A = Frequency 50 Hz / single-phase / 230 V
B = Frequency 60 Hz / single-phase / 220 V
C = Frequency 60 Hz / single-phase / 230 V
D = Frequency 50 Hz / three-phase / 400 V
E = Frequency 50 Hz / three-phase / 230 – 400 V
F = Frequency 60 Hz / three-phase / 220 – 380 V

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 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.
