PROGRESSIVE CAVITY PUMPS

The basis of any Progressive Cavity Single Screw Pump is a power section which usually consists of a metal rotor (n-start external helix) and a rubber stator (n+1-start internal helix). Rotation of the rotor inside the stator creates sealed cavities that progressively move from suction to discharge side of the pump producing differential pressure.

TASK: Feed the drilling mud to the centrifuge at the rig for cleaning. The customer asked to design a screw pump unit which has the following parameters: working pressure 2 - 4 bar, capacity in the range from 3 to 20 m3/h. 

The main condition of the customer is the use of the motor-variator as part of the SOLTEC ® pump unit for the possibility of manual adjustment of performance.


SOLUTION: Within mentioned task, specialists of SOLTEС ® have selected and manufactured a horizontal single-screw pump BN063L01HYXV with a capacity ranging from 3 to 20 m3 / h and an operating pressure of 0.1 to 6 bar.

The flowing part of the pump unit is made of materials resistant to drilling muds containing abrasive particles.
