This Pump is highly suitable for breweries
Over the past few years, Whisper Pumps has seen a trend to use Lowara CEA pumps for hot wort transfer in the brewing industry. This is because of the stainless steel construction and the ability to withstand liquid temperatures of up to 110°C. However, we found that customers were experiencing problems with the pumps leaking. This is not a problem encountered when pumping water so we set about finding out why this was happening. We discovered that sugars from the wort were crystallising on the faces of the mechanical shaft seal and forcing the two components apart, thus causing the seal to leak.
After some experimentation, we found a mechanical seal with a material which will still withstand the high temperature but does not allow the sugar to adhere to the mating surfaces.
We now supply the Lowara CEA pumps with the special seal fitted (click here). We also supply the seal as a spare part for retro fitting to existing pumps (click here) and also offer a fitting service.
