ATTENTION The curve refers to the following operating conditions:
Fluid: PETROL,
Temperature: 20° C
Suction conditions: The pipe and the pump position relative
to the fluid level is such that a low pressure of 0.3 bar is
generated at the nominal flow rate.
Under different suction conditions higher low pressure
values can be created that reduce the flow rate compared
to the same back pressure values. To obtain the best perfor-
mance, it is very important to reduce loss of suction pressu-
re as much as possible by following these instructions:
