Some studies have shown that 30 to 50 per cent of the energy consumed by pump systems could be saved through equipment or control system changes. The fact is – monitoring pump efficiency and rate of wear will save you money.

In today’s world where there’s an increased awareness of the need to use energy efficiently and operate in a manner that is sustainable, in the pump industry there is constant pressure on users to reduce energy wastage, reduce costs and reduce pollution.

The saying goes “If you cannot measure it, you cannot manage it”.  This is also true for energy wastage and being able to know where and how much energy is wasted, is the first step to reducing energy wastage. The question that needs answering is: If I want to save money, when is the ideal time to rebuild my pump?

Real-time efficiency monitoring or pump tests?

The Marcor Pump Efficiency Monitor measures real-time pump energy wastage and flow rate accurately, using the thermodynamic method as described in ISO5198. It allows you to manage your pump and pumping system’s performance in real-time rather than relying on periodic pump test results. Any condition that arises which can lead to energy wastage or pump damage, can be responded to immediately.

The Pump Efficiency Monitor was developed to provide pump and asset managers with a reliable tool to accurately measure and monitor energy wastage and to be able to confidently forecast maintenance activities. This efficiency monitor provides all the necessary information to realise significant savings.

For the price of two or three pump tests, pump end users can now monitor the performance of their pump in real-time for at least the next 20 years. Pump management staff can spend more time managing pumps and pump systems to reduce energy wastage, and less time collecting pump performance data in the field.

The device uses the thermodynamic method for determining the energy losses in the pumped fluid.  This method has the advantage of determining percentage energy losses by measuring the changes in pressure and temperature across a pump.  It does not require a flow meter reading.

The key parameters the monitor measures are energy wastage (%), pump efficiency (%), cost of pumping (kWh/kl), flow (l/s), head (m) and power (kW).
