CIP with external pump:
If you use another external pump for you CIP-process, the passive Quattroflow Pumps will be rinsed freely.
Please note the given important information below.
Temperature for CIP-medium: max. 90 °C (194 °F)
Pressure: max. 4 bar (58 PSI)
The flow rate should not be higher than 80% of the maximum flow rate which is given for
the used Quattroflow pump (please see given table below).
Please check the chemical resistance of the product wetted materials against the used CIP
mediums.
The fluid path through the pump is only open in flow direction, from inlet to outlet
connection port. It is not possible to rinse the pump in reversed flow direction, because
the check valve will not open.
