Use pipework widths to match the pump's suction and pres‐
sure nozzles.
Weight of the lines
The weight of the lines may not exert a load on the
pump housing.
2.
Lead the suction and discharge lines without tension to the
pump housing.
It is the duty of the operator of the pump to ensure that the connec‐
tions to the suction and pressure nozzles are properly established.
Use pipe or hose material as the suction line, which cannot
n
deform from the negative pressure that occurs, not even at
high temperatures.
You have to keep the suction line as short as possible and fit it
n
so that no gases can accumulate. Always route the suction line
falling towards the pump.
