how many kwh does a mud pump use for sale

A mud pump is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi (52,000 kPa)) down the drill string and back up the annulus. A duplex mud pump is an important part of the equipment used for oil well drilling.

Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. Two later developments are the hex pump with six vertical pistons/plungers, and various quintuplex’s with five horizontal piston/plungers. The advantages that Duplex mud pumps have over convention triplex pumps is a lower mud noise which assists with better Measurement while drilling and Logging while drilling decoding.

Use duplex mud pumps to make sure that the circulation of the mud being drilled or the supply of liquid reaches the bottom of the well from the mud cleaning system. Despite being older technology than the triplex mud pump, the duplex mud pumps can use either electricity or diesel, and maintenance is easy due to their binocular floating seals and safety valves.

A mud pump is composed of many parts including mud pump liner, mud pump piston, modules, hydraulic seat pullers, and other parts. Parts of a mud pump:housing itself

Duplex pumps are used to provide a secondary means of fuel transfer in the event of a failure of the primary pump. Each pump in a duplex set is sized to meet the full flow requirements of the system. Pump controllers can be set for any of the following common operating modes:Lead / Lag (Primary / Secondary): The lead (primary) pump is selected by the user and the lag (secondary pump operates when a failure of the primary pump is detected.

Alternating: Operates per Lead / Lag (Primary / Secondary) except that the operating pump and lead / lag status alternate on consecutive starts. A variation is to alternate the pumps based on the operating time (hour meter) of the lead pump.

Triplex mud pump – We recommend the triplex mud pump for drilling applications that require a high pump pressure. One of the most common applications for a triplex mud pump is oil drilling, and it works by decreasing the volume of the working fluid being discharged to generate enough pressure to produce the flow.

A triplex mud pump comes with three pistons, where the middle piston is the one that generates more pressure to a crankshaft. However, be careful of high piston load, which can cause the excessive application of pressure that can lead to crankshaft failing or cracking. Be sure to explore our range of triplex mud pumps for sale here.

Quintuplex mud pump – These mud pumps are used to pump fluid during drilling operations, and they work as a continuous duty return piston. Their external bearings aid in the crankshaft’s support to ensure the proper function of the five eccentric sheaves.

Duplex mud pump – Use duplex mud pumps to make sure that the circulation of the mud being drilled or the supply of liquid reaches the bottom of the well from the mud cleaning system. Despite being older technology than the triplex mud pump, the duplex pumps can use either electricity or diesel, and maintenance is easy due to their binocular floating seals and safety valves.

A mud pump or drilling mud pump is used to circulate drilling mud on a drilling rig at high pressure. The mud is circulated down through the drill string, and back through the annulus at high pressures. Mud pumps are typically positive displacement pumps, otherwise known as reciprocating pumps. Mud pumps are ideal wherever a lot of fluid needs to be pumped under high pressure. They are considered an essential part of most oil well drilling rigs. Mud pumps can deliver high concentration and high viscosity slurry in a stable flow, making them adaptable to many uses.

Mud pumps are special-purpose pumps, particularly used for moving and circulating drilling fluids and other similar fluids in several applications such as mining and onshore and offshore oil & gas. Mud pumps are a piston/plunger cylinder systems that are used to transfer fluids at substantially high pressures. These pumps are operated in rugged and hostile environments and thus, are bulky and robust. These pumps can draw power from various sources. However, electricity and diesel are widely used sources. Diesel-driven mud pumps are well suited for remote and isolated applications where electricity is not continuously available. These pumps have two major sub-assemblies namely fluid and power ends.  The power end consumes power and drives the fluid end to pump the mud. The mud pump market is largely driven by the rising demand for oil & gas.

COVID-19 pandemic has shut-down the production of various products in the  mud pumps industry, mainly owing to the prolonged lockdown in major global countries. This has hampered the growth of mud pumps market  significantly from last few months, as is likely to continue during 2020.

COVID-19 has already affected the sales of equipment and machinery in the first quarter of 2020 and is likely to cause a negative impact on the market growth throughout the year.

The major demand for equipment and machinery was previously noticed from giant manufacturing countries including the U.S., Germany, Italy, the UK, and China, which is badly affected by the spread of coronavirus, thereby halting the demand for equipment and machinery.

Further, potential impact of the lockdown is currently vague and financial recovery of companies is totally based on its cash reserves. Equipment and machinery companies can afford a full lockdown only for a few months, after which the players would have to modify their investment plans.

Equipment and machinery manufacturers must focus on protecting their workforce, operations, and supply chains to respond toward immediate crises and find new ways of working after COVID-19

A mud pump has its use in drilling fluids, mining and various purpose like that and its increase in demand for such purpose is the  factor that drives its growth.increased demand for directional and horizonal drilling

The main drivers for the growth of this market are the increased demand for directional and horizonal drilling, higher pressure handling capabilities, and a number of new oil discoveries. The global rise in demand for energy boosts the global mud pumps as according to its immense use in  market. However, high cost of drilling, environmental risks, and changing government regulations for energy and power may hinder the growth of the market.Innovation in technology

Innovation in technology is the key for further growth for example, MTeq uses Energy Recovery’s Pressure exchanger technology in the drilling industry, as the ultimate engineered solution to increase productivity and reduce operating costs in pumping process by rerouting rough fluids away from high-pressure pumps, which helps reduce the cost of maintenance for operators. As there is increase in technology , so these kind of new innovations in traditional ways that eases the work and reduce the difficulties  becomes the factor to increase the growth of market.

Oil well drilling depends on many equipment and drilling rig mud pumps form an intrinsic part of operations. Reciprocating pumps that basically circulate mud, the drilling rig mud pumps offer continuous service to contractors with robust and rugged build. At Waters International, Inc our mission of featuring only the very best equipment on our site continues, with satisfied customers vouching for the build quality and performance of drilling rig mud pumps that we put up on offer. Here is a brief outline on the different types that are available in the market.

Triplex mud pump – At Waters International, Inc we have always believed in offering the right suggestions to clients. Hence, for drilling applications that require very high pump pressures, the triplex mud pump would be the most suitable. The most commonly used applications of triplex mud pumps are oil drilling, where it works by reducing the volume of the working fluid so as to generate adequate pressure for the purpose of producing the flow.  The triplex mud pump comprises three pistons, and the middle piston generates more pressure to a crankshaft. But, operators need to be cautious of high piston load, where the application of disproportionate pressure can result in the failure of the crankshaft.

Quintuplex mud pumps – Quintuplex mud pumps are typically used in operations where the fluid needs to be pumped during drilling operations. The pumps function in what is called as continuous duty return piston mode.  By virtue of being a quintuplex or five sheave models, the pump requires crankshaft support, which is provided by external bearings.

Duplex mud pump – Duplex mud pumps are generally used by contractors and operators to facilitate the circulation of mud that is drilled. The supply of liquid needs to reach the bottom of the well from its source, viz., the mud cleaning system. Duplex mud pumps are considered as technology that is old, however, the feature of the pumps that can work on either electricity or diesel, makes it a good choice. At Waters International, Inc we have always looked at equipment that require less maintenance and this fits the bill as one that demands the least maintenance.

Mud pump is one of the most critical equipment on the rig; therefore personnel on the rig must have good understanding about it. We’ve tried to find the good training about it but it is very difficult to find until we’ve seen this VDO training and it is a fantastic VDO training about the basic of mud pumps used in the oilfield. Total length of this VDO is about thirteen minutes and it is worth to watch it. You will learn about it so quickly. Additionally, we also add the full detailed transcripts which will acceleate the learning curve of learners.

Powerful mud pumps pick up mud from the suction tank and circulate the mud down hole, out the bit and back to the surface. Although rigs usually have two mud pumps and sometimes three or four, normally they use only one at a time. The others are mainly used as backup just in case one fails. Sometimes however the rig crew may compound the pumps, that is, they may use three or four pumps at the same time to move large volumes of mud when required.

Rigs use one of two types of mud pumps, Triplex pumps or Duplex pumps. Triplex pumps have three pistons that move back-and-forth in liners. Duplex pumps have two pistons move back and forth in liners.

Triplex pumps have many advantages they weight 30% less than a duplex of equal horsepower or kilowatts. The lighter weight parts are easier to handle and therefore easier to maintain. The other advantages include;

• One of the more important advantages of triplex over duplex pumps, is that they can move large volumes of mud at the higher pressure is required for modern deep hole drilling.

Triplex pumps are gradually phasing out duplex units. In a triplex pump, the pistons discharge mud only when they move forward in the liner. Then, when they moved back they draw in mud on the same side of the piston. Because of this, they are also called “single acting.” Single acting triplex pumps, pump mud at a relatively high speeds. Input horsepower ranges from 220 to 2200 or 164 to 1641 kW. Large pumps can pump over 1100 gallons per minute, over 4000 L per minute. Some big pumps have a maximum rated pressure of over 7000 psi over 50,000 kPa with 5 inch/127 mm liners.

Here is a schematic of a triplex pump. It has three pistons each moving in its own liner. It also has three intake valves and three discharge valves. It also has a pulsation dampener in the discharge line.

Look at the piston at left, it has just completed pushing mud out of the liner through the open discharge valve. The piston is at its maximum point of forward travel. The other two pistons are at other positions in their travel and are also pumping mud. But for now, concentrate on the left one to understand how the pump works. The left piston has completed its backstroke drawing in mud through the open intake valve. As the piston moved back it instead of the intake valve off its seat and drew mud in. A strong spring holds the discharge above closed. The left piston has moved forward pushing mud through the now open discharge valve. A strong spring holds the intake valve closed. They left piston has completed its forward stroke they form the length of the liner completely discharging the mud from it. All three pistons work together to keep a continuous flow of mud coming into and out of the pump.

Crewmembers can change the liners and pistons. Not only can they replace worn out ones, they can also install different sizes. Generally they use large liners and pistons when the pump needs to move large volumes of mud at relatively low pressure. They use a small liners and pistons when the pump needs to move smaller volumes of mud at a relatively high pressure.

In a duplex pump, pistons discharge mud on one side of the piston and at the same time, take in mud on the other side. Notice the top piston and the liner. As the piston moves forward, it discharges mud on one side as it draws in mud on the other then as it moves back, it discharges mud on the other side and draws in mud on the side it at had earlier discharge it. Duplex pumps are therefore double acting.

Double acting pumps move more mud on a single stroke than a triplex. However, because of they are double acting they have a seal around the piston rod. This seal keeps them from moving as fast as a triplex. Input horsepower ranges from 190 to 1790 hp or from 142 to 1335 kW. The largest pumps maximum rated working pressure is about 5000 psi, almost 35,000 kPa with 6 inch/152 mm linings.

A mud pump has a fluid end, our end and intake and the discharge valves. The fluid end of the pump contains the pistons with liners which take in or discharge the fluid or mud. The pump pistons draw in mud through the intake valves and push mud out through the discharge valves.

The power end houses the large crankshaft and gear assembly that moves the piston assemblies on the fluid end. Pumps are powered by a pump motor. Large modern diesel/electric rigs use powerful electric motors to drive the pump. Mechanical rigs use chain drives or power bands (belts) from the rig’s engines and compounds to drive the pump.

A pulsation dampener connected to the pump’s discharge line smooths out surges created by the pistons as they discharge mud. This is a standard bladder type dampener. The bladder and the dampener body, separates pressurized nitrogen gas above from mud below. The bladder is made from synthetic rubber and is flexible. When mud discharge pressure presses against the bottom of the bladder, nitrogen pressure above the bladder resists it. This resistance smoothes out the surges of mud leaving the pump.

Here is the latest type of pulsation dampener, it does not have a bladder. It is a sphere about 4 feet or 1.2 m in diameter. It is built into the mud pump’s discharge line. The large chamber is form of mud. It has no moving parts so it does not need maintenance. The mud in the large volume sphere, absorbs this surges of mud leaving the pump.

A suction dampener smooths out the flow of mud entering into the pump. Crewmembers mount it on the triplex mud pump’s suction line. Inside the steel chamber is a air charged rubber bladder or diaphragm. The crew charges of the bladder about 10 to 15 psi/50 to 100 kPa. The suction dampener absorbs surges in the mud pump’s suction line caused by the fast-moving pump pistons. The pistons, constantly starts and stops the mud’s flow through the pump. At the other end of the charging line a suction pumps sends a smooth flow of mud to the pump’s intake. When the smooth flow meets the surging flow, the impact is absorbed by the dampener.

Workers always install a discharge pressure relief valve. They install it on the pump’s discharge side in or near the discharge line. If for some reason too much pressure builds up in the discharge line, perhaps the drill bit or annulus gets plugged, the relief valve opens. That opened above protects the mud pump and system damage from over pressure.

Some rig owners install a suction line relief valve. They install it on top of the suction line near the suction dampener. They mount it on top so that it won’t clog up with mud when the system is shut down. A suction relief valve protects the charging pump and the suction line dampener. A suction relief valve usually has a 2 inch or 50 mm seat opening. The installer normally adjusts it to 70 psi or 500 kPa relieving pressure. If both the suction and the discharged valves failed on the same side of the pump, high back flow or a pressure surge would occur. The high backflow could damage the charging pump or the suction line dampener. The discharge line is a high-pressure line through which the pump moves mud. From the discharge line, the mud goes through the stand pipe and rotary hose to the drill string equipment.

To help curb climate change, President Biden has set a goal of lowering U.S. greenhouse gas emissions 50%-52% below 2005 levels by 2030. Meeting this target will require rapidly converting as many fossil fuel-powered activities to electricity as possible, and then generating that electricity from low-carbon and carbon-free sources such as wind, solar, hydropower and nuclear energy.

The buildings that people live and work in consume substantial amounts of energy. In 2019, commercial and residential buildings accounted for more than one-seventh of U.S. greenhouse gas emissions. New heating and cooling strategies are an important piece of the puzzle.

Fortunately, there’s an existing technology that can do this: electric heat pumps that are three to four times more efficient than furnaces. These devices heat homes in winter and cool them in summer by moving heat in and out of buildings, rather than by burning fossil fuel.

As a scientist focusing on renewable and clean energy, I study energy use in housing and what slowing climate change means for industrialized and developing countries. I see powering buildings with clean, renewable electricity as an essential strategy that also will save consumers money.

Heat pumps draw in air from the outside and use the difference in temperature between indoor and outdoor air to heat buildings. Many also provide cooling, using nearly the same mechanism.

Most heating systems in the U.S. use forced-air furnaces that run on natural gas or electricity, or in some cases heating oil. To heat the building, the systems burn fuel or use electricity to heat up air, and then blow the warm air through ducts into individual rooms.

A heat pump works more like a refrigerator, which extracts energy from the air inside the fridge and dumps that energy into the room, leaving the inside cooler. To heat a building, a heat pump extracts energy from outdoor air or from the ground and converts it to heat for the house.

Here’s how it works: Extremely cold fluid circulates through coils of tubing in the heat pump’s outdoor unit. That fluid absorbs energy in the form of heat from the surrounding air, which is warmer than the fluid. The fluid vaporizes and then circulates into a compressor. Compressing any gas heats it up, so this process generates heat. Then the vapor moves through coils of tubing in the indoor unit of the heat pump, heating the building.

In summer, the heat pump runs in reverse and takes energy from the room and moves that heat outdoors, even though it’s hotter outside – basically, functioning like a bigger version of a refrigerator.

Heat pumps require some electricity to run, but it’s a relatively small amount. Modern heat pump systems can transfer three or four times more thermal energy in the form of heat than they consume in electrical energy to do this work – and that the homeowner pays for.

In contrast, converting energy from one form to another, as conventional heating systems do, always wastes some of it. That’s true for burning oil or gas to heat air in a furnace, or using electric heaters to heat air – although in that case, the waste occurs when the electricity is generated. About two-thirds of the energy used to produce electricity at a power plant is lost in the process.

Retrofitting residences and commercial buildings with heat pumps increases heating efficiency. When combined with a switch from fossil fuels to renewables, it further lowers energy use and carbon emissions.

Growing restrictions on fossil fuel use and proactive policies are driving sales of heat pumps in the U.S. and internationally. Heat pumps are currently used in 5% of heating systems worldwide, a share that will need to increase to one-third by 2030 and much higher after to reach net-zero emissions by 2050.

In warmer areas with relatively low heating demands, heat pumps are cheaper to run than furnaces. Tax credits, utility rebates or other subsidies may also provide incentives to help with up-front costs, including federal incentives reinstated by the Biden administration.

In extremely cold climates, these systems have an extra internal heater to help out. This unit is not as efficient, and can significantly run up electric bills. People who live in cold locations may want to consider geothermal heat pumps as an alternative.

These systems leverage the fact that ground temperature is warmer than the air in winter. Geothermal systems collect warmth from the earth and use the same fluid and compressor technology as air source heat pumps to transfer heat into buildings. They cost more, since installing them involves excavation to bury tubing below ground, but they also reduce electricity use.

New, smaller “mini-split” heat pump systems work well in all but the coldest climates. Instead of requiring ducts to move air through buildings, these systems connect to wall-mounted units that heat or cool individual rooms. They are easy to install and can be selectively used in individual apartments, which makes retrofitting large buildings easier.

Even with the best heating and cooling systems, installing proper insulation and sealing building leaks are key to reducing energy use. You can also experiment with your thermostat to see how little you can heat or cool your home while keeping everyone in it comfortable.

For help figuring out whether a heat pump can work for you, one good source of information is your electricity provider. Many utilities offer home energy audits that can identify cost-effective ways to make your home more energy-efficient. Other good sources include the U.S. Department of Energy and the American Council for an Energy Efficient Economy. As the push to electrify society gains speed, heat pumps are ready to play a central role.

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters reduce the amount of airflow and significantly reduce a system"s efficiency. In addition, when airflow is obstructed, air can bypass the filter and deposit dirt directly into the evaporator coil and  impair the coil"s heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner"s energy consumption by 5% to 15%.

For central air conditioners, filters are generally located somewhere along the return duct"s length. Common filter locations are in walls, ceilings, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that faces into the room.

Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system"s filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.

Pumps as turbines (PAT) is a known concept of using excess flow and pressure to run a pump in reverse to generate electricity. PAT has twin modes to enable them to pump as well as generate electricity. When a pump is used in turbine mode it is typically only 3-5% less efficient than when operating as a pump.

Pump as turbines can be used as an alternative to not only turbines which are more difficult to operate and maintain than pumps but as a viable alternative to pressure reducing valves. Payback can be as little as 3 years whereas turbines which can take as long as 15 years as well as being more complicated to service.

Pumps as turbines are a viable alternative to pressure reducing valves and traditional turbines. If you have excess pressure in your pipeline or a river and are looking at ways to recover energy please speak to us so we can ascertain whether a pump as turbine is a viable option for you.

Industrial pumps are essential devices required in every phase of oil and gas operations. Basically, they help transfer process fluids from one point to another.

For example, a pump can be used to transfer crude oil from a storage tank to a pipeline and mud pumps are used to circulate drilling mud into the annulus of a drill bit and back to a storage tank for re-purification.

In oil and gas operations, process fluids can range from easy to difficult.  Depending on the nature of the substance you want to transfer and your required flow rate, you’ll need a suitable pump for your needs.

Various types of industrial pumps are utilized for fluid transfer in the oil and gas industry. Pumps used in O&G can be classified based on their design and construction and generally fall into 6 major categories:

Centrifugal pumps are the most common types of pumps used in the oil and gas industry. Centrifugal pumps use centrifugal force through the rotation of the pump impeller to draw fluid into the intake of the pump and force it through the discharge section via centrifugal force. The flow through the pump is controlled by discharge flow control valves.

Single stage centrifugal pumps are primarily used for transferring low-viscosity fluids that require high flow rates. They are typically used as part of a larger pump network comprising other centrifugal pumps like horizontal multistage pump units for crude oil shipping or water injection pumps used in secondary oil and gas recovery.

Plunger pumps are some of the most ubiquitous industrial pumps in the oil and gas industry. Plunger pumps use the reciprocating motion of plungers and pistons to pressurize fluid in an enclosed cylinder to a piping system. Plunger pumps are considered constant flow pumps since at a given speed, the flow rate is constant despite the system pressure. A relief valve is an essential part of any plunger pump discharge piping system to prevent overpressuring of the pump and piping system.

Plunger pumps require more frequent maintenance than centrifugal pumps due to the design of the moving parts. They also have a noisier operation than centrifugal pumps.

A progressive cavity pump is a type of positive displacement pump and is also known as an eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned. Progressive cavity pumps are used in high viscosity applications or if blending the of the pumped fluid is not desired.

Progressive cavity pumps are also considered constant flow pumps since at a given speed, the flow rate is relatively constant despite the system pressure. Flow slippage is normal at higher pressures. A relief valve is an essential part of any progressive cavity pump discharge piping system to prevent overpressuring of the pump and piping system.

Diaphragm pumps are one of the most versatile types of oil and gas pumps in the industry and transfer fluid through positive displacement with a valve and diaphragm. The working principle of this pump is that a decrease in volume causes an increase in pressure in a vacuum and vice versa.

Diaphragm pumps are suitable for high-volume fluid transfer operations in oil refineries. They also require much less maintenance than positive displacement pumps due to their fewer moving parts and less friction during operation and are available in compact designs.

On the downside, diaphragm pumps are susceptible to ‘winks’ – low-pressure conditions inside the system that slow down pumping operations. Fortunately, winks can be rectified by using a back-pressure regulator. For the same reason, they are not suitable for continuous or long-distance pumping operations as they generally don’t meet the high-pressure conditions required.

A gear pump uses the meshing of gears to pump fluid by displacement. Gear pumps are one of the most common types of positive displacement pumps for transferring industrial fluids.

Gear pumps are also widely used for chemical transfer applications for high viscosity fluids. There are two main variations: external gear pumps which use two external spur gears or timing gears that drive the internal gear set. The internal gears do not touch, so non-lubricating fluids can be pumped with external gear pumps. Internal gear pumps use a shaft driven drive gear to drive the internal mating gear. Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution.

Since the pumped fluid passes between the close gear tolerances, gear pumps are normally used for clean fluids. A relief valve is an essential component in the discharge piping system to protect the pump and piping from over pressurizing.

A metering pump moves a precise volume of liquid in a specified time period providing an accurate flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term “metering pump” is based on the application or use rather than the exact kind of pump used. Most metering pumps are simplex reciprocating pumps with a packed plunger or diaphragm liquid end. The diaphragm liquid end is preferred since the pumped fluid is sealed inside the diaphragm. No pumped liquid leaks to the atmosphere.
