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 re-
duce the flow rate compared to the same back pressure values. To obtain the best per-
formance, it is very important to reduce loss of suction pressure as much as possible by
following these instructions:
• shorten the suction pipe as much as possible
• avoid useless elbows or throttling in the pipes
• keep the suction filter clean
• use a pipe with a diameter equal to, or greater than, indicated (see In-
stallation).
