Self-priming, liquid-ring pumps enable hygienic operation
Pump Engineering
The CFS AS/ASH Series of pumps (photo) use a self-priming, liquid-ring hygienic design. They are manufactured in cast 316L stainless steel and are electropolished as standard, so they have no “dead spots” that could result in product contamination. This makes them ideal for clean-in-place applications in pharmaceutical, food, dairy and brewery applications, says the manufacturer. They are available in single- and two-stage options with IEC motors fitted as standard. The range includes seven models, which are capable of handling flowrates ranging from 2 to 55 m 3 /h (2,000–55,000 L/h), at heads to 60 m (6 bars). They can also be used in applications where liquids have entrained air or gas. A range of end connections, and ATEX-approved versions are available for enhanced safety. — Pump Engineering Ltd., West Sussex, U.K.
