Variable speed motors save pumps running
costs
Variable speed drives and high efficiency motors can reduce energy costs between 30%-50%, said a pumps supplier, which added that energy consumption represents 95% of a pumps life cycle cost.
Thousands of industries pumps are oversized and continue to run flat out 24/7, Energy represents 95% of a pumps life cycle cost, so the opportunity for savings are substantial, said The Pump Company The company told manufacturingtalk that the use of variable speed drives and high efficiency motors can reduce energy costs between 30%-50%

One of the biggest problems when using pumps is dry running, up till now; there have been no solid answers.
The Pump Company said that it is able to assist in achieving these savings without compromising the pumps lifespan or reliability.
* Throttling oversized pumps wastes energy - traditional methods of throttling oversized pumps result in wasted energy and high costs, said The Pump Company, whereas a variable speed drive ensures that no more energy than necessary is used to achieve the required result.
A centrifugal pump running at half speed will only consume one-eighth of the energy of one running at full speed.
Further, by reducing the pump speed to 80% only requires 51% of the power.
Using the Grundfos range of single and multistage industrial pumps with built in variable speed converters coupled to sensors, allows the pump to automatically control its own speed.
The payback time when fitting this type of equipment will surprise even the greatest sceptics, said The Pump Company.
It added that the development of speed controlled pumps is nothing short of a revolution in pump technology.
