Vacuum Pump Performance Testing

Avoid costly breakdowns and manage your maintenance program through our Pump Performance Testing Service.

Rezitech’s expert technical team will conduct on site performance testing and analysis to ensure your Liquid Ring Vacuum Pumps are running at maximum efficiency.

With over 30 years experience in service and repair of all makes of liquid ring vacuum pumps, Rezitech Services is an industry leader in this field.

Our fully equipped workshops in Melbourne and Townsville have a large range of parts available. Our vacuum pump services include on-site performance testing, repairs, replacement parts, rental and service/exchange pumps, and sales of new liquid ring vacuum pumps.

Pump Performance Testing

Pumps 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?

  • 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.

Example – Nash 904 P2

Rezitech pump testing graph

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, $0.10/kWh.

= 216 x 24 x 5 x 46 x 0.10
= $119,232.00 per year.

  • If pump testing at duty point (-70kPa_g) shows that the efficiency is only 47%, then the pump is wasting 53% of its absorbed power.
  • Payback period based on average repair cost would be just over one year.

By identifying inefficiencies within both the pump and the wider vacuum system, Rezitech helps businesses lower operating costs, improve production reliability, and maximise system performance.

Regular liquid ring vacuum pump performance testing from Rezitech helps businesses maintain efficient, reliable, and cost-effective industrial vacuum systems. Over time, vacuum pumps can lose efficiency due to wear, contamination, leaks, or changing production demands, leading to increased energy usage and unexpected failures.

Rezitech helps businesses:

  • Improve liquid ring vacuum pump efficiency
  • Reduce electricity and operating costs
  • Minimise unplanned downtime
  • Extend equipment lifespan
  • Identify system faults before failures occur
  • Improve process consistency and reliability
  • Support predictive and preventive maintenance programs

With extensive experience in industrial rotating equipment and reliability engineering, Rezitech provides tailored vacuum system solutions that help clients improve operational efficiency and plant performance.

Rezitech provides a comprehensive liquid ring vacuum pump optimisation service designed to improve system efficiency, reliability, and operational performance. Our technicians assess the entire vacuum system to identify energy losses, pressure instability, leaks, and equipment wear that may be impacting productivity.
Our vacuum pump optimisation services can include:
• Vacuum flow and pressure testing
• Power consumption analysis
• System auditing
• Pump capacity and sizing assessments
• Variable speed drive (VSD) adaptation
• Maintenance and reliability recommendations for liquid ring pumps
Rezitech focuses on delivering practical efficiency improvements that reduce downtime, lower energy costs, and improve long-term equipment performance.
