Screw pump is one kind of horizontal type pump. It is made of high
quality S.S304. For well drilling solids control centrifuge, we use
screw pump to transfer drilling fluid from desilter tank or mud
We know screw pump can be made of high quality stainless steel 304
to S.S316L. That means the rotor, stator.
Centrifuge feed pump is a positive-displacement pump that use one
or several screws to move fluids or solids material along the screw
axle. There are single screw pump, double screw pump, the triple
screw pump, as well as the quintuple screw pump. For drilling mud
process, we use the screw pump to transfer drilling fluid to Decanter Centrifuge from desilter tank or centrifuge tank
Screw pump transfer drilling fluid via the Screw Conveyor rotation. Center screw pole is the positive pole, the two sides
screw conveyor are negative pole. Negative poles rotate at opposite
direction with positive pole.
Actually when the screw conveyor is rotating, lower V room will
become large. V room will close against fluid sucked. Closed room
will be pushed forward along axle. Then new suction cavity
generates on suction end. One and one closed cavity move forward,
the fluid will be pressed out.
Compared to other pumps, screw conveyor is hard to lead swirl. This
help much to maintain pump capacity. It is not sensitive to
viscosity so it is capable to transfer material with high
