PUMP CASING :
This 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 wearrings protect the casing at the impeller running clearances.


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


BEARINGS :
On both sides grease lubricated deep groove ball bearings, sealed for life.


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