2.2

General

For a good operation, the correct installation of the pump is fundamental:
 Before carrying out hydraulic connections, make sure that the inside of pipes, tanks, etc. have been thoroughly
cleaned/washed. However we recommend the installation of a temporary filter near to suction nozzle in order to
stop plant residues and slags.
 Connect pipes avoiding nozzles stretching
 Install pipes correctly sized for the maximum flow rate of the pump, avoid necks and tortuosity where air or gas
could be entrapped.
 Check valves and cross fittings should be installed both in the suction and discharge lines, this will permit to
disassemble the pump without draining the plant and/or to install accessories such as pressure gauges, damp-
ners a.s.o.
WARNING
To prevent serious damages suction and discharge lines must be properly designed, sized
and connected to the pump.
