PEM - Pump Efficiency Module

Low energy costs through intelligent control system

Why accelerating and braking at the same time?

Many processes are very dynamic due to the increasing application of control valves on consuming devices or pumps are designed too large.


In many cases, the quantity provided by the supply unit or its pump is then reduced without the pump’s speed being adjusted.


The inevitable consequence is unnecessarily high energy consumption because even if the quantity is reduced, the energy used by centrifugal pumps is only slightly reduced.

If using peripheral impeller pumps, the energy consumption even increases.

In order to reduce costs, gwk has been offering appropriate frequency converters to reduce the speed of its pumps for many years.
Based on this experience gwk has developed a standardised pump efficiency module.
