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. Replaceable wear rings protect the casing at the impeller running clearances. Flange drilled to ISO, DIN, BS, or ANSI.

The close double suction impeller gives practically zero axial forces. Each impeller is statically and dynamically balanced according to ISO 1940.

Vertical or horizontal, soft packing or mechanical seal, grease or oil lubrication bearing on request.
