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.
We are the borehole pump specialists in our Group, and our Group Company ‘Integrated Water Services’ (IWS) also assess production and distribution pump performance. Please contact IWS for a full suite of pump curve and energy diagnostics services, plus ask about their specialist workshops for offsite testing, redesign and pump refurbishments.
