Brief introduction on centrifugal pump

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; including common material centrifugal pump, stainless steel pump divided by wet parts material; including water pump, oil pump, slurry pump, etc. divided by process medium.

Centrifugal pump in various industry

Centrifugal pumps are commonly used to handle medium between -20℃~105℃, and even higher temperature medium of provided with cooling measures in case of needed. They are suitable for chemical, petroleum, metallurgy, electric power, papermaking, foodstuff,  pharmaceuticals, synthetic, etc. industry. They are featured by wide range of performance, high efficiency, superior standardization, easy maintenance, etc.        

 The Centrifugal pump is a centrifugal volute pump with  single stage, end suction and cantilever design .And the casing is sustained  with centerline, and with axial suction and radial discharge. 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.

Centrifugal pump in solids control

Moreover, the centrifugal pump used on pumping drilling mud to related equipments. There will be also customers require screw pump for decanter centrifuge drilling fluids feeding instead of common centrifugal pump.

Centrifugal pump Centrifugal pump

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. Furthermore, the mud mixing pump is also combined with centrifugal pump and hopper.


Famous brand centrifugal pump

Centrifugal pump has long history for the wide using field. In solids control industry the worldwide famous brand is Derrick, Mi-Swaco, Misson pump come from NOV, etc.

Key issue on centrifugal pump work

Centrifugal pumps for Desanders, Desilters, also Decanter centrifuges the drilling mud, especially the dirty drilling fluids with drilling cuttings particles will abrade the pump impeller, liner, etc. The qualified centrifugal pump for solids control industry the key issue is the axel, wet parts are durable and wearable enough.

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

GN manufactures centrifugal pumps mainly used in drilling fluids solids control according to clients’ actual working condition, detailed requirements, also other customized services for special demand.
