Maximum utilisation pressure
Maximum operating pressure
Maximum suction pressure
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.
