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.

Pump unit BN011S02FYV has been made under the request of one of the largest company that does maintenance of railway locomotives.

This pump is designed for pumping solutions of flocculants.

Pump capacity regulated by a variator in the range of 10 - 100 l / h.

The maximum permissible fluid temperature is 95 ° C.

Operating pressure at the outlet of the pump unit is up to 3 bar.

The internal thread size of pipe connections is ½ ".

All working parts of the pump that come into contact with the pumped liquid are made of stainless steel 321 AISI.

The stator of the pump unit made of abrasion resistant elastomer.

Motor power 0.55 kW with mains supply 380 V.

Reducer and a mechanical variator made by VARMEC (Italy).
