Oil Drilling Screw Feed Pump

APG Screw Pump as feed pump to Centrifuge In Oil Drilling Mud System

What are the APG screw pump and The purpose of it?

The purpose of the screw pump is to deliver a lubricating medium, such as oil, bitumen, slurry, drilling mud with the viscosity of 3-760 cSt at a temperature below 350°C.

The APG screw pump’s working pressure range from 0.6Mpa to 2.5Mpa, and its flow rate ranges from 0.6m3/h to123 m3/h.

Screw pumps are mainly suited to fuel delivery, hydraulic engineering, shipping engineering, petrochemical, and other industry fields.

Standard seal: Mechanical seal, packing seal is available.

Direction: CW seems from the motor side.

Dismantle and display the screw pump

Screw pumps consisted of the discharge port, the stator, the rotor, the flexible section, the middle axis, suction room, seal, bearing, driveshaft, 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 high-quality rubber.

Which type of screw pump we can provide

According to different fluids' content and property, we'll provide a 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, the screw pump is not easy to lead swirl. This helps 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 in the opposite direction with a positive pole.

Aipu screw Pump features

• There is no agitation and pulsation when the medium is delivered continuously.

• Less vibrating and lower noise than others.

• High pressure means high efficiency, and yes we can provide.

• Our screw pumps are simple structure and easy assemble.

• Compressed design, stainless steel shell.

• Durable fast and strong.

Actually, when the screw axis is rotating, the lower Vroom will become large. Vroom will close against fluid sucked. The closed room will be pushed forward along the axle. Then a new suction cavity generates on suction end. One and one closed cavity move forward, the fluid will be pressed out.

How to select a 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, a screw pump can be used in other applications, too. For the drilling mud process, the centrifuge feeding pump is a rather typical use of screw pump. Compared to other pumps, screw pumps holding shorter life or operation life considering the wearing parts. But it's a compact and high effect, many users prefer it then
