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 the one of the largest Nuclear Power Plant have been manufactured and shipped set of pump units BV076L01HYYX that designed for pumping transformer oil from the tanks.

In particular, screw submersible pump BV076L01HYYX intended for filing of T1500 transformer oil from a under earth tank that has volume of 50 m3 and a depth of 3.5 meters. The performance of such pump unit s 50 m3/h at a head up to 50 meters.

The hydraulic pumps are made of structural steel. To be able to install on the tank, pumps has been equipped with support flanges DN 700. The pump units have motors with climatic execution UHL1, explosion protection 1ExdIIBT4, as well as gearboxes Italian firm VARMEC. On the drive shafts of pumps fitted with double mechanical seals with flushing cisterns.
