Licher Brewery has reduced the time needed for yeast harvesting by six to seven hours per week after replacing two centrifugal pumps with a Certa Sine pump from MasoSine.

A Certa Compact 300 pump now performs the work previously carried out by two centrifugal pumps, resulting in a quicker production process and lower energy consumption.
The Certa Sine pump is used in the production of Licher and Benediktiner beers brewed at Licher Brewery, near Frankfurt. It transfers yeast from six to 10 fermentation tanks to yeast storage tanks or waste handling systems.
The pump provides strong suction to transfer thick yeast approximately 100 metres, while also protecting yeast viability with gentle handling, low-shear sinusoidal technology. Previously, transferring high-viscosity yeast with two centrifugal pumps took eight to 10 hours. With the Certa pump, the same task takes just two or three hours.
“Since installing the Certa pump, we have been able to make our processes significantly more efficient,” said Sascha Kläs, master brewer at Licher Brewery. ““Since installing the Certa pump, we have been able to make our processes significantly more efficient. The entire yeast-harvesting process can be completed much more quickly and efficiently because the yeast is collected faster. In addition, the consistent pumping conditions make it possible to use automation.”
Lars Lux, sales engineer, food and beverage and clean process for Watson-Marlow in Germany, said: “It’s impressive how big an impact the Certa pump has had on the yeast harvesting process for the Licher Brewery yeast. It used to take one fixed centrifugal pump and one mobile pump at the same time to do the job, but now only one Certa pump does the same job.”
