Lowara CEA(M) Centrifugal Pumps

This centrifugal pump by Lowara is made from corrosion-resistant stainless steel and equipped with high efficiency PLM motors.

Lowara CEA pumps are suitable for water supply, irrigation, water circulation, industrial washing, thermal waters and reverse osmosis (where de-mineralised water is used).

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, this 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. We also supply the seal as a spare part for retro fitting to existing pumps and also offer a fitting service. See link in 'Related Products' at the bottom of the page.

Lowara CEA pumps are fitted with FPM (Viton) seals as standard. Other options include:
►WRAS approved seals - For potable water
►Hard faced seals - For abrasive liquids
►Pump body and impeller in AISI 316 stainless steel - For chemically aggressive liquids
