Brewery Pumps

Whisper Pumps stock a growing range of pumps suitable for breweries.

Over the past few years, we have seen a trend to use Ebara CDX and 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 hot wort transfer 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 Ebara CDX pumps and Lowara CEA pumps with the special seal fitted. We also supply the seal as a spare part for retro fitting to existing pumps and also offer a fitting service.

Lowara CO pumps have these seals fitted as standard and can pump hot wort containing grain, without blocking.
