Data table
Maximum operating pressure
Pump casing
16, 25 or 30 bars depend on the model
Maximum suction pressure
10 bars
Note : real inlet pressure ( pressure at 0 flow delivered by the pump must
be below the maximum operating pressure of the pump. In case of exceeding
maximum operating pressure, the ball bearing and the mechanical seal could be
damaged or lifetime could decrease.
P Inlet + P at 0 flow ≤ Pmax pump
See pump rating plate to know the maximum operating pressure: Pmax
Temperature range
Liquid temperatures
-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)
Ambient tempereature
-15° to +50°C (other temperature on request)
Electrical data
Motor efficiency
Motor according to IEC 60034-30
