mud pump slide upper brands

Houston, Texas -- To eliminate equipment compatibility issues and the prospect of additional spare-parts inventories for drilling contractors, the LeTourneau Ellis Williams Company (LEWCO) can factory-equip its heavy-duty W-Series and general-duty WH-Series mud pumps with virtually any major brand of fluid end module. Customers not specifying a particular brand receive LEWCO"s standard one-piece or two-piece fluid end modules made of quenched and tempered forged steel, featuring "off the shelf" expendables readily available from domestic and international sources.

LEWCO mud pumps are in-house manufactured. For maximum quality assurance -- with job-ready performance verified in advance -- every pump is tested under full load prior to shipment, in the company"s fully equipped, million-dollar "mud pump laboratory." LEWCO pumps provide input ratings of 300 to 3,000 horsepower (224 kW to 2,237 kW) and deep-drilling discharge pressures as great as 7,500 pounds per square inch (527 kg/cm2). Their premium components include a pressurized lubrication system that force-feeds lubricant to all power-end bearings including upper and lower crosshead slides; a balanced forged steel crankshaft that reduces noise and vibration and helps extend component life throughout the pump; and a robust frame of double-wall, welded-steel, mounted on a heavy-duty oilfield skid.

The LeTourneau Ellis Williams Company builds high-performance mud pumps for oil and gas drilling (on land and offshore), petroleum production and processing, well-servicing, and horizontal directional drilling; as well as ancillary drilling products including pulsation dampeners; drawworks; rotary tables, transmissions, and drives; and swivels. Located in Houston, Texas, LEWCO is a wholly owned subsidiary of LeTourneau Incorporated, a leading manufacturer of self-elevating offshore drilling rigs, forestry equipment, and wheel loaders.

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.

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.

1899 Robert Blackmer invents rotary vane pump technology, a pump design that was an important departure from the old gear principle and predecessor to today"s sliding vane pumps.

1902 Aldrich Pump Company begins manufacturing the world"s first line of reciprocating positive displacement pumps for steel mills and mine dewatering.

1908 Hayward Tyler creates its first electric motor for use under water and develops the wet stator motor for use as a boiler circulation glandless motor-pump.

1911 Jens Nielsen builds the first internal gear pump, founding the Viking Pump Company. The Viking Rotary “Gear-Within-A-Gear” pump (the first of its kind) is placed on the market.

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.

1939 Dorr-Oliver Pump Company develops the Oliver Diaphragm Slurry pump for slurry transfer. Originally designed for mining slurry transfer with their associated acids, it developed into a Primary Sludge Underflow Pump for the wastewater industry starting in the 1970s after the Clean Water Act.

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.

1948 Smith Precision Products Company receives the patent for the first mechanical seal supplied for liquefied gas transfer pumps. It was first put into production in 1947.

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.

1965 Warren Rupp"s heavy-duty, diverse AODD pump is introduced to the industrial market to address the vigorous demands of the steel mills and other industrial market applications.

1968 The ownership of Stenberg-Flygt AB is transferred to the American multinational enterprise ITT (International Telephone & Telegraph Corporation). Prior to this transfer, Stenberg-Flygt AB, AB Flygts Pumpar and Flygt International AB are consolidated as a single company.

1980s Gorman-Rupp unveils the nutating pump, a special purpose small pump used in health care applications; additional energy-efficient, self-priming centrifugal pumps; a series of lightweight portable pumps and high-pressure pumps with the first digital-control panels.

1985 Sims manufactures the first structural composite pump, all Simsite Vertical Pit Pump. Sims later won the Innovative Product Award for these products in 1990.

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.
