Design description

 Slurry electrical pump units of PVN type are vertical and made on the basis of unified strengthened running pole. The pumps have longitudinal feed and tangential discharge of operating fluid.

Shaft bearings (frictionless bearings) are installed into thick-walled barrels, which allow mounting the bearings of heavier class. Torsion torque is transferred from electric motor through flexible coupling. The units are installed on reservoir poles with pumping medium.

Bearings lubrication is consistent.

 

Seal

 The shaft seal is of groove type.
