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.

SOLTEC ® Single Screw Eccentric Progressing Cavity Pump with hopper and heating system of flow part

Specialists of SOLTEC ® company Novomoskovsk Mechanical Plant specially for mineral resource industry have designed the pumps capable to pump liquid explosive emulsion. The difficult aspect is that the pumping fluid crystallizes when the temperature lowers. To avoid it the pump is equipped by the heat sleeve of chamber and the one of pump working pair. The pump is equipped by the throat for hopper, additional screw feeder and automatics for protection from ‘dry run’.
