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.

The SOLTEC ® Novomoskovsk Mechanical Plant completed an order for the production of pumps for oil recycling products. BN038S02FYBST pumps are equipped with a screw feeder mechanical seal with flushing and temperature sensor mounted on the pump stator.

Automatic protection from "dry run" excludes failure of the pump stator at “dry” work, ie without liquid in the working chamber. The pumps are made for the food products in fully stainless base plate (frame).
