Test Facilities

Pump Supply & Repair Group is unique in our Industry as a performance test is carried out on every unit that is repaired before it is despatched.

In carrying out a performance test we are able to compare the result of the the repaired unit versus the OEM (Original Equipment Manufacturer) results. We aim to exceed 80% of OEM unit results. We also record a complete set of condition monitoring results to establish a ‘carpet’ reading which can be compared to site results once installed. This gives our clients the piece of mind that when the unit is installed, it will perform correctly first time.

We also provide a Performance Test Facility to many OEMs and pump repair companies who do not have their own facility or it is not large enough for particular jobs.

Why Performance Test? 

  • Proven Performance & Quality – Clients want to run equipment at its’ optimum efficiency. Running Pumps which are worn & inefficient is time consuming and costly with respect to electrical consumption.
  • Test Certificate Issued &  Performance Curve – Test and OEM Curve Compared
  • Condition Monitoring Readings – Proven bearing conditions
