Back pressure (bar)
The curve refers to the following operating condi-
tions:
Fluid: DEF
Temperature: 20° C (68 °F)
Suction conditions: The pipe and the pump position
relative to the fluid level is such that a low pressure of
0.3 bar (4 psi) 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 performance, 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 Installation).
By-pass pressure is 1.7 bar (24 psi)
The wetted materials used in this device are :
stainless steel, plastic and rubber suitable for AdBlue.
