Hygienic, Air-Operated Pumps Reduce Air Consumption

Wilden, part of PSG, a Dover company, introduced the Saniflo Hygienic Series (HS) Original Metal air-operated double-diaphragm (AODD) pump models that utilize the energy-efficient Pro-Flo SHIFT Air Distribution System (ADS). The Saniflo HS pumps comply with regulatory requirements for use in a wide variety of hygienic applications. The clamped design ensures ease of maintenance and convenient clean-in-place and clean-out-of-place capabilities, noted the company in a press release.

The Wilden Pro-Flo SHIFT ADS technology, introduced in June 2013, achieves up to 60% savings in air consumption over other competitive AODD pump technologies, while providing more product yield per standard cubic foot per minute. The ADS offers plug-and-play operation. It is submersible, and can be used in harsh operating environments and potentially explosive atmospheres. Using fewer operating parts, the ADS prevents overfilling to prolong diaphragm life and reduce noise, maintenance, and repair for less downtime and a lower total cost of ownership.

The new Saniflo HS pumps are available in 316 stainless steel and nickel-plated aluminum in 38 mm (1-1/2”), 51 mm (2”) and 76 mm (3”) sizes and feature maximum discharge pressures to 8.6 bar (125 psig), maximum flows to 844 lpm (223 gpm), and maximum solid-handling size to 60.3 mm (2-3/8”).
