display or the pressure indication in the display might be
disturbed in the exceptional case of the direct vicinity
(<1 m from the electronic module) of radio transmission
installations, transmitters or similar devices working in
this frequency range. The operation of the pump is not
affected at any time.

16, 25 or 30 bar depending on the model
10 bar
Notice: the actual input pressure (P input) + the pressure at zero delivery
rate (P zero delivery rate) must always be lower than the maximum
authorised operating pressure (Pmax). If the maximum authorised
operating pressure is exceeded, the mechanical seal and the roller
bearing can be damaged or their life span reduced.
P input + P zero delivery rate ≤ Pmax
Refer to the pump plate for the maximum operating pressure: Pmax
-20°C to +120 °C
-30°C to +120° C (if full stainless steel)
-15°C to + 90°C (Viton version for O'ring and mechanical seal)
-15°C to +50 °C On request for other temperature
