3 ways to improve the efficiency of your pump system

Size pumps carefully

Unless sized accurately, a pump will be subjected to unnecessary wear which eventually results in early failure. If your pump makes excessive noise, requires frequent bearing and seal replacement and runs intermittently, it may be oversized for its purpose. Contact your pump supplier to identify the optimum size, making sure to have the flow rate, total head, liquid to be pumped and information on the pump’s power source to hand. We’ve got lots more information on pump sizing here.

Use a variable-speed drive

In processes with variable load demand – such as wastewater applications or food processing – the pump’s speed can be controlled by connecting it to a variable-speed drive (VSD). Compared to traditional flow rate control methods such as throttling, a VSD allows the pump to use only as much power as the application demands. Substantial savings are achievable: for example, a pump running at 50% speed consumes one-eighth of the energy compared to one running at full speed.

Perform regular maintenance

A comprehensive programme of regular maintenance will help maximise the service life of your pump and maintain its energy efficiency. This should include:

  • Bearing inspection, repair and lubrication
  • Impeller checks and replacement
  • Pump/motor alignment checks
  • Inspection and replacement of seals.

As a supplier of a wide range of pumps – including high-performance Lowara pumps – we know a thing or two about helping our customers increase efficiency and reduce energy costs.
