Efficiency and optimisation
Get more from the system you already have: lower running cost, steadier pressure and fewer breakdowns.
Pumps use more energy than most people expect
Many pumps run flat out whatever the demand, and throttle the excess with a valve. That wastes energy and shortens the life of the pump. Matching speed and size to the real demand often costs less than the energy it saves.
The slider shows the textbook relationship: slow a pump a little and power falls a lot.
- Flow follows speed
- Head follows speed squared
- Power follows speed cubed
Textbook affinity laws for a centrifugal pump: flow changes with speed, head with the square of speed and power with the cube. Real systems differ with static head and pump curve, which is why we assess before we recommend.
Six ways to improve a pumping system
Pump system assessments
Measure how the system really performs today.
Energy-efficiency improvements
Cut power use without cutting service.
Motor and drive upgrades
Replace oversized or ageing motors and add variable speed drives where they pay.
Pressure and flow optimisation
Set pressure to what is needed, not higher.
Condition monitoring
Where it makes sense, watch vibration, temperature and current for early warning.
Water-use efficiency
Find leaks and waste that the pump is being asked to cover.
Controls, pipework and power
Valves and manifolds
Solar power
WaterYour pumping could probably be more efficient if
- A throttling valve is partly closed to control flow
- Pumps start and stop many times an hour
- Pressure is higher than anyone needs
- Electricity bills for pumping keep rising
- The motor is old and much larger than the duty
- Pumps are noisy, hot or vibrating
Frequently asked questions
How much will I save?
It depends on the system. We do not promise a figure before measuring. An assessment tells you where the savings are and whether they justify the cost.
Is a variable speed drive always worth it?
No. It pays where demand varies and the pump is working against a throttled valve or a high static head. It matters less where demand is constant.
Can you monitor pumps remotely?
Condition monitoring is available where it makes sense for the equipment and the site. We will tell you if it is not worth it.
