Centrifugal pumps are widely used in the entire drilling mud system. Through the comprehensive solid control system, it is utilized as a trip pump, sand removal pump, mud removal pump, mixing pump, charging pump, and more. AIPU provides a complete range of centrifugal pump for drilling mud systems.

In this article, we will explore the main features and advantages of using AIPU centrifugal pump.

What is the centrifugal pumps?

Moreover, the centrifugal pump converts the rotational kinetic energy into hydraulic energy. Typically, either an engine or an electric motor is the source of this rotational energy. Aipu supply pumps driven by 10HP to 100HP, which are popular in drilling mud process. Specifically, our pumps come in sizes such as 3x2, 4x3, 5x4, 6x5, and 8x6. It is important to note that these pumps will exhibit varying performance characteristics depending on factors such as power, voltage, and frequency.

What industries use centrifugal pumps?

Water and wastewater treatment: Water treatment plants extensively utilize centrifugal pump in processes such as pumping water from wells, transporting water within the facility, and distributing treated water to consumers. Wastewater treatment plants utilize centrifugal pumps for sewage pumping and handling sludge as well.

Oil and gas:Additionally, the oil and gas industry heavily relies on centrifugal pumps for transferring crude oil, boosting pipelines, hydraulic fracturing, and offshore drilling. Their ability to maintain consistent fluid flow rates throughout the production process further shows their importance.

Mining and mineral processing: Sure, centrifugal pumps extensively use in mining operations for various purposes such as dewatering mines, handling slurries, and transferring water or chemicals for mineral processing. Their robust construction enables them to handle abrasive and solid-laden fluids encountered in mining operations.

In addition to the above fields, various industries widely use centrifugal pump in agriculture, construction, pulp and paper, ships, and other sectors.

Features of AIPU centrifugal pumps

• Durable mechanical seal made of tungsten carbide alloy.
• FAG, SKF or other top brand bearings.
• SOG oil seal.
• Interchangeable with a famous pump.
• Less maintenance cost.
• Compact and small footprint

Centrifugal pumps is the equipment used to transfer drilling mud between equipment and tank. There are a few important pieces of information to determine in order to select correct pump size for rig operation.

Furthermore, please always refer to pump manufacturer's operation manual for pumps curve.

Centrifugal pumps and hydrocyclone location

Hydrocyclones should be set or mounted after primary shaker. Centrifugal pump transfer drilling mud from shaker tank or sand trap compartment to cones. Centrifugal pumps should be installed as closed to fluid scources as possible to shorten the distance, decrease the suction resistance. The pump feeding the hydrocyclones operates best with flooded suction. If possible, please mount the hydrocyclone pump below normal operating mud level in the pit. Otherwise, maintain suction whit as little lift as possible using a check valve or foot valve in the suction line.

Improper operation on pump

If the pump impeller selected not correctly, the pressure at feed manifold will be too low. And the pump pressure will lead un-efficient separation. We need to ensure pump has an impeller size rated to supply 75-90ft of head. Ensure location of feed manifold is above the mud level. Ensure accurate speed is provided to the pump.

Moreover, the feed pressure should be at least 30PSI, Preferably 35 PSI. This will request user and operator refer to performance curve for better correct selection. Usually, to achieve enough pressure head we'll consider the flow rate. Discharge rate should be 1.25 times of whole drilling mud flow rate

Pump failure and troubleshooting

If we find head decrease or flow rate decrease. There may be big particles block the suction line and impeller flow line or impeller speed decrease. We need to clean out the block and keep pump operated under rated condition

When there is leakage, the oil seal may be seriously abraded. Or there is serious abrasion on anti-abrasive shaft sleeve. Mechanical seal may fail. Please check the concerned parts and replace them

Please contact your supplier or manufacturer on some difficult failures. Aipu will be right here waiting for your call on any problem

Centrifugal pump is also referred to sand pump in China. Please contact Aipu solids control for high quality pump at lower cost in shortest delivery. Please find more information on oilfield centrifugal pump

Centrifugal pump definition and general information

Machine for moving fluid by spinning it using a rotating impeller in a casing with a central inlet and a tangential outlet

Such type pump commonly used in the handling and mixing of oilfield fluids. The rotary motion of a profiled impeller in combination with a shaped pump housing or volute applies centrifugal force to discharge fluids from the pump. Oilfield centrifugal pumps generally operate most efficiently in high-volume, low-output-pressure conditions. Unlike a positive-displacement pump, the flow from centrifugal pumps can be controlled easily, even allowing flow to be completely closed off using valves on the pump discharge manifold while the pump is running. This pump is also known as a "C pump."

Tips of oilfield centrifugal pump operation:

The path of the fluid is an increasing spiral from the inlet at the centre to the outlet, tangent to the impeller annulus.

Oilfield centrifugal pump

In the annular space between the impeller vane tips and the casing wall, the fluid velocity is roughly the same as that of the impeller vane tips. Power from the motor is used to accelerate the fluid entering the inlet up to the speed of the fluid in the annulus. Some of the motor power is expended as friction of the fluid in the casing and impeller.

These centrifugal pumps are developed and fabricated as supporting pumps based on requirement of transferring oil & gas drilling fluid. Centrifugal pump adopt the axial sucking structure and all the hydraulic components are wear proof cast iron, which is suitable for delivering the corrosive liquids with suspended particles in well drilling.

SB centrifugal pumps are characteristic of abrasion resistance, smooth and stable running, reliable sealing, long service life and convenient maintenance. Those pumps have been used for land and offshore drilling platforms in more than 20 countries over the world.

Clockwise pumps and anti-clockwise pumps are available.

Centrifugal pumps can be designed as clockwise or anti-clockwise. But they can't be fabricated both clockwise and anti-clockwise.

Mechanical seal and compound seal are available. The compound seal adopts auxiliary impeller, special oil seal and packing seal. Main seal of mechanical seal is mechanical seal with a long service life, auxiliary seal of machine seal is packing seal to prevent occurrence of accidents.

Shaft seals are lubricated with grease and bearings are lubricated with machine oil and grease since bearing covers at two ends of bearings are equipped with grease injectors. Both inlet flanges and outlet flanges for centrifugal pump are with two series standard dimensions.

Centrifugal pump are widely used in oilfield drilling equipment and drilling mud equipment like shale shakers, desanders desilters etc. Welcome to consult us for oilfield centrifugal pump.
