vintage hand mud pump brands

In 1848 Seabury S. Gould purchased an interests in Downs, Mynderse & Co. and the firm became Downs & Co. Wooden pumps were produced in an old cotton factory building. In 1869, the name of the company was changed from Downs & Company to Goulds Manufacturing Company.

Seabury S. Gould, a man of unusual vision, was the founder of Goulds Manufacturing Company. He keenly watched as the first pump casting emerged from its mold of sand. An iron pump, he believed, would overcome all the disadvantages of a wooden pump. It would be strong and efficient and provide fresh flowing water for the pioneers. He ran the company until after the Civil War.

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.

Below: Marvin and Kathryn Summerfield founded Cascade Pump Company in 1948. They are pictured here at an industry tradeshow in the early 1950s. Photo courtesy of Cascade Pump Company.

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.

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.

Identifying your pump is the first step in replacing it or knowing which repair parts match your pump model. Many customers call us looking to replace their pump but they’re not sure which pump model they have or even who their pump’s manufacturer is. Luckily, your pump has all this information printed on it.

To identify the model of your pump, you need to know the part number. Part numbers, also sometimes referred to as model numbers, can be found on your pump’s tag. A pump tag is a small rectangular plate that displays all the basic information about your pump. Besides a pump’s part number, pump tags can include information like the gallons per minute, total dynamic head, and max working temperature of a pump. The information included on the tag is going to depend on the manufacturer of the pump.

Different types of pumps have their tags in different places. Finding the pump tag is sometimes half the battle. They are usually located on the volute of the pump (or the main body of the pump- the part that’s not the motor). Once you find your pump’s tag, the next step is, understanding what the information on that tag means exactly. If you can’t find your pump’s tag or if the numbers have faded or are hard to read, consult your owner’s manual or other paperwork that came with your product. Most product manuals will indicate where to find the model number.

Different manufacturers label their pumps differently. For example, some of the information printed on the Grundfos tag below might not appear on another brand’s pump or it can be referred to differently. This can be confusing at first so it helps to know who your pump’s manufacturer is and how they refer to their models. Some manufacturers print their logo on the pump.

You might see another similar looking plate on your pump. This is the pump’s motor tag. The motor tag gives information about the motor attached to the pump such as volts and phases. While the pump tag is usually located on the pump’s volute, the motor tag is located on the pump’s motor.

If the tag is missing, try to locate the casting number. Casting numbers are stamped directly in the steel/iron or bronze of the pump. These numbers are a good source of information about the unit.

This is a Bell & Gossett in-line circulator pump tag. The pump tags for these B&G circulators are generally easy to spot on the volute on the pump. On this Bell & Gossett In-Line Circulator pump, we can see the part number is

This next pump is a Zoeller sewage pump. The silver tag is located on the top of the pump. This tag gives us a little more information about the pump.

Nothing in life lasts forever. Luckily PumpProducts.com stocks a wide variety of repair parts for all the most trusted brands in the industry. If you’re not sure of your pump’s manufacturer, series, model number, or can’t find the parts you’re looking for, you can1-800-429-0800 and they’ll help you identify your pump and get you the parts you need.

All the best pump manufacturers in the world rely heavily on providing quality and energy-efficient pump solutions. When choosing the pump manufacturer, you need to consider the location. Importing heavy-duty pumps can attract a lot of logistics costs that you can avoid by choosing a regional pump provider. Cost is another factor you need to consider. US and European suppliers charge a premium amount for products that you can get at a discounted rate from India or other Asian nations. Choosing the proper pump manufacturer can ensure your system’s reliable and cost-effective operations.

Whether onshore or offshore, well drilling sites rely on a multitude of systems to successfully perform the drilling operation. The mud pump is a key component tasked with circulating drilling fluid under high pressure downhole. The mud pump can be divided into two key sections: the power end or crosshead and the fluid end. Proper alignment of the pump’s crosshead to the fluid end liner is necessary to maximizing piston and liner life. Misalignment contributes to

accelerated wear on both the piston and the liner, and replacing these components requires downtime of the pump. Traditional methods of inspecting alignment range from using uncalibrated wooden rods, Faro Arms and micrometers to check the vertical and horizontal alignment of the piston rod OD to the piston liner ID. These are time consuming and cumbersome techniques that are ultimately not well suited to troubleshoot and solve alignment issues.

A “Mud Pump Laser Alignment Kit” enables you to measure where the piston will run through the liner at various positions along the pump’s stroke. It will also project a laser centerline from the fluid end back towards the rear power end of the pump that can be used to determine how much shimming is required to correct any alignment issues. The kit can include either a 2-Axis receiver or a 4-Axis which accepts the laser beam and documents where it falls on the active surface of the receiver. The 4-Axis receiver can decrease alignment time by as much as 50% as it will measure angularity as well as X and Y while the 2-Axis does not and will need multiple measurement locations to get the same information. In addition, the alignment system is a non-intrusive service requiring the removal of only the piston rod which allows for much quicker service and less down time on the pump. As the mud pumps in question are located globally both on and offshore, having a small, portable system is another great advantage. Our recommendation would be Pinpoint laser System’s “Mud Pump Alignment Kit”. They are being used by many of the leading repair service companies and have been their main alignment tool for over 15 years. Manufacturers are also utilizing these for new pump set-up.

For the successful execution of your projects, it is important to find an appropriate company with a good track record. We help you in connecting with the top mud pump manufacturers and companies and get the best quotation.

The most widely used mud pumps across the industry are Triplex Reciprocating Pumps. Their application has gained immense popularity with time because they are 30% lighter than duplex reciprocating pumps with relatively less operational cost. Moreover, through these pumps the discharge of mud is smooth and they are capable of moving large volume of mud at higher pressure.

The different parts of a mud pump are Housing itself, Liner with packing, Cover plus packing, Piston and piston rod, Suction valve and discharge valve with their seats, Stuffing box (only in double-acting pumps), Gland (only in double-acting pumps), and Pulsation dampener. A mud pump also includes mud pump liner, mud pump piston, modules, hydraulic seat pullers along with other parts.

The wearing parts of a mud pump should be checked frequently for repairing needs or replacement. The wearing parts include pump casing, bearings, impeller, piston, liner, etc. Advanced anti-wear measures should be taken up to enhance the service life of the wearing parts. This can effectively bring down the project costs and improve production efficiency.

Triplex plunger-type mud pumps feature a reciprocating, positive displacement pump design utilizing three plungers to safely transfer high-viscosity fluids under high pressure over an extended depth. Although they have many industrial applications, these pumps have become an essential part of oil well drilling rigs where they’re used to provide smooth discharge of mud and debris from oil wells.

In addition to their use in drilling and well service operations, mud pumps are also frequently used to handle corrosive or abrasive fluids, as well as slurries containing relatively large particulates, in applications like commercial car washes, wastewater treatment, cementing, and desalination operations.

If you run a mud rig, you have probably figured out that the mud pump is the heart of the rig. Without it, drilling stops. Keeping your pump in good shape is key to productivity. There are some tricks I have learned over the years to keeping a pump running well.

First, you need a baseline to know how well your pump is doing. When it’s freshly rebuilt, it will be at the top efficiency. An easy way to establish this efficiency is to pump through an orifice at a known rate with a known fluid. When I rig up, I hook my water truck to my pump and pump through my mixing hopper at idle. My hopper has a ½-inch nozzle in it, so at idle I see about 80 psi on the pump when it’s fresh. Since I’m pumping clear water at a known rate, I do this on every job.

As time goes on and I drill more hole, and the pump wears, I start seeing a decrease in my initial pressure — 75, then 70, then 65, etc. This tells me I better order parts. Funny thing is, I don’t usually notice it when drilling. After all, I am running it a lot faster, and it’s hard to tell the difference in a few gallons a minute until it really goes south. This method has saved me quite a bit on parts over the years. When the swabs wear they start to leak. This bypass pushes mud around the swab, against the liners, greatly accelerating wear. By changing the swab at the first sign of bypass, I am able to get at least three sets of swabs before I have to change liners. This saves money.

Before I figured this out, I would sometimes have to run swabs to complete failure. (I was just a hand then, so it wasn’t my rig.) When I tore the pump down to put in swabs, lo-and-behold, the liners were cut so badly that they had to be changed too. That is false economy. Clean mud helps too. A desander will pay for itself in pump parts quicker than you think, and make a better hole to boot. Pump rods and packing last longer if they are washed and lubricated. In the oilfield, we use a petroleum-based lube, but that it not a good idea in the water well business. I generally use water and dish soap. Sometimes it tends to foam too much, so I add a few tablets of an over the counter, anti-gas product, like Di-Gel or Gas-Ex, to cut the foaming.

Maintenance on the gear end of your pump is important, too. Maintenance is WAY cheaper than repair. The first, and most important, thing is clean oil. On a duplex pump, there is a packing gland called an oil-stop on the gear end of the rod. This is often overlooked because the pump pumps just as well with a bad oil-stop. But as soon as the fluid end packing starts leaking, it pumps mud and abrasive sand into the gear end. This is a recipe for disaster. Eventually, all gear ends start knocking. The driller should notice this, and start planning. A lot of times, a driller will change the oil and go to a higher viscosity oil, thinking this will help cushion the knock. Wrong. Most smaller duplex pumps are splash lubricated. Thicker oil does not splash as well, and actually starves the bearings of lubrication and accelerates wear. I use 85W90 in my pumps. A thicker 90W140 weight wears them out a lot quicker. You can improve the “climbing” ability of the oil with an additive, like Lucas, if you want. That seems to help.

Outside the pump, but still an important part of the system, is the pop-off, or pressure relief valve. When you plug the bit, or your brother-in-law closes the discharge valve on a running pump, something has to give. Without a good, tested pop-off, the part that fails will be hard to fix, expensive and probably hurt somebody. Pop-off valve are easily overlooked. If you pump cement through your rig pump, it should be a standard part of the cleanup procedure. Remove the shear pin and wash through the valve. In the old days, these valves were made to use a common nail as the shear pin, but now nails come in so many grades that they are no longer a reliable tool. Rated shear pins are available for this. In no case should you ever run an Allen wrench! They are hardened steel and will hurt somebody or destroy your pump.

One last thing that helps pump maintenance is a good pulsation dampener. It should be close to the pump discharge, properly sized and drained after every job. Bet you never thought of that one. If your pump discharge goes straight to the standpipe, when you finish the job your standpipe is still full of fluid. Eventually the pulsation dampener will water-log and become useless. This is hard on the gear end of the pump. Open a valve that drains it at the end of every job. It’ll make your pump run smoother and longer.
