A compact, double-head hose pump that provides higher flows yet requires less space, is the latest addition to the range of Ponndorf peristaltic pumps. Available from this firm, the PK 40 high-pressure twin unit (photo, p. 32I-7) is capable of providing flowrates of up to 15,000 L/h at pressures up to 15 bar. These self-priming pumps offer advantages of peristaltic pumping that are especially relevant to the food processing and water treatment industries. For example, shear sensitive, delicate liquids, or those containing solids remain unaffected by the pumping process. The pump is fully reversible and is supplied with a wide selection of hose materials, including natural rubber, neoprene, hypalon, food-grade NBR and EPDM. — Pump Engineering Ltd., Littlehampton, U.K.
