Valve Performance Monitoring System (FVPMS)

Acoustic valve diagnostics for early recognition of wear in delivery valves

Permanent condition monitoring of individual check valves is effected by means of acoustic sensors which are fixed to the outside of the valve casing. They are not in contact with the product and easily retrofittable. The sensor is capable of detecting leaks, even if the loss of output is still less than 1.5 %.

By means of the FVPMS (FELUWA Valve Performance Monitoring System) diagnostic system, the operational safety and availability of pumps is significantly increased since wear is precisely localised and detected at an early stage, which allows for specific forward planning of service and repair.

PVD = Power loss caused by valve leakage (due to wear) during the discharge stroke

PVS =  Power loss caused by valve leakage (due to wear) during the suction stroke
