Notice: Actual inlet pressure (Pinlet) + pressure at pump zero volume flow
must be below the maximum operating pressure of the pump.
Pinlet + P at pump zero-flow rate ≤ Pmax of the pump
The pump's operating pressure can be found on the pump's rating plate.
Pmax
-15 °C to +50 °C
-15 °C to +40 °C (other temperature ranges upon request)
See rating plate
< 90 %, without condensation
< 1000 m (> 1000 m upon request)
≤ 55 dB(A)
