positive displacement mud pump in stock

Single Acting Triplex pumps come with three cylinders and are commonly used for various applications requiring low to medium flow rates including mud pumping, cement pumping, salt water disposal, descaling, high pressure pumping, Frac pumping and pipeline systems for the Oil & Gas, Agriculture, Mining, Municipal and Manufacturing sectors. We have new, used and rebuilt API 674 triplex pumps of all leading manufacturers like Union, Gaso, Emsco, Apex and Wheatley.

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.

Positive displacements pumps are generally used on drilling rigs to pump high pressure and high volume of drilling fluids throughout a drilling system. There are several reasons why the positive displacement mud pumps are used on the rigs.

The duplex pumps (Figure 1) have two cylinders with double acting. It means that pistons move back and take in drilling mud through open intake valve and other sides of the same pistons, the pistons push mud out through the discharge valves.

When the piston rod is moved forward, one of intake valves is lift to allow fluid to come in and one of the discharge valve is pushed up therefore the drilling mud is pumped out of the pump (Figure 2).

On the other hand, when the piston rod is moved backward drilling fluid is still pumped. The other intake and discharge valve will be opened (Figure 3).

The triplex pumps have three cylinders with single acting. The pistons are moved back and pull in drilling mud through open intake valves. When the pistons are moved forward and the drilling fluid is pushed out through open discharge valves.

On the contrary when the piston rods are moved backward, the intake valve are opened allowing drilling fluid coming into the pump (Figure 6). This video below shows how a triplex mud pump works.

Because each pump has power rating limit as 1600 hp, this will limit capability of pump. It means that you cannot pump at high rate and high pressure over what the pump can do. Use of a small liner will increase discharge pressure however the flow rate is reduces. Conversely, if a bigger liner is used to deliver more flow rate, maximum pump pressure will decrease.

As you can see, you can have 7500 psi with 4.5” liner but the maximum flow rate is only 297 GPM. If the biggest size of liner (7.25”) is used, the pump pressure is only 3200 psi.

Finally, we hope that this article would give you more understanding about the general idea of drilling mud pumps. Please feel free to add more comments.

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.

The mud motor is a progressive cavity positive displacement pump used in oil and gas drilling operations, fishing, etc. The global mud motor market is expected to reach USD 2028.46 million by 2026. The demand for mud motors is expected to grow due to increased fishing activities, demand for boating, and rising oil and drilling operations. In addition, demand for Horizontal Directional Drilling (HDD) and the development of unconventional hydrocarbons resources is expected to bolster the mud motor market.

A mud motor or a drilling motor is a positive displacement drilling motor that uses the drilling fluid’s hydraulic horsepower to drive the drill bit. Mud motors find extensive applications to reduce bearing load and provide an adjustable penetration rate, among other advantages.

It is expected that the global mud motor market will reach USD 2028.46 million by 2026. It is anticipated to register a CAGR of 4.7% during the forecast period (2021–2026).

Positive displacement and turbine are the two key motor types used in mud motors. Positive displacement motors (PDMs) find application in directional drilling projects and are primary components in bottom-hole drilling assemblies. Thus, the positive displacement segment is expected to register growth during the forecast period. Selection of the correct downhole motor is crucial in designing the buttonhole assembly (BHA) with mud motors to overcome cost-intensive challenges such as wellbore crookedness, string failures, and improper build rate. Technologically- and mechanically-advanced PDMs provide enhanced performance; for instance, a reduced-length positive displacement motor with an equidistant power section stator can provide superior motor performance and reliability at high operating temperatures.

Mud motors are available in several diameters; for the sake of this study, we have classified them as <100mm, 100mm–200mm, and >200mm. A motor’s power is inversely proportional to the square of its diameter also its torque is directly proportional to the cube of its diameter. Thus, the diameter is an important aspect in mud motor selection as it affects the motor’s torque and power.

Mud motors are classified into drilling and vertical. Lateral, curve, RSS, and air applications are included under the umbrella of vertical applications. With the applications of mud motors in metalworking, woodworking, and construction, the drilling segment is expected to gain significant traction and register a CAGR of 4.9% during the forecast period. According to Reports Monitor, the drilling segment was valued at USD 1,169.07 million in 2018, which is projected to grow to a value of USD 1,710.49 million by 2026.

Oil, natural gas, boating, and fishing are the key end-use sectors considered in this study on the mud motors market. Mud motors are used in drilling oil and natural gas wells. Thus, the demand for mud motors is expected to trail the growth of the oil and gas industry. According to the Organization of the Petroleum Exporting Countries (OPEC) global oil demand was pegged at 95.4 mb/d in 2016 and is projected to reach 102.3 mb/d by 2022. These figures underscore the potential that mud motors possess in the oil industry.

To better assess the global mud motors market, we have studied it across four key regions, namely North America, Europe, Asia Pacific, and Latin America, and the Middle East & Africa (LAMEA)

It signals the region’s vast potential in the mud motors market expected to remain strong in the coming years. The mud motors market was valued at USD 173.37 million in 20XX and is expected to grow to USD 279.50 million by 2026 with an anticipated CAGR of 5.1% during the forecast period.

Consolidation and restructuring of South-East Asia’s oil and gas industry, alongside increasing expenditure on upstream activities will accrue a substantial share for the region’s mud motors market. For instance, in Malaysia, Petroleum Nasional Berhad (Petronas), a state-owned corporation, has allocated USD 6.6 billion for upstream expenditure.

The Latin American mud pumps market is expected to witness significant growth in the coming years as the region possesses ultra-deepwater salt formations and undiscovered oil resources. For instance, it is estimated that over 100 exploration wells are anticipated to drill in Latin America outside Brazil in the next five years due to potential undiscovered oilfields in Guyana, Trinidad, and Colombia.

OK, all y’all air drillers just thumb on over to Porky’s column or something. This is for mud drillers. On second thought, I know a lot of you air guys drill about three mud wells a year, and consider it a hassle to rig up mud. So, maybe something I say will be interesting …

The mud pump is the heart of the circulating system, and mud is the blood circulating in the hole. I’ve talked about mud before and will again, but this month, let’s talk about the pump.

Historically, more wells, of every kind, have been drilled with duplex pumps than any other kind. They are simple and strong, and were designed in the days when things were meant to last. Most water well drillers use them. The drawbacks are size and weight. A pump big enough to do the job might be too big to fit on the rig, so some guys use skid-mounted pumps. They also take a fair amount of horsepower. If you were to break down the horsepower requirements of your rig, you would find out that the pump takes more power than the rotary and hoist combined. This is not a bad thing, since it does a lot of the work drilling. While duplex pumps generally make plenty of volume, one of the limiting factors is pressure. Handling the high pressures demanded by today’s oil well drilling required a pump so big and heavy as to be impractical. Some pretty smart guys came up with the triplex pump. It will pump the same — or more — volume in a smaller package, is easy to work on and will make insane pressure when needed. Some of the modern frack outfits run pumps that will pump all day long at 15,000 psi. Scary. Talk about burning some diesel.

The places that triplex pumps have in the shallow drilling market are in coring and air drilling. The volume needs are not as great. For instance, in hard rock coring, surface returns are not always even seen, and the fluid just keeps the diamonds cool. In air drilling, a small triplex is used to inject foam or other chemicals into the air line. It’s basically a glorified car wash pump. The generic name is Bean pump, but I think this just justifies a higher price. Kinda like getting the same burger at McDonald’s versus in a casino.

One of the reasons water well drillers don’t run triplex pumps, besides not needing insane pressure, is they require a positive suction head. In other words, they will not pick up out of the pit like a duplex. They require a centrifugal charging pump to feed them, and that is just another piece of equipment to haul and maintain.

This brings me to another thought: charging. I know a lot of drillers running duplex pumps that want to improve the efficiency of their pumps. Duplexes with a negative suction head generally run at about 85 percent efficiency. The easy way to improve the efficiency is to charge them, thus assuring a 100 percent efficiency. This works great, but almost every one of them, after doing all that work and rigging up a charging pump, tells me that their pump output doubled. Being the quiet, mild mannered type that I am, I don’t say “Bull,” but it is. A duplex pump is a positive displacement pump. That means that it can deliver no more than the displacement it was designed for. You can only fill the cylinder up until it is full. It won’t take any more. The one exception to this is when you are pumping at very low pressure. Then the charging pump will over run the duplex, float the valves and produce a lot more fluid. Might as well shut off the duplex and drill with the charging pump.

Another common pump used in the water well industry is the centrifugal. You see them mostly on air rigs that don’t use mud too often. They have their place, but are a different breed of cat. They are not positive displacement. Flow is a function of speed and horsepower up to the limits of the pump. After that, they just dead-head. With large diameter drill pipe they make a lot of mud, but after the hole gets deeper, friction losses — both inside and outside the drill pipe — build up. This means that the deeper you go, the less circulation you have. This slows the whole process. Positive displacement pumps don’t do this; they pump the same per stroke regardless of pressure. It just takes more horsepower. Also, displacement calculations like bottoms-up time and cement placement are just about impossible. One way to get around the limited pressure of centrifugal pumps is to run two of them in series. I’ve seen a few of these rig-ups and they work very well for large diameter drilling. They will make almost the same pressure as a big duplex for a lot less money. They are still variable displacement, but they roll so much fluid that it doesn’t seem to matter. And run at pretty reasonable depths, too: 300 to 400 psi at 400 gpm is not uncommon with two 3 x 4 centrifugal pumps in series.

I reckon there are pumps for every type of drilling. It is just a matter of using the right one correctly. I once drilled a 42-inch hole 842 feet deep with a 5½ x 8 duplex. Talk about long bottoms-up time … but we got the casing in with less than two feet of fill on bottom! Took time, but we got-er-done.

In 1990s, the trend of introducing new technologies for drilling high angle and horizontal wells and sidetracks continued. The introduction of these technologies, where PDM is one of the main elements of multifunctional complex technical, gained progress in oil and gas industry. In the last 10 years, new generation motors with improved technical and operational characteristics were introduced. Dr. Rene Moineau, a French engineer first invented and obtained several modified patents for a rotary type pump between 1930 and 1948.

The pumps he developed were extensively used in the world war planes as superchargers. In fact, Archimedes invented a pump that consisted of a spiral shaft which when turned by hand lifted water from lake. Moineau basically developed further Archimedean screw pump idea. The first commercial PDM was introduced to the petroleum industry in the late 1950s. Their use increased in the late 1960s for the directional drilling application. However, their use has accelerated greatly with the present coiled tubing drilling.

A mud pump is used as a high-pressure pump that circulates drilling mud on a drilling rig. Positive displacement pumps are commonly used in mud pumps. Regardless of the pump’s outlet pressure, positive displacement pumps can maintain a constant fluid flow rate.

Drilling mud pumps vary from duplex, triplex, and quintuplex pumps. An engine or a motor is used to power mud pump packages. Electric motors or diesel engines are commonly used on or near drilling rigs, depending on the fuel and energy available. We may use natural gas or other sources of fuel in some instances.

Drilling mud pumps are packaged in skid-type units, making them easier to disassemble and carry from one location to another. A charge pump is usually included in a mud pump system, which is used to boost the pressure of the fluid before it enters the main pump. Due to the high viscosity of the fluid, additional pressure on the mud pump’s entrance is frequently required to prevent cavitation.

Drilling, extraction, fracking all are heavy-duty processes that require heavy machinery. In any drilling project, all machinery is dependent on each other. If one machine breaks down, the whole chain will be affected. Therefore, the project management team must be ready for unforeseen events, with spare parts and replacements. One can replace the parts, but machinery can’t have replacements as that will be too costly. The mud pump is a crucial piece of machinery on the rig, and it will be handy to store mud pump spare parts.
