Pipework and installation
6.1 Pipework
Clean pipework thoroughly before connecting it to the pump. Suction pipes must have the same
diameter as the pump’s suction port (for larger diameters, seek VARISCO Spa’s advice). Where
possible, avoid curves, elbows or constrictions liable to limit the flow of liquid to the pump.
Install the pump as near to the liquid to be pumped as possible. Where possible, try to reduce the
length of the suction pipe.
Suction pipe connections must be completely airtight: check pipe threads, flange gaskets, quick
couplings etc.
