1

High operating reliability
Thanks to the double-entry impeller (compensating the axial forces) the load on the generously dimensioned, pre-loaded, maintenance-free bearings is minimal.

3

Service-friendly design
The self-centring upper part of the casing and the springloaded rotor enable cover and rotor assembly without any adjustments. For maintenance, the cover’s hexagon head Bolts are completely removed from the casing. The casing split flange can therefore be easily and thoroughly cleaned, and the inside of the pump is freely accessible.

2

Low maintenance costs
The combination of solid bearing brackets, a short and rigid shaft, and pre-loaded bearings guarantees low vibrations and long operating lives of bearings, Seals and coupling. Corrosion and abrasion resistant materials ensure top service lives for shaft protecting sleeves, impeller/casing wear rings, and impeller. 4

Optimal tightness
The solid casing split flange at the upper and lower casing part ensures reliable and trouble-free sealing of the upper and lower casing halves.
