Constructional design

Housing, impeller, impeller magnet coating and rear casing can be made of either glass-fibre reinforced PP plastic or PVDF. Sleeve bearings, starting ring and centering shaft are made of 99.7% pure oxide ceramic. O-ring sealing of the housing is made of FPM, EPDM or FEP (optionally available).

The pump is equipped with a non-ventilated motor with two shaft ends. A pump head of size 8/60-30 is mounted to each side of the motor. The pump heads may also be connected in series to increase discharge pressure.

* To deliver liquids with a higher relative density, we also offer all our pumps with smaller impeller diameters which, however, reduce delivery rates and heads of the pumps. If in doubt, please consult us.

** Maximum system pressure depends on the temperature of the fluid delivered.
