Screw Pump

Screw pump is an ideal equipment used for feeding slurry for decanter centrifuge in solids control system. DCG Series Centrifuge feed pump is a positive displacement pump, also called screw pump. The GNG positive displacement pump is an ideal pump for feeding to decanter centrifuge without shearing or agitating the drilling mud. The main parts are screw shaft (rotor) and screw shaft bushing (stator).

DCG centrifuge feed pump can drive by coupler, or adjust the speed by using variable speed motor, Triangle V-belt, gear box,etc G series positive displacement pump iswith less accessories, compact structure, small volume, easy maintenance, rotor and stator are wear parts of this pump, it is convenient to replace. The stator is madeof elastomeric material, so it has particular advantages than other pump to transfer the fluids With high viscosity and hard suspended particles included.

Screw PumpFeatures of DCG Centrifuge Feed Pump

1. This pump has a strong adaptability to medium,smooth flow,small pressure fluctuation and high suction capacity.

2. With unique design of rotor and stator, low rate of pump internal flow and more stable pressure.

3. Screw and machine body are made of stainless steel material which is corrosion resistant and has a long service life .

4. With few spareparts ,simple maintenance,easy to be replaced and maintained , compact structure and small footprint.
