Brewery laps up energy savings

When a brewer approached Grundfos Pumps to undertake an energy check on part of its operation, it was sure that Grundfos could help it to deliver savings, as the company has been at the forefront of energy-optimised pump development for years and is proud of its approach to sustainability.

Finding out what energy savings could be achieved was straightforward, as Grundfos provides diagnostic tools such as an Energy Check and Pump Audit that establish the current pump system performance. These tools also provide various post-analysis reports with details on the potential savings and payback periods, together with various pump options.

In the case of the brewing company, the energy check showed that a potential energy saving of 148,645kWh could be achieved by changing just two pumps. Better still, the payback period was just six months.

The pumps were duly replaced with two Grundfos NB 65-200 – reliable, single-stage, standard bloc pumps, which are manufactured at ISO9001-certified facilities.

The complete range of Grundfos pumps comprises a series of close-coupled (NB family) and long-coupled (NK family) pumps that are compliant with DIN EN733 or ISO2858. All of these are non-self-priming, single-stage, centrifugal pumps with axial suction port, radial discharge port and horizontal shaft.

The pumps have now been installed at the brewing company for some time and are not only delivering in terms of the promised energy efficiency, but are also proving to be reliable, as they continue to deliver optimised pumping operation.

A key customer benefit in this particular 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 that these pumps are contributing towards the brewing company’s global energy reduction targets.

All in all, Grundfos is supplying many good reasons for saying “cheers”.
