Welcome to Variable Efficiency
With over 10 Years experience in optimising pumping systems for the water and waste water industry, we care about reducing the cost of ownership of pumping systems.

OptimiseEveryone knows that variable speed drives are more energy efficient than valve throttling or bypass valves, but by how much can you save? Everyone should get to know their pumping system, it can be very rewarding.
EvidenceWhen preparing the business case for an upgrade we can help with the whole-of-life-cost calculation of various options and compare to existing operational expense.
|
AlternativeTraditional techniques for pump selection leave potential energy savings locked in the past. We can compare selections already made and present a comparison, or provide an alternative selection and compare with existing or proposed.
NetworkWe can compare different network configurations and quantify the differences. Decreasing dynamic system losses can be as energy efficient as decreasing the pump speed.

Using improved methods or tools to assess the efficiency of existing pumping operations... we achieve 20-30 per cent energy efficiency savings

Specific Energy - Identifying how to minimise energy consumption
Above is an example of why it is important to get to know your pumps. Variable Efficiency can advise how to get the most of your existing system, or give advice on future upgrades. See the multi-pump control example on the Services page for further details.
