SB Series centrifugal pumps are distinguished by high efficiency, low energy consumption, several options, and a wide range of flow rates and pressures.


High efficiency
A precision-engineered pump and motor provide high efficiency and gentle product treatment. The robust design and tight tolerances together with the advanced impeller design minimize recirculation and ensure the efficient transfer of energy.

Optimal pump design
The impeller design ensures efficient and gentle handling of the product as it moves through the pump. This ensures product integrity and minimizes NPSHr ( Net Positive Suction Head required).

Low energy consumption
Making pump energy use more efficient presents huge potential for energy savings. The optimized pump design and premium motor of our centrifugal pumps often deliver greater energy efficiency than similar premium pumps and up to 50% compared to similar mid-range pumps.

SB series centrifugal pump is the ideal equipment to provide impetus for Desander 、Desilter and Jet Mud Mixer for solids control equipment. Centrifugal pump including single stage, multi stage, etc. divided by stage; including vertical type, horizontal type divided by stands type; including self-suction and non-self suction divided by suction model.


The centrifugal pumps also suited for drilling fluids processing. Using front and rear wear ring and balance holes to keep hydraulic balance. Single face mechanical seal or dual balanced cartridge seal can be used with cooling, washing or liquid-sealing system. Pipeline system is standardized by API. It is suitable to convey clean drilling mud liquid or drilling fluids with small amount of particles.

Anyhow, centrifugal pump almost used in every industry. Usually in drilling mud solids control, the centrifugal pump will be used as feeding pump to Shale shaker, Desander, Desilter, and decanter centrifuge.

A screw pump is a positive-displacement (PD) pump that use one or several screws to move fluids or solids along the screw(s) axis. A single screw rotates in a cylindrical cavity, thereby moving the material along the screw’s spindle. This ancient construction is still used in many low-tech applications, such as irrigation systems and in agricultural machinery for transporting grain and other solids.

mono pumps

Screw Pump is also used to feed drilling fluids to decanter centrifuge since drilling fluids is pushed to proceed along axial direction evenly. Therefore, the inner flow speed is kept low, volume unchanged and pressure stable so that vortex and agitation are prevented. Screw Pump is useful for wet mud drilling waste management and cuttings transportation.


Charateristics of screw pumps

1.Screw pumps are compact structure, small volume and easy maintenance. Rotor and stator, as the wearing parts of this pump, are convenient to replace.
2.We can manufacture the screw pump according to client’s requirement, for example, stainless steel 304 or SS316L material, manual speed control, variable frequency drive or fix speed pump, flow rate various from 20m3/h to 90m3/h for various model decanter centrifuge.
3.The stator is made of elastomeric material,so it has particular advantages than other pump to transfer the fluids of high viscosity and hard suspended particles included.

DC Machinery screw mono pump is an ideal pump for drilling mud feeding to decanter centrifuge without shearing or agitating the drilling mud. Compared to centrifugal pumps, screw pumps can move drilling mud axially without turbulence. Any interests please contact DC Solid control.

Submersible Slurry Pump have vertical single stage and single suction system overhung structure, adopt wear-resistant alloy material, convey medium with high concentration particle. It mainly composes of bearing housing, supporting, intermediate pipe connecting the pump hydraulic components.


Working process of slurry pumps

The liquid is discharged out from the drain pipe parts; pump impeller is for semi-shrouded with the agitating vane on the vane extended. The main characteristic of the slurry pump is that shaft parts of underwater pump are rigid enough. The impeller and pump shell have no bearings or shaft seal, which can convey larger medium of solids particles.


Features & Benefits of Submersible Slurry Pump

1. Shaft seal is not adapted, the medium with dense solids can also be transported.
2. Vertical motor is installed on the motor base, connected to the pump by coupling.
3. Using the power step-down, to ensure the slurry is not easy to leak.
4. Flow passage component of pump uses high hard alloy, the material has the advantages of high wear resistance, corrosion resistance, shock resistance and long
service life.

Drilling fluid pump is one special pump in centrifugal pump. We also call it as sand pump. It is mainly used to transfer drilling flfuid for desander, desilter, and provide sufficient power for mixing drilling fluid.Many hydraulic systems employ centrifugal pumps to move fluid through a piping system. These pumps all rely on centrifugal force as the fundamental principle by which they operate.


The centrifugal pump designs have proved to be among the best for handling abrasive cements and drilling fluids. They are available in wear-resistant materials compatible with the diverse applications of the oil and gas industry. The centrifugal pumps are available from a few gallons per minute to over two thousands five hundred gallons per minute. When downtime is critical, it is good to know that the centrifugal pump is dimensionally interchangeable with most centrifugal mud pumps in service today.

On occasion, the discharge of the centrifugal pump is pointed straight up. In these circumstances, the liquid is pumped up, but only to a predetermined height. This height is called the shut off head and is limited by the diameter of the pump’s impeller and the rotational speed of the pump itself.

Centrifugal pump

Another important issue for centrifugal pump is the seal. Commonly the mechanical seal will be considered better than oil rope seal, etc. Presently, the mechanical seal is more suitable for centrifugal pump used in solids control industry.

DCSB Series centrifugal pump mainly used in drilling fluids solids control system to feed materials according to clients’ctual working condition, detailed requirements, also other customized services for special demand.
