Screw pump can only installed horizontally. For some special working conditions, the pump need to be installed vertically and slurry pump may be better choice. This pump can be customize on the submersible length and suck from the bottom of the drilling mud or slurry.

4) Centrifugal pump

 Centrifugal pump cannot be used for feeding centrifuge. It will shear and agitate the drilling mud strongly.
