What is a mud pump? A mud pump refers to a machine that transports mud or water and other flushing fluid into the borehole during drilling. Types of mud pumps are an important part of drilling equipment. In the commonly used positive circulation drilling, it is to send the surface flushing medium—clear water, mud, or polymer rinsing liquid to the bottom end of the drill bit through a high-pressure hose, faucet, and drill rod center hole under a certain pressure. Cool the drill bit, remove the cut debris and transport it to the surface.

The commonly used mud pump is a piston-type or a plunger type, and the crankshaft of the pump is driven by the power machine, and the crankshaft passes the crosshead to drive the piston or the plunger to reciprocate in the pump cylinder. Under the alternating action of the suction and discharge valves, the purpose of pumping and circulating the flushing liquid is achieved.

During operation, the power machine drives the main shaft and the crank that is fixed thereon by a transmission component such as a belt, a transmission shaft, and a gear. When the crank rotates counterclockwise from the horizontal position from left to right, the piston moves to the power end, the pressure in the liquid cylinder gradually decreases and a vacuum is formed, and the liquid in the suction pool is under the action of the liquid surface pressure, and the suction valve is opened to enter the liquid cylinder. Until the piston moves to the right stop. This working process is called the suction process of the pump.

After the crank completes the above suction process, it continues to rotate counterclockwise. At this time, the piston starts to move toward the hydraulic end (left side in the figure), and the liquid in the cylinder is squeezed. The pressure rises, the suction valve closes, and the discharge valve is closed. Top open, liquid enters the discharge pipe until the piston moves to the left stop. This process is called the pump discharge process. As the power machine continues to operate, the reciprocating pump continuously repeats the process of inhaling and discharging, and the liquid in the suction pool is continuously sent to the bottom of the well through the discharge pipe.

Mud Pump Pulsation Dampener is usually installed on the discharge line to reduce the fluctuation of pressure and displacement of the drilling mud pump.

Mud Pump Pulsation Dampener is a pneumatic device built into the outflow line of each UUD pump to dampen the pressure fluctuations resulting from the action of the pump. Although presented as a surge tank, this device is really a device that can be tuned to greatly diminish the output pulsations transmitted downstream from the mud pump. Unfortunately, the effectiveness of the pulsation dampener is a function of both output pump pressure and frequency of the pump pulsations.

Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport. Mud pumps are mainly used for drilling, pharmaceutical, brewing, paper, and other industries, which used to transport suspension.

The slurry pump is mainly used in the mining industry, its wear resistance is strong. So It conveys slurry that containing slag, but it can conveys mud. The mud pump is usually made of cast iron, the wear resistance of the pump is low. So the mud pumps often used for conveying mud or slurry containing suspended particles. When the slurry pump working, pump parts are easy to be impacted, wear, and corrosion, etc. Therefore, the liner of the slurry pump uses wear-resistant material, such as high chromium alloy, rubber. The wear-resistant materials can effectively reduce the wear parts of the pump. So most of the slurry pump is a wear-resistant slurry pump in the current market.

The mud pump is the motor driving the piston move through the link mechanism. Then causes the change of the volume of the sealed chamber of the mud pump. and the pressure difference between inside and outside of the pump change. Finally, the process of absorbing water and draining water is complete. When slurry pump working, which is the motor drives the impeller rotation. That is the impeller on the slurry work which increases the kinetic energy of the slurry. At the same time, the slurry flows to the edge of the impeller due to inertia and is discharged from the discharge pipe at a high speed.

The Mud pumps need to be equipped with auxiliary equipment, but slurry pumps not. They often need to use with high-pressure water pump when mud pump working. The high-pressure pump sent the water that larger than the mud pump pressure to the leakproof packing. Then protect the packing. Otherwise, it is easy to make the seal part wear. But the wear-resistant slurry pumps can complete the transportation work independently, which not need to equip other auxiliary equipment.

In a word, the wear-resistant properties of the slurry pumps are stronger, and the ability to convey particles is also stronger. Generally, the capacity of the slurry pump is larger than the mud pump, which is mainly used for coal and metal ore washing. The mud pumps are more suitable for abrasive slurry is not very strong.

Single Screw Pumps are a type of rotary Positive Displacement Pumps. These pumps are the best choice for transfer of liquids requiring smooth and non-pulsating flow. These pumps are known for their high suction ability. Single screw pumps cater to a number of industries including shipping, chemical, ceramic, paper, waste water, paint, oil & gas and many more. These pumps can efficiently handle the transfer of abrasive and non-abrasive liquids, with and without solid particles such as sewage, sludge, bilge and foods such as jelly, yeast and ketchup. These pumps offer very low life cycle cost. Also single screw pumps are non-clogging.

Single Screw Pumps are reversible. These pumps work on the principle of positive displacement. These pumps comprise of a single helix metallic rotor and double helix elastomer stator.  The liquid is pumped through suction port. As the rotor moves inside the stator, cavities are formed. The liquid moves along the cavities due to positive displacement and gets discharged from the discharge port of the pump.

Roto Pumps is a noted Progressive Cavity Pumps manufacturer. High Pressure Progressive Cavity Pumps are also known as Single Screw Pumps, these pumps have been built and designed to transfer liquids with different chemical properties and variable viscosities. These pumps can be customized as per the application requirement. These pumps function with the help of precision mechanized single external helix metallic rotor and double internal helix elastomer stator. The fluid gets transferred through the cavities formed by the turning of the rotor within the stator.

The working principle of these pumps involves the rotation of the single helix-shaped rotor within the stator. A sealing line is developed along the axis of the rotor owing to the positioning of the rotor and the stator, which upholds in both static and compelling conditions. Several cavities are formed along the suction and the discharge end of the pump by the rotation of the rotor. These cavities transfer the fluid within the pumps.

If a pump is located beneath the level of the liquid to be pumped, gravity and air pressure ensure that it is constantly filled with the liquid and there can be no ingress of air into the pump or suction line.

In many applications, a pump has to be placed above the level of the liquid, for example, when emptying an underground storage tank. At start-up, there will be air in the suction line and before the pump can discharge the liquid, this air must be evacuated or displaced. Pumps are optimised to move a particular liquid; evacuating a gas is a very different challenge.

Various methods can be used to get around this problem. A secondary pump can be used to evacuate the suction line. A non-return (foot) valve or evacuation tank can be used to stop fluid draining from the suction line when the pump is stopped. However, these solutions all involve extra equipment, piping and processes. Ideally, for these applications, a pump is required that can evacuate air from the suction side at startup before commencing its normal pumping mode. Such a pump is considered to be self-priming.

As a pump evacuates air from the suction side, liquid is forced into the suction line by the pressure of the surrounding air. This process can only continue until the head of liquid balances the local air pressure. With water, for example, it is theoretically possible for a perfectly efficient pump to self-prime to a height of only about 10m from its source. The precise limit is affected by altitude and temperature and will be different for other liquids.

In principle, all positive displacement pumps are self-priming. In particular, this includes rotary gear pumps (internal and external), lobe pumps, vane pumps and diaphragm pumps. A common feature of all positive displacement pumps is the use of close-tolerance parts to prevent fluid returning from the discharge to the suction side. Depending on the effectiveness of these seals created by these close-tolerance parts, a positive displacement pump is capable of venting air from its suction line to some extent. However, under dry running conditions, a pump may overheat and this can cause seal wear and pump failure.

With reciprocating pumps, there is also a danger of cavitation occurring at the point when liquid starts to enter the pump and there is a liquid/air mixture. Under these conditions, vapour bubbles form and expand on the suction side of the pump. Upon reaching the high pressure, discharge side of the pump, the bubbles collapse violently causing vibration and damage to the pumping elements.

For these reasons, it is important to refer to the manufacturer before using a positive displacement pump in an application where it must self-prime and, of necessity, be run dry for any period.

With centrifugal pumps, the pumping action is generated by the transfer of rotational energy from the impeller to the liquid. There are no seals between the suction and discharge sides of the pump. This means that centrifugal pumps are ineffective with gases and are not capable of evacuating air from a suction line when the liquid level is below that of the impeller. In such cases, the pump is said to be air-bound and there is a danger of overheating: generally, pumps rely on the pumped fluid to lubricate and cool the pump’s bearings.

However, with a few modifications to the basic design, a centrifugal pump can be self-priming. The impeller and volute casing is essentially surrounded by a tank so that it can always be immersed in a liquid sufficient to get the pump started and provide the pump with lubrication and cooling – provided the time taken to prime the pump is not excessive.

It is important that a self-priming centrifugal pump’s reservoir is filled correctly with liquid after installation. "Self-priming" in this context means that the pump has the ability to use liquid stored in its housing to generate a vacuum on the suction line. Even a ‘self-priming’ centrifugal pump will not operate when dry. With appropriate bearings and seals, a centrifugal pump can tolerate dry running for a limited time but this is not recommended for extended periods.

In its priming mode, the pump essentially acts as a liquid-ring pump. The rotating impeller generates a vacuum at the impeller’s ‘eye’ which draws air into the pump from the suction line. At the same time, it also creates a cylindrical ring of liquid on the inside of the pump casing. This effectively forms a gas-tight seal, stopping air returning from the discharge line to the suction line. Air bubbles are trapped in the liquid within the impeller’s vanes and transported to the discharge port. There, the air is expelled and the liquid returns under gravity to the reservoir in the pump housing.

Gradually, liquid rises up the suction line as it is evacuated. This process continues until liquid replaces all the air in the suction piping and the pump. At this stage, the normal pumping mode commences, and liquid is discharged.

When the pump is shut off, the design of the priming chamber (normally involving a ‘goose-neck’ on the suction piping) ensures that enough liquid is retained so that the pump can self-prime on the next occasion it is used. If a pump has not been used for a while, it is important to check for losses from the casing due to leaks or evaporation before starting it.

It is possible to use compressed air, instead of a liquid charge, to prime a pump. Compressed air is blown through a jet into a tapered tube to create a vacuum. Air from the pump casing and suction line is drawn in with the compressed air and vented. A check valve seals the discharge line, allowing liquid to enter the pump body. This method has the advantages that the potential for blockages is reduced (because there is no priming chamber) and the pump can be run dry safely.

The ability of a pump to self-prime can be affected by several factors. The discharge line must not be pressurised or blocked. With all types of pump, the suction line must be air-tight. If air continues to be drawn into the pump, the pressure is never reduced and fluid is not drawn up the suction line.

It is also important that the volume of the suction-side pipework is minimised to reduce the priming time. With excessive priming times, there is a danger that the liquid charge will evaporate before the pump is primed. The consequential dry-running may then cause damage to the pump.

In the case of centrifugal pumps, anything that affects the efficiency of the impeller will limit the self-priming ability. If the liquid contains any solids, debris may collect in the recirculation port, impeding the circulation of fluid and the generation of the liquid ring. Debris collecting on the impeller itself will reduce its ability to generate a low pressure region at the eye. Also, as a pump ages and succumbs to wear, the clearances between the impeller and volute case increase and the pump is less able to generate a low pressure zone. Internal clearances can also be affected by incorrect assembly after maintenance.

When pumping water in cold environments, it’s important, if the temperature may fall below freezing, to drain a pump or to provide some form of heating. Damage may occur if water freezes in the pump or pipework.

Self-priming pumps are necessary if a pump has to be located above the level of the liquid to be pumped. A self-priming pump must be capable of evacuating air from the suction line, thereby drawing liquid into the pump. When this has been achieved, the pump can revert to its normal pumping mode.

Most types of positive displacement pumps are self-priming but care must be taken to avoid overheating, seal wear or cavitation during the dry-running, priming phase. Centrifugal pumps can be modified to be self-priming with a surrounding ‘tank’ to retain some of the fluid. Before use, it is crucial that the pump is filled correctly and not allowed to run dry at any stage.

Progressive cavity pumps, also known as PC pumps, progressing cavity pumps, eccentric screw pump and mono pumps are a type of rotary positive displacement pump designed for the conveying of liquids and sludges from 1cst to 1Million. They handle not only viscous fluids and solids but also gassing or multiphase liquids containing gas slugs typical during crude oil extraction.

The volume of liquid pumped is proportional to speed providing a linear predictable pumping rate across a range of pressures. This technology delivers one of the highest flow and pressures available from a positive displacement pump being up to 600M³H and 48bar, with efficiency ranging from 55% to 75%. This technology is most suited for fluids more viscous than 5cst.

The design consists of a motor at the drive end which is connected to a gearbox as pc pumps operate at low rpm compared to centrifugal pumps. The output shaft from the gearbox connects to a rotor via a universal pin joint which rotates a metallic rotor within a rubber stator. Stators contain cavities, and the rotor pushes fluids through the cavities in a slow rotating fashion.

A pumps pressure generating ability will depend on the number of cavities within the pump, with high pressure designs often consisting of more than one stator and rotor. Each rotor will typically produce 6 bar enabling pressures up to 48 bar to be achieved through its modular design.

This design of pump is better suited for viscous lubricating fluids, which can contain solids. Short stator life can be experienced with abrasive slurries at which point a peristaltic pump can be a preferred option. Eccentric Screw Pumps viscosity handing is unrivalled, and they are usually specified when there are no other suitable options.

Stator designs consist of two types - equal and non-equal walled. Equal walled stators ensure a lower starting and running torque, lower pulsations and reduced power consumption, high volumetric pumping efficiency, and lower replacement costs. Materials are usually types of rubber being NBR, FKM but not PTFE meaning solvents cannot be handled.

·Oil & Gas – Cutting Transfer, Drilling Mud transfer and recovery, Separator Feed, Crude Oil Transfer, MOL (Main Oil line Pump), Multiphase transfer and injection in remote areas.

Low shear -Ensures gentle handling of the most difficult to pump fluids such as resins, viscous foods, oil and water emulsions without change in consistency to the liquid. They are often use in oily water separators as the design ensures oil droplets remain intact and was rated by SPE (Society of Petroleum Engineers) in Paper SPE18204 as the preferred pump to use for oil droplets which were disturbed the least during handling and a comparison of lobe, vane and screw technology.

Reversible – Units are reversible with reduced output pressure as standard meaning hoses can be emptied, or if blockages are encountered pump can be reversed to assist with clearing. It also enable the pump to be versatile for situations such as tanker loading and offloading.

Wide fluid handling capabilities –Designs can handle viscous liquids, large solids, abrasive materials, fibrous solids and gas slugs without issue making it one of the most versatile pumps available. This design has Unparalleled Viscosity handling viscosities from 1cst to 1Million means there are no comparable pumping technologies.

High Accuracy –Due to flow being directly proportional to pump speed, and due to its cavity design, it enables flows to be very predictable enabling it to be used in metering and dosing applications

Hopper Pump –A pump is fitted with a hopper of various designs, designed for viscous liquids, materials containing high amounts of dry matter, large solids requiring breaking up and materials which plasticise

Multiphase Design -Baseplate mounted unit for multiphase boosting, with accessories allowing pump to handle viscous oil, gas slugs, sand and water, with automatic remote operation.

Bridge Breaker –For the breaking up of large solids within dehydrated sludge. Motorised paddles rotate within the hopper ensuring particles are broken into sizes which can be accommodated by the pump preventing blockages

Motorised wheel – Feeding of liquids with high dry solid content and materials which plasticize into the main pump. When materials such as liquid mortar, resins, mud, blocks of fat, or butter are pumped they can plasticise meaning they change shape rather than break up. To ensure they are fed into the rotor and stator, a motorised wheel ensures materials are broken up when other technologies may mean materials clog.

Liquid injection port –Typically used for the biogas sector, this unit has a separate injection port for accepting liquid manure which is combined with materials in the inlet containing high dry solids content (such as digestate, straw, corn, grass, rye, vegetable and food waste ) ensuring pumpability.

PC Pump curves are different to a centrifugal curve as it is linear demonstrating the units ability to handle liquids of varying viscosities with little impact on pump performance, with the bottom axis being speed rather than flow as flow is proportional to speed. Unit speed is much lower than centrifugal, operating from as little as 50rpm

Not suitable for solventsAll metal parts means solvents can be transferred, although some designs may have bearings within liquids and should be avoidedAll metal parts means solvents can be pumped.
