Watson-Marlow Pumps has revealed that a Belgian brewery has installed a 520 series close-coupled peristaltic pump to help dose very specific quantities of sugar into premium beer.

When Brasserie de Blaugies won a significant ongoing order to fill 20- and 30-litre plastic fermentation vessels with one of its beers, the challenge was to dose the precise amount of liquid sugar to ensure the beer is brewed to offer the required levels of alcohol and flavour.

For each vessel, a precise measurement of liquid sugar is required.

Too much or too little sugar can be disastrous for the final product.

Following a site visit and initial dialogue, Andres Urban from Watson-Marlow Pumps was able to recommend the 520 series close-coupled peristaltic pump, which features Memodose for accurate single-shot dispensing.

The pump is rated for 24/7 duties, although at Brasserie de Blaugies the pump typically works for one week and is then idle the following week while other operations aside from filling are undertaken.

Installed in September 2009, the 520 series pump accurately doses the sugar quantities into the vessels after the other beer ingredients have been pumped in at a temperature of 2C.

After a certain period of fermentation, the beer is decanted into smaller bottles ready for sale.

Peristaltic technology ensures nothing but the tube touches the fluid, therefore eliminating the risk of the pump contaminating the fluid or the fluid contaminating the pump.

The complete closure of the tube, which is squeezed between a roller and the track, gives the pump is positive displacement action, preventing backflow and eliminating the need for check valves when the pump is not running.

The 520 series pump at Brasserie de Blaugies is used in combination with Marprene tubing, Watson-Marlow’s thermoplastic elastomer.

A second bottling line is planned for next year, which will also feature Watson-Marlow pump technology.
