The most business of DC Machinery is the overseas. Meanwhile, DC Machinery solid control system can also used in HDD, CBM, and water well drilling. If you have dirt mud can’t process, please contact us, you will get the cost solutions.

SB Series Centrifugal pump is used for transferring slurry or mud or water. It can be used as feeding pump for desander, desilter, or used as mixing pump for Jet Mud Mixer. Also it can be used as trip pump, and supercharging pump for rig mud pump.


Recent days, DC solid control got a repeat order from Pakistan for 12 sets SB series centrifugal pumps used for their drilling site. All model centrifugal pump use tungsten carbide mechanical seal, with famous brand Bearing. And spare parts interchangeable with most of the international Brand pump which helps customer to source spare parts easily. Open impeller design that lowers axial thrust loads, and make it easier for installation, repair and maintenance.

DC Centrifugal pump has been exported to many overseas countries. The reliable quality and cost effective solutions has helped GN Solids Control to win many orders of centrifugal pump from the world. With our branches and partners around the world, clients can get GN centrifugal pump and parts from local warehouses to save delivery

Centrifugal pump is the ideal equipment to provide impetus for Desander 、Desilter and Jet Mud Mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head. Centrifugal pump is also called sand pump.

DC Solid control shipped 6 sets centrifugal pump to a pakistan users. As we know, drilling mud centrifugal pump is processing drilling fluid with various solid particle and chemical. It is mainly suspending liquid then the pump impeller and casing should be more durable and high anticorrosive capability.

Furthermore, we should consider drilling fluid centrifugal pump should have proper pressure and match well with hydrocyclone separator(desander cone,desilter cone, mud mixing system).

Actually, centrifugal pump work is related with many issues. It can be widely used in many ways with different fucntion also various industries. If you have interest with it, please contact us.


Submersible slurry pump is used in drilling fluid solids control system to pump the thick liquid, thick oil, oil residue, dirty fluid, mud and fluid which contains clay sand slag and corrosive fluid.

Structure of slurry pump

YZ series pump is single stage, single suction cantilever type, using shaft foundation, fulcrum bearing, union pipe
connect the waterpower parts of pump, the liquid is discharged from outlet pipe part, the impeller of pump is semi-
open impeller.


Matters need attention of choose slurry pump 

If we want the best application effect of slurry, we must choose the right slurry model to meet the requirements of relatively medium, disposing effect. We need the data when purchase slurry.

Besides above need notice, slurry pump work 2000hours should be checked, the wearing between impeller and pump body can’t be oversize, the biggest interval can’t extend 1.2 mm.

Screw Pump is an ideal pump used to feed drilling fluids to decanter centrifuge since drilling fluids is pushed to proceed along axial direction evenly. This pump has a strong adaptability to medium,smooth flow,small pressure fluctuation and high suction capacity.With unique design of rotor and stator, low rate of pump internal flow and more stable pressure.

The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of the special geometry shape of the two parts, they form pressurize capacity separately. The fluids flow along with the shaft, inner flow speed is slow, capacity remains, pressure is steady, so it will not generate vortex and agitating. The shaft of the screw pump is made from Stainless steel.

The main advantages of pump are compact structure, small volume and easy maintenance. Rotor and stator, as the wearing parts of this pump, are convenient to replace.

At recent years, screw pump have already became the most common used feeding pump for decanter centrifuge, which have already instead of slurry pump gradually. Compared to centrifugal pumps, screw pumps can move drilling mud axially without turbulence. They are also able to pump fluids of higher viscosity without losing flow rate. Also, changes in the pressure difference have little impact on screw pumps compared to centrifugal pumps.

A screw pump is a mechanical device that is designed to displace various substances from one place to another. Screw pump is a feeding pump for decanter centrifuge instead of submersible slurry pump. The main advantages of screw pumps are as follows:

Slow Speed, simple and rugged design

Probably the main and overall advantage of a screw pump is its superb reliability. The simple design, open structure and slow rotation speed makes it a heavy duty pump with minimal wear that operates for years without trouble.


Pumps raw water with heavy solids and floating debris

Because of the open structure and large passage between the flights a screw pump can pump raw sewage without the need for a coarse
screen before the pump. Both floating debris and heavy solids are simply lifted up. This saves considerably on equipment costs for a
coarse screen or maintenance.

Screw pump scheme

No collection sump required = minimum head
A screw pump ‘scoops’ the water directly from the surface and does not need a collection sump. This keeps the pump head to a minimum.

Long lifetime ( > 20-40 years)

Screw pumps with typical lifetimes of between 20-40 years are not unusual.

SB series centrifugal pump is the ideal equipment to provide impetus for Desander 、Desilter and Jet Mud Mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head.

DC solid control offers a complete line of centrifugal sand pumps to suit for all kinds of drilling application. Size ranges from 3×2-13 through 10×8-14 to 14×12-22.

sand pump

DC Machinery centrifugal sand pumps is made of wear resistant materials, and can be used to handle abrasive cements and drilling fluids in drilling, production, well-servicing, and industrial application. The combination of wear resitant fluid end, merchanical seal and heavy duty power end provides the prolonged service life.

Features of DCSB series sand pump
Double seal: Pump seal adopts mechanical seal combined with packing seal of two-stage sealing, improve the reliability of the seal.
Open impeller structure: Pump impeller to the open structure, more suitable for the high density, high viscosity mud fluid medium.
High efficiency:The design of blade curve is more conform to the requirements of the fluid mechanics, improve the efficiency of the pump.
Long service life: Key components adopt wear-resisting material, prolong the service life of the pump.

Choose DCSB series sand pump means good sealing effect, long life, perfect function and high efficiency.

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.


Features of Sand pumps

Different flow pumps with different horsepower
Tungsten carbide mechanical seal
Units equipped with explosion proof starter boxes
Can be powered by 3 phase 230 volt or 460 volt power systems
Approved for offshore use

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.
