The shipping weight applies to single head pumps without an add-
on power end.
The permissible priming pressure on the suction side is approxi‐
mately 50% of the max. permitted back pressure.
With double head pumps, the maximum permissible back pressure
reduces from 7 to 5.5 bar or from 4 to 3 bar.
All figures refer to water at 20 °C.
The suction lift applies to filled suction line and filled liquid end -
when installed correctly.
The priming lift of 2 m applies to clean and moistened valves and a
clear outlet.
Only with "M - modified" design:
Main pumps with 1500 rpm motor at
50 Hz operation
