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 authorised 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.
