Pump Efficiency Testing
G Stow have a brand new pump performance test facility at Wallingford suitable for testing pumps up to 220 KW
Pumps can be installed in the purpose built test tank, which comprises of a 20m borehole, flow is pumped through various pipework & flow meters then returned to the borehole via baffles within the tank.
Flow, head and power is recorded from the test control panel, which will provide information for a performance curve of the pump being tested to be produced.
The test curve will prove the full operating performance of each pump and provide the efficiency of the unit.
