. To ensure the pumps were as reliable as possible and to avoid any down time, we also supplied two years operational spares for the pumps including stators and rotors. Further to that, we supplied counter flanges for the pumps to allow them to be installed immediately when they arrived at site.

These progressive cavity pumps were manufactured in under five working weeks and packed in wooden crates according to ISPM 15 and delivered directly to site in Angola. This project is another example of Castle Pumps’ flexibility in ensuring all of the customer’s requirements are met.

Editor"s Note: This is the second of five parts of our feature, The History of Pumps. This timeline was developed through research, credible sources and the knowledge of friends in the industry, The history of pumps is long and illustrious. This account represents highlights of some of the major historical and technological developments. We welcome your contributions.

200 BC Greek inventor and mathematician Ctesibius invents the water organ, an air pump with valves on the bottom, a tank of water in between them and a row of pipes on top. This is the principal design that is now known as the reciprocating pump.

200 BC Archimedean screw pump is designed by Archimedes is considered one of the greatest inventions of all time and is still in use today for pumping liquids and granulated solids in both the industrialized world and in the third world—where it is a preferred way to irrigate agricultural fields without electrical pumps.

1475 According to Reti, the Brazilian soldier and historian of science, the first machine that could be characterized as a centrifugal pump was a mud lifting machine that appeared in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini.

1588 Sliding vane water pump technology is described by Italian engineer Agostino Ramelli in his book “The Diverse and Artifactitious Machines of Captain Agostino Ramelli,” which also included other pump and engine designs.

1636 Pappenheim, a German engineer, invents the double deep-toothed rotary gear pump, which is still used to lubricate engines. This gear pump made it possible to dispense with the reciprocating slide valves used by Ramelli. Pappenheim drove his machine by an overshot water wheel set in motion by a stream and was used to feed water fountains.  The emperor Ferdinand II granted him a “privilege” - the equivalent of a patent - in respect of this invention.

1675 Sir Samuel Moreland—an English academic, diplomat, spy, inventor and mathematician—patents the packed plunger pump, capable of raising great quantities of water with far less proportion of strength than a chain or other pump. The piston had a leather seal. Moreland"s pump may have been the first use of a piston rod and stuffing box (packed in a cylinder) to displace water.

1790 Briton Thomas Simpson harnesses steam power to pumping engines for municipal water applications and founds the London company Simpson and Thompson Co. (predecessor to Worthington Simpson).

1845 Henry R. Worthington invents the first direct-acting steam pumping engine. Worthington Pump designed its first products to power canal boats and U.S. naval vessels. Worthington later pioneered pump designs for boiler feed, oil pipeline and hydro-electric applications.

1851 John Gwynne files his first centrifugal pump patent. His early pumps were used primarily for land drainage, and many can still be seen today in pump house museums. They were usually powered by Gwynnes" steam engines. By the end of the 19th century, Gwynne was producing pumps of all sizes to cover all industrial applications, from small electric pumps to those rated at 1,000 tons per minute. His company had also begun to produce scientific pumps, e.g., porcelain pumps for chemical works. In the 1930s they were producing almost 1,000 different models.

1860 Adam Cameron founds the Cameron Steam Pump Works, and becomes another pioneer in reciprocating steam pump engines. Like Worthington, Cameron"s first products were used to power merchant marine and U.S. naval vessels. Cameron pumps were later applied in water resources, oil pipeline and refining and boiler feed.

1886 Jens Nielsen, founder of Viking Pump Company, invents the internal gear pumping principal while designing a pump to remove excess water that was seeping into his limestone quarry from a nearby creek.

1886 United Centrifugal Pumps is incorporated. It becomes the world"s foremost supplier of high-pressure crude oil and refined product pipeline pumps.

1912 Durion, a universally corrosion-resistant material, is invented by the Duriron Castings Company (later known as Durco Pump) and is applied to process equipment.

1915 Albert Baldwin Wood invents the Wood trash pump. Wood spearheads the reclamation from swamp and the efforts to develop much of the land now occupied by the city of New Orleans. Some of Wood"s pumps have been in continuous use for more than 80 years without need of repairs. New ones continue to be built from his designs.

1916 While Armais Sergeevich Arutunoff first invented submersible pumps in Russia in 1916, their use in the United States did not begin until the 1950s.  Arutunoff first designed his pump for use in ships, water wells and mines. He altered the design to work in oil wells. Thanks to further refinements to Arutunoff"s design, there are more types of submersible pumps, allowing use in other applications such as pumping drinking water, creating fountains and pumping wastewater.

1921 Harry LaBour founds LaBour Pump Company. A pioneer in the development of pumps for the chemical industry, LaBour developed corrosion-resistant alloys to incorporate into his pumps. Until his time, sulfuric acid was always pumped with lead pumps, the only known material that could handle certain concentrations of the acid.

1921 Jeumont-Schneider begins manufacturing water and slurry pumps in Jeumont, France. It later develops solids-handling pumps and segmental ring section multistage pumps.

1924 Durco Pump introduces the world"s first pump specifically designed for chemical processing. It would go on to establish undisputed global leadership in ANSI pump design.

1926 O.H. Dorer receives a patent for the first inducer, which reduces the required NPSH. Inducers did not become incorporated into standard pump lines until the 1960s.

1929 Pleuger incorporates in Berlin, Germany. Its first offerings are submersible motor pumps for dewatering in the construction of underground railways and subways. Pleuger pioneers the first successful application of submersible motor pumps in offshore service.

1929 Stork Pompen produces the first concrete volute pump for drainage, integrating the pump housing in the civil construction of the pumping station.

1930 While inventing a compressor for jet engines, aviation pioneer René Moineau discovers that this principle could also work as a pumping system.The University of Paris awarded Moineau a doctorate of science for his thesis on “the new capsulism.” His pioneering dissertation laid the groundwork for the progressing cavity pump.

1933 The original version of the Bush Pump is designed as a closed-top cylinder pump. In 1960 the design was modernized. The base of the well was from then on bolted to the well casing and got its current name, The Zimbabwe Bush Pump, the National Standard for hand pumps in Zimbabwe. After Zimbabwe"s independence in 1980, the government creates its own modernized version of the pump, B-type Zimbabwe Bush Pump. The pump is today regarded as a national treasure. In 1997, it was pictured on a postal stamp.

1933 J.C. Gorman and Herb Rupp introduce a pump with a “non-clogging” feature. It outperforms any other self-priming centrifugal pump previously invented. The company Gorman-Rupp is established.

1936 Robert Sheen invents the metering pump. The core of his invention was a method of controlled volume that was inherent to the pump. The first pumps were assembled in the basement of his father, Milton Roy Sheen"s, home, where the initial patterns for castings were made.

1937-1939 Smith Precision Products Company (Smith Pumps) designs three pumps, two of which (models 300 and 200) were specifically designed for LP-gas transfer.

1940 Reuben Smith, of Smith Precision Products Company (Smith Pumps), receives the first approval for an LP-gas pump from the California Industrial Accident Commission. This was for the model 4X pump and the approval was a "suitable for use" certificate.

1942 The Gorman-Rupp team creates the first commercially available solids-handling trash pump to respond to the contractor"s need for a pump to withstand the considerable rigors of pumping out trash-laden septic tanks, cesspools and outhouses.

1944 During World War II, Goulds extra-quiet trim pumps are installed in every U.S. Navy submarine. That year, 157 Goulds men went to war and 157 women took their places on the Goulds manufacturing floor. Goulds earned the prestigious Army-Navy “E” Award that year for outstanding production of war materials.

1947 Flygt"s Sixten Englesson, a master of engineering, develops a prototype for the first submersible drainage pump, which is later known as the “parrot cage,” or B-pump, used in mining for construction.

1950  Vanton develops the Flex-i-liner sealless self-priming rotary pump which handles corrosive, abrasive and viscous fluids as well as those that must be transferred free of product contamination.

1954 Smith Precision Products Company (Smith Pumps) begins working with the Underwriters Laboratories to develop their first Standard for liquefied gas pumps, UL-51, which is still in use today.

In 1955, Jim Wilden invented air-operated double-diaphragm pump technology. It had the right air valve and diaphragms needed and was tough and versatile enough to meet the stringent demands of the mining and heavy-construction industries. During the 1980s, Wilden introduced plastic AODD pumps that have the ability to stand up to the harsh operating conditions and corrosive media transferred throughout the global chemical market. Photo courtest of Wilden.

1960s New lines of industrial pumps are developed by Goulds Pumps, including large double suction pumps, higher pressure pumps and non-metallic pumps. In home water systems, the jet water system is improved and a complete line of submersible pumps is completed.

In 1933, J.C. Gorman and Herb Rupp introduced a pump which had a "non-clogging" feature. Their competitors claimed the pump would not work in a savage public awareness campaign to discredit the new design, which resulted in about $100,00 worth of "free advertising." At least one customer was willing to try it. National Ice Company purchased the first pump, and the company Gorman-Rupp was established. Photo courtesy of Gorman-Rupp Company.

1994 Two new major products are introduced by Goulds Pumps, the Industrial Model 3298 Magnetic Drive Pump and the Water Technologies Model GS “Global Submersible.”

1994 Sims receives the honor of approval from the United States Navy for composite centrifugal pump intervals. Simsite was tested and qualified for centrifugal pump replacement parts and was the first composite to be certified.

1994 Baha Abulnaga invents the slurry and froth pump with  a split vane impeller. The split impeller helps to reduce recirculation in slurry pumps by dividing the space between the main vanes without reducing the passageway at the narrowest point, which is the eye of the impeller. In froth pumps, it helps to break up air bubbles that form and tend to block the flow.

1995 Sims manufactures the largest structural composite pumps in the world - two Simsite vertical turbine pumps for Potomac Electric Power Company. They are 40 feet long and 3 feet in diameter.

2006 Sims manufactures the largest structural composite centrifugal impeller in the world. This huge impeller was installed in a cooling tower pump for Puerto Rican Electrical Power Company. It is 50 inches in diameter and consumes 2,000 horsepower.

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.

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.

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 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.
