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.

For one of the leaders of the Eurasian market in the development and application of new technologies in the field of blasting work have been produced and delivered pump units BN021S02FY and BN076S02FY which designed for pumping of liquid emulsion explosives.

In particular, BN076S02FY pump is intended for conveying of emulsion explosives with viscosity from 10 000 to 30 000 cps, with capacity of 12 m3 / hour and pressure up to 12 bar.

BN021S02FY pump pump is intended for conveying of ethylene glycol solutions during of the emulsion preparation.

The flow part of pumps is made of stainless steel 12X18H10T.

Mentioned pumps should be installed on the mixture and charging trucks, and  designed for using of hydraulic actuators for rotation of the shaft drive.
