Factory wholesale Offshore Drilling Rig Platform - Screw Pump – MJ

Single Screw pump also called Positive Displacement Pump or Progressing Cavity pump. Screw pump have many special technical advantages over other type pump and screw pump have much wide application range. The screw pump can transfer the liquid continuously without pulse, and with stable discharging pressure. By selecting proper materials for pump stator and rotor, the screw pump can be applied for many industries.

 

International brand screw pump like Netzsch Nemo pump or NOV Brandt Mono pump, they are both single screw pump suitable for drilling mud transportation. MJ Screw pump have similar technical features with NBR stator and stainless steel rotor to get reliable working performance.

 

In oilfields, the screw pump have many functions as follows: Suction the drilling mud and feed to decanter centrifuge / Working as flushing pump to flush the screen basket of vertical cutting dryer / ideal pump to work with dewatering unit / Ideal pump to transfer the drilling mud or oily sludge with higher solids content.

 

Except for screw pump, centrifugal pump is also very popular in oil drilling mud system. Because of the excellent oilfield design, lower production cost and better anti-abrasive performance, the centrifugal pump can be used to transfer the drilling mud from tank compartment to next equipment / compartment.
