According to Belgium based Packo Pumps, the purchase price of a pump is becoming less and less important. Packo arrived at this by calculating the purchase price of a pump from 2 years ago and with an energy price of €0.2/kWh worked out how long it took for the pump to consume its own value in energy.
For pumps running 40 hours a week, this was between 2 to 2.5 years for smaller pumps and less than 1 year for large pumps. With today’s prices and an energy cost of €0.4/kWh (which is still conservatively calculated), a pump often consumes its own cost price on energy within 6 months.
So, based on these figures, the purchase price of a pump becomes less important, but its energetic efficiency all the more. A pump that is 10% cheaper to purchase, but consumes 5% more power, will cost the same after a year as the more expensive pump. For all subsequent years, you pay the difference in purchase price to your energy supplier each year again and again. And remember, a pump with an efficiency of 60% consumes 5% more energy than another with 63% efficiency!
Packo have done a lot of research over the past 15 years to increase the energetic efficiency of their pumps and ever since has been one of the most important areas of attention for all newly developed pumps. Today, the company claim to have a range of hygienic centrifugal pumps with one of, if not the highest, energetic efficiency ratings on the European market. For more visit packopumps.com
