The screw pump as an ideal mud pump to feed drilling fluids since the fluids may flow along with the shaft with a very slow inner flow speed, which will not change the pump’s capacity, but will keep the pressure steady so that no vertex or agitation will be produced. Besides, the screw pump play an important role in drilling waste management for wet mud and cutting transportation.

Advantages of AIPU Screw Pumps in Mud Cleaning
Why do engineers select AIPU screw pumps?
+ Slow Speed, Simple and Rugged design
Probably 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.
+ No collection sump required = minimum head
A screw pump ‘scoops’ the water directly from the surface and does not require a collection sump. This keeps the pump head to a minimum.
+ Long lifetime
Screw pumps with typical lifetimes of between 20-40 years are common.
+ Pump capacity is self-regulating with incoming level
When incoming water-level goes down, as dry weather flow, the screw pump ‘automatically’ pumps less water. Ergo: no control system required to adapt pump performance.
+ Easy maintenance
A screw pump requires very little maintenance. Besides no ‘highly skilled’ maintenance staff is required which makes this type of pump very suitable for remote locations.
+ Constant high efficiency with variable capacity
The efficiency-curve of a screw pump is flat on the top. Due to that efficiency characteristic, the screw pump offers even high efficiency when it works at 50% of its capacity.
+ Can run without water
A screw pump can operate even when there is no water in the inlet. Therefore it is not necessary to install expensive measures (level control etc) to prevent dry-running. The lower bearing does not need cooling.
