Design description

 

Horizontal slurry electric pump units are made on the basis of strengthened running poles. The material of pumps setting components is wear-resistant high-chromium cast iron. The impeller is fixed on the shaft with the help of acme thread. The shaft seal consists of stuffing box or stuffing box together with hydrodynamic seal (impeller).

In PGN700/32 and PGN1000/45, PGN2000/50 pumps it is stipulated for supply of locking liquid into the areas of the most intensive abrasive wear of the setting.

In PGN700/32 and PGN1000/45 pumps instead of armored inserts from wear-resistant cast iron it is provided for installation of armored inserts from rubber, reinforced with collars from steel.

Torsion torque is transferred from electric motor through flexible coupling.

The units are installed on the frames of molded or welded construction.
