If it is possible that pressures in excess to the limits can occur
it is important to take the necessary measures, e.g. a pressure
relief valve or pressure sensor.
For further assistance contact your local KNF specialist.
Never apply positive pressure to the suction side of the pump.
A small positive pressure of less than 0.5 m water column will
cause the pump to block flow in the pumping direction. On the
application of any higher pressures than this, the pump will
allow the fluid to pass through in the pumping direction.
This can be prevented by using a suitable check / pressure
valve* on the outlet side of the pump.
* e.g. Pressure Control Valve FDV30 from KNF Flodos
