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 of the leader in the field of mining machinery were produced horizontal single-screw pumps BN045S02FY and BN053S02FY for conveying emulsion explosives.

Pump units are designed to pump emulsions with viscosity from 10 000 to 25 000 cPs, at pressure up to 6 bar, with a capacity 7 m3 per hour for BN045S02FY and 9 m3 per hour for BN053S02FY. The operating temperature of the pumped emulsion is from +40 ° C to +80 ° C.

All working parts contacting with the fluid made of stainless steel 12X18H10T. Stators of pumps are made of elastomer NBR.
