Foodpro 2011 update: pump specialist Watson-Marlow Bredel

On display at Foodpro this year, Watson-Marlow Bredel will be showcasing their peristaltic pumps, which have been designed without valves, seals or glands; instead the fluid contacts only the bore of the hose or tube, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump.

Not only are the pumps design for 100% hygiene, they also conform to stringent levels of sanitary certification, such as USDA, 3A, FDA, USP and NSF Class VI standards.

Another important advantage in the design is their ability to handle problematic food and beverage fluids, while fully sustaining the product integrity. The pumping action is low shear allowing the easy handling of shear-sensitive, foaming, sticky, viscous, or particulate fluids.

With no need for manual handling of products, the peristaltic pump draws product through the tube or hose by a number of external rotating shoes or rollers,

In addition, the pumping action ensures that the tube is fully swept and the suction and delivery orientation enables the pump to self drain.

With a long service life and easy maintenance, Watson-Marlow Bredel pumps enable users to clean in-line at full velocity, without the intrusion of moving parts or the bypass required by most other positive displacement pumps.

Within food and beverage processing these pumps can be found metering flavourings, colours or additives, pumping whole grapes and other lumpy products, handling shear sensitive fluids such as yeast in beer manufacture, transfer of fruit preserves, diced vegetables, cheese curd, chocolate or baking doughs, soup, prepared food, honey or lab dispensing, and meat, poultry or fish processing. Flowrates vary from microlitres to 91 m3/hr and pressures up to 16 bar.

The Watson-Marlow Group also owns Masosine, a sine pump range, which is also superbly suited to this industry.
