Pumps currently consume 10% of global electricity and most are needlessly inefficient. Grundfos Pumps offer a wide range of high efficiency pumps and advanced motor technology that can reduce the average pump’s energy consumption by up to 60%.
Ascertaining the efficiency of your pumping solutions can be complicated which is why Grundfos have devised a range of tools that can be used to help customers achieve the maximum efficiency from their pumping equipment that will save both money and CO2.
To ascertain the sort of savings you could make, Ashworth can arrange for one of the specially trained Grundfos energy team to undertake an energy survey that will assess all of your installed pump equipment and will look at the current and future demands of that system.
The team will then produce a comprehensive report that will document any suggested changes and the potential savings that they offer, along with giving an overview on the payback period.
In order to undertake a more comprehensive assessment of your pump installation there are certain instances where Ashworth will suggest that it would be beneficial to undertake a thorough pump audit. Grundfos has developed a pump audit tool that will tell you how much money you could save by optimising your pump system, as in many pump systems more than half of the energy consumed by the pumps could be saved by switching to more efficient and correctly sized models.
The Grundfos Pump Audit is a detailed check-up of your pumps system. It checks the overall efficiency of your current pumps and highlights how much energy you could save by switching to a more efficient pump. But don’t just take our word for it, see an example of how Unilever benefitted from a pump audit below:
Unilever wanted to investigate several critical areas where the factory had the opportunity to reduce the power consumption of its existing pumps.
The pumps being used were 20 years old and were fitted with 37kW motors, running constantly with limited control of the motor. To control the flow, the discharge valve had been shut by almost 40%. It was agreed that in this instance the Grundfos Pump Audit tool should be used to undertake the assessment and was duly fitted to the sites 8” pipework in order to understand the process requirements downstream.
The subsequent report from the audit concluded that the existing 37kW pumps were costing more than £16k per annum to operate, once the correct duty had been calculated it was agreed that the replacement pumps would now only need to be rated at 15kW. This meant that a fixed speed replacement pump would have reduced costs to less than £7k per annum.
To further increase savings by 20%, Unilever opted to install Grundfos variable-speed pumps. The variable-speed solution has given Unilever greater control over the process, and the new pumps need only operate at a running speed of 45 Hz to supply the process. The payback period for the new pumps was a mere 12 months.
Should you decide to go ahead and wish to replace the pumps with the recommended Grundfos suggested updated equivalents, Ashworth and Grundfos will be pleased to offer you a way to reduce the cost of these new pumps by arranging for the recycling of your existing pumps and giving you an agreed value that will be used to offset against the price of the new pumping equipment.
