Batescrew operates one of Australia's very few privately-owned high-capacity pump test facilities. Tests certified to AS2417 are performed on pumps of up to 1.22 metre (48 inch) bore, at flow rates of up to 3,000 litre/second, using available power of 350 kW.
Three independent test flumes — 150 mm, 450 mm and 1,200 mm diameter — allow the right instrument range to be selected for each duty. Each flume is fitted with a magnetic flowmeter and a 3-phase unbalanced-phase power meter; variable-speed drives to 250 kW give us the resolution to plot a full performance curve in a working day.
All gauges and meters are calibrated to N.A.T.A. standards. A signed performance certificate is issued with every tested pump and is filed against the pump's serial number in the Tocumwal archive.
Inside · the flume
Outside · sump return
Bore · micrometersA closed-loop arrangement is set up around the duty point: the pump under test draws from the sump, passes through magnetic flowmetering, a calibrated control valve and a return leg back to sump. Pressure gauges either side of the pump give differential head; the 3-phase power meter gives shaft input. From those four signals we plot the certified performance curve.
Valves are tested to 1,800 mm diameter, for both static pressure and vacuum flow rates. Sealing tests use the same calibrated rig used for pump certification, so the leakage measurement chain is consistent across both product families.
For projects requiring witnessed testing, our facility can host the customer's representative or third-party inspector. Test reports are issued under signature and stored against the valve serial number for the life of the product.
Every Batescrew pump can leave the factory with a signed performance certificate. Specify it.
