3.2 Data table
Maximum utilisation pressure
Maximum operating pressure See pump type key on rating plate and paragraph 3.1
Maximum suction pressure 6bar
Notice: the suction pressure (Pinput) + the pressure at
zero delivery rate (Pzero delivery rate) must always be
lower than the maximum permitted operating pressure
(Pmax). Pinput +Pzero delivery rate≤ Pmax. Refer to
the pump rating plate for the maximum operating pres-
sure: Pmax.
Temperature range
Fluid temperature -20°C to +120°C with EPDM seals
-20°C to +90°C with VITON seals
Ambient temperature -15°C to +50°C
