When a well-known name in the brewery industry in the UK approached Grundfos to undertake an Energy Check on a part of their operation, they were sure they could help to deliver real savings. This is because Grundfos have been at the forefront of energy optimised pump development for years and take real pride in their achievements and their approach to sustainability.
Finding out what energy savings could be achieved is straightforward as Grundfos
provide a range of diagnostic tools such as an Energy Check and Pump Audit that will establish the current pump system performance. Not only that, but these tools also provide various post-analysis reports that include details regarding the potential savings and payback periods as well as the various pump options you could opt for.
This is what happened in this particular case, when an energy check was undertaken which showed a potential energy saving of 148,645 kWh could be achieved by changing just 2 pumps. Better still, the payback period was just 6 months.
The pumps were duly replaced with 2 x Grundfos NB 65-200 these reliable single-stage,
standard bloc pumps.
With their enviable reputation the Grundfos NB(E), are manufactured at ISO 9001 certified facilities, and today the range comprises of a complete series of close-coupled (NB family) and long-coupled (NK family) pumps that are compliant with DIN EN733 or ISO2858. All are non-self-priming single stage, centrifugal pumps with axial suction port, radial discharge port and horizontal shaft.
The pumps have now been installed for some time and are delivering not only in terms of the promised energy efficiency, but also are proving to be very reliable as they continue to deliver optimised pumping operation.
A particular key customer benefit in this instance is that the pumps can be automatically slowed down at weekends when production is not as high. This is a great way of saving additional energy and means these pumps are contributing towards their global energy reduction targets.
All in all Grundfos are supplying many good reasons for saying cheers.
