RER Test Loop

Prove Your Pump Performance

Whether you are an original equipment manufacturer, or the end user, our test loop is available for your testing needs. 

Our state of the art test loop meets the demands of your critical rotating equipment. 


With flow capacities to 162,000 GPM, there are very few pump applications we cannot test. Our reservoir holds over 300,000 gallons of water, providing adequate supply of water while retaining laminar flow at the pump's suction. 



All of our pipes, flanges, and instrumentation on both 24" and 42" vertical pump lines are rated to 150 PSI. All of our Rosemount pressure transmitters are annually calibrated. A four pressure tap ring manifold is used to ensure accuracy of discharge pressure readings. 


Our Eaton 480v and 4160v variable speed drives are the work horses of our test loop. The 480v drive can power motors to 700 HP, while our 4160v drive can deliver power approaching 3000 HP.
