Oil Drilling Mud System Decanter Centrifuge Single Screw Pump

APG Screw pump for decanter centrifuge in oil drilling mud system

APG Screw pumps are for decanter centrifuge feeding. Compared to submersible slurry pump, such pump is higher price and it's horizontally installed instead of vertical position. It's a positive-displacement pump consisting one or more screws to move fluid or solids along the axis. For drilling mud process system, screw pump is usually the single screw rod. 

Screw pumps mainly cosisted of discharge port, the stator, the rotor, the flexible section, middle axis, suction room, seal, bearing, drive shaft, bearing body. Among these parts, the wearing parts are the rotor and stator. The screw pump wet parts can be made of Stainless, steel, and the high quality rubber. According to different fluids content and property, we'll provide the certain configuration on screw pumps. For example, the abrasive material we kindly suggest use the special rubber instead of stainless steel. As we know, the S.S can't adapt abrasive material but corrosive material.Compared to other pumps, screw pump is not easy 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 viscosity

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 axis 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.

How to select screw pump? Yes. It's depending on the centrifuge flow rate request. The screw pump APG series holding capacity from 8m³/h-350m³/h. Besides the solids control system, screw pump can be used in other application, too. For drilling mud process, the centrifuge feeding pump is rather typical use of screw pump. Compared to other pumps, screw pump holding shorter life or operation life considering the wearing parts. But it's compact and high effect, many users prefer it then
