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.

Under request one of the major oil producing company, been manufactured and delivered pump units BN063L01HYXV that intended for supplying of drilling fluid with varying density and viscosity. The capacity control is carried out manually with using of friction variator and can vary from 0 to 25 m3 / h at a pressure up to 6 bar.

For convenience of installation and transportation, the pumps are arranged on the frame structures, that also have the place for the installation of explosion-proof control boxes. The flow parts of pumps made of general industrial steel. The pump units are equipped with electric motors that have explosion-proof level 1ExdIIBT4, and also have gearboxes and variators made by Italian company VARMEC.
