High operating reliability

1 Optimum balancing of axial thrust by double drum

over a wide operating range

2 Closed, non-split bearing housings with high stiffness

and excellent vibration behaviour

3 Cellular surface wear rings with excellent anti-seizure

properties

4 Staggered shaft diameters with individual fastening of

impellers ensure clear introduction of axial thrust into

the shaft

5 Adaptation of pump casing to rotor deflection line

6 Vanes of suction stage impellers specially profiled for

particular applications by means of computer-assisted

electric-discharge machining

Materials

Suction casing Carbon steel

Discharge casing Chromium steel

Stage casing Chromium steel

Impeller/diffuser Chromium steel

Shaft Chromium steel
