Vacuum ring pumps work for 2 Sisters Cavaghan & Gray 25 November 2013

Food manufacturer 2 Sisters Food Group is reporting success in significantly reducing energy consumption since installing two close-coupled Busch Dolphin LX liquid ring vacuum pumps at its Cavaghan & Gray manufacturing facility in Carlisle.

Matt Soden, category buyer for engineering for 2 Sisters Food Group, explains that the pumps are used on its savoury cooking production line, where the induced vacuum speeds up cooking times and enables cooking at lower temperatures.

"To create a quality product we need quality equipment that can cope with a high moisture production environment, while also keeping our energy usage and costs to a minimum," observes Soden.

"Installing the Busch Dolphins means we are able to deliver first class savoury products that are cooked to the best possible standard, while also meeting our energy use reduction requirements."

Mark Sumnall, UK sales director for Busch, explains that Dolphin's liquid ring technology works with just one moving part, the impeller shaft assembly, which is mounted eccentrically relative to the casing. The liquid ring is formed by the service liquid, normally water, rotating concentrically.

Process gas enters via the suction port, travels between the impeller blades and is compressed prior to ejection through the discharge port with a quantity of service liquid.
