Are your pumps running to maximum efficiency? Energy efficiency is a rising priority for all Top-10-Tipsbusinesses yet understanding the energy consumption of key pieces of equipment; namely pumps, is lesser understood.

Here Andy Cruse, Business  Development Director - Pumps, at ERIKS talks through the top 10 tips to pump efficiency.

1. Understanding power consumption
The old adage you can’t manage what you don’t measure is never  truer than in pump efficiency with up to 87% of the total lifecycle cost of a pump attributed to energy.

2. Establish performance data
During the installation process, record the initial performance data of the pump and then continually monitor and record it at regular intervals.

3. Monitor flow
If a flow meter is not incorporated in the system it is important to carry out periodic flow testing. This is can be done by nonintrusive devices.

4. Identify discharge head
Take a reading when the pump is fitted and keep a record. If this figure changes over time, it may be indicative of a problem.

5. Identify suction head
Many pump problems actually occur in the suction area so it’s important to measure and monitor regularly. Where filtration is used, it is important to install differential pressure monitoring. This will highlight filter blockages.

6. Record maintenance and repair data
Record maintenance and repair data to establish Mean Time Before Failures (MTBF) records as well as running hours at every intervention and ensure that you log entries.

7. Record running amps
Ensure that you closely monitor and record running amps as part of any Condition Based Maintenance (CBM) data collection.

8. Assess all pumping systems for potential energy reduction
Any pump with a varied load or demand has the potential for energy savings. Consider the installation of Variable Speed Drive’s where possible.

9. Never simply replace like for like
Always reassess your requirements when your pump is due for replacement. Many people replace like for like despite the fact that system requirements and needs may have changed or even the wrong equipment was specified originally.

10. It pays to seek advice
Whether you need advice due to system failures or during the specification process, it pays to bring in the experts to help identify the right solution.
