Locally made pump test modules help keep hydraulic power units in optimal condition.

Recently HYDAC provided pump test modules to a world-leading resources company to help keep hydraulic power units in optimal condition.

HYDAC Australia’s Adriaan Engelbrecht, based in Perth, said the in-house designed pump test modules were an added feature on the HPUs supplied by HYDAC to the resources company.

Pump efficiency testing automatic

“The HYDAC modules automatically test pump flow rate, pressure levels and overall pump efficiency, among other things,” he said. “All these functions can be fully remotely monitored by the company’s Plant Information Management System.

“The system automatically tests pump efficiency within a specific time period, by automatically running through a test sequence.”

Trend on pumps informs preventative maintenance

The data, generated by running these tests within timeframes and hard parameters provided by HYDAC, gives a performance trend on the pumps, including information on the pump’s condition and whether it has been deteriorating over time.

“This information then informs the preventative maintenance required on the pumps, which is an effective way of maintaining healthy pumps and reducing downtime,” said Engelbrecht. “If set points are exceeded, immediate warnings are sent to necessary personal.”


HYDAC was contracted to commission two of the resources company’s HPUs in October and November 2021.

“Last year we manually went through the pump test modules to see if they were operating,” said Engelbrecht. “Just before Easter we assisted the customer with on-site commissioning, and I’m happy to say the module ran smoothly, and implementation was easy.”

HPU monitoring a focal point

Engelbrecht highlighted that HPU monitoring has been a focal point in their development.

“In line with this, the company has a CME module on HPUs and pump test monitoring,” he said. “Overall, the added value that this kit brings is a great company investment to keep HPUs in tip-top condition.”

In addition to pump testing and condition monitoring, HYDAC offers an extensive product range to cover all areas of fluid power. The company also provides on-site reliability audit program, cleanliness solutions for oil and fuel, calibration services, engineering advice, bespoke design, drawings, hydraulic services, technical training, and Industry 4.0 solutions.
