PUMP CASING

The casing is axially split, which permits removal of the complete rotor without moving either piping or motor. Pumps generating high heads have double volutes to reduce radial forces, ensuring minimal shaft deflection and low bearing loads. Replaceable wear rings protect the casing at the impeller running clearances.

IMPELLER

The closed impeller have double curved vanes. The double suction design gives practically zero axial forces. Each impeller is dynamically balanced according to ISO 1940-1 standard.

BEARING

On both sides grease lubricated deep groove ball bearings.

SHAFT SEAL

Soft-packed stuffing box. Cooling lines are provided for additional cooling of the graphite impregnated type gland packing.
