Pump Testing
Our service uses Yatesmeter technology to allow us to take a snap shot of your pump and establish its efficiency. A comprehensive report is produced which displays the pump performance curves, provides cost savings analysis and makes refurbishment/replacement recommendations to ensure the optimum performance of your pumps.
The Yatesmeter system, developed and perfected at AEMS, employs the thermodynamic method as detailed in ISO 5198 and in the “Code of Practice for Pump Efficiency Testing by the Direct Thermodynamic Method” issued by The Pump Centre, UK.
The method involves insertion of temperature probes and connection of pressure transducers on both the suction and delivery sides of the pump to measure the differential fluid temperature and pressure. The energy lost due to the inefficiency of the pump is measured by the differential head and differential temperature across the pump. Neither the flow rate nor power absorbed by the pump needs to be measured. Where the shaft power absorbed by the pump can be determined, the flow rate may be calculated from the power absorbed, the differential head and the measured efficiency.

The technology works well for pumps with heads as low as 10 m.
The accuracy is several times better than that achieved by using the conventional testing method. Accuracy better than 1% is achieved in most cases. This method works equally well on blowers and hydro turbines.
Yatesmeter Mark V can be used to test pumps in high temperature applications such as Boiler Feed Pumps.
