Pump Efficiency Testing

Orifice Plate MethodPumps are tested using the Orifice Plate Method.

The flow and vacuum generated during this process is used to plot an actual performance curve.

Comparing this curve to the manufacturers’ published curve gives a measure of the pump’s efficiency.

Are your pumps wasting too much power?

  • An important point to consider when testing pumps is that a poorly performing pump will be absorbing as much, if not more, power than a new pump, while adding little in the way of flow and vacuum.
  • The extra power consumed per annum will often exceed the cost of overhauling the pump at Rezitech’s workshop.

Vacuum Pump TestExample - Nash 904 P2

Flow:  Produces approx 6,400 CFM

Power:  Absorbs approx 216 kW

Operating Cost:  Based on running 24 hours/day, 5 days/week, 46 weeks per year, $0.0434/kWh.

= 216 x 24 x 5 x 46 x 0.0434

= $51,745.00 per year.

 

  • If pump testing at duty point (20”Hg) shows that the efficiency is only 54%, then the pump is wasting 46% of its absorbed power.
  • Payback period based on average repair cost would be just over one year.
