Non-Intrusive Testing and Plant Inspections

Many installed pump systems are running significantly below best performance, Pump Supply & Repair Group has the equipment, software and expertise to test and optimise any system.

Benefits to the Customer:

  • Optimise Performance
  • Minimise Energy Consumption
  • Increases Mean Time Between Failure
  • Improves Reliability

We are able to do this by following a number of steps:

  1. Review of current installation
  2. Test of current installation
  3. Technical Analysis
  4. Engineers Recommendations’
  5. Implementation of Improvements
  6. Monitoring of Improved system

Before a test takes place, where appropriate our engineer will use one of our Laser Alignment kits, which allows the engineer to adjust the positions of the pump and motor, aided by the ‘live’ display on the equipment which continually updates to show the real-time alignment. Once the shafts are lined up in both the horizontal and vertical planes, a performance test can be carried out.

For large diameter Vacuum systems, our testing procedure involves fitting orifice test flanges, with precision cut ‘test holes’.  A Digital Pressure Indicated (DPI) is attached to the centre of the  plate to record the pressure during the blanking off of each hole during the test. The Performance of the pump is determined by the application of mathematical formulae using the results obtained. A graph is then produced comparing the Test Performance with the OEM Catalogue Curve. The Current absorbed (Amps)  is recorded throughout the test to allow the engineer to calculate the power usage.

Periodically during the test, the engineer will use specialist equipment to measure the vibration at points on and around the unit, and bearing temperatures will be recorded. By inputting this info into Vibration Analysis software, this allows the engineer to assess the bearing condition of the units and assists with arriving at an accurate conclusion as to the overall condition of the unit.

After performance testing, the units then undergo endoscopic inspection, allowing our engineer to visually inspect the condition of the internal components of the pump without having to disassemble the unit.

(Example of endoscopic inspection goes here (screenshot from vacuum report in site??))

Test Reports submitted to customers vary in detail and complexity depending on each customer’s individual requirements, but would normally include;

  • Test Data
  • Performance Curves
  • Comparison of Test Curves with New Design Specification
  • Recording System Performance Data Over Long Periods
  • System Evaluation and Optimisation Recommendations
  • Post Optimisation Review of Pump Network

What types of systems can we do this for :

  • Water
  • Chemicals
  • Processes
  • Vacuum Systems
  • Water Booster
  • Effluent Treatment
  • Boiler Feed
  • Heating/Cooling Circuits
