Constructional design

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

* 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.
