Wilden®, part of PSG®, a Dover company and a worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce the availability of its PS220/230 FIT 25 mm (1”) metal AODD pumps equipped with the energy-efficient Pro-Flo® SHIFT Air Distribution System (ADS). Available in three wetted-path materials of construction – aluminum, stainless steel and ductile iron – the new PS220/230 FIT pumps feature bolted product containment, easier maintenance and efficient operations.
Providing increased performance with no repiping necessary, Wilden FIT pumps have been designed to be direct replacements for existing Wilden clamped pumps, bolted pumps and competitive models. For simplicity of installation, direct replacement means that FIT pumps fit bolt-to-bolt and pipe-to-pipe in existing fluid-handling piping systems. This makes the Wilden FIT pump an easy, cost-effective way to enhance and upgrade existing pump performance with superior bolted product containment.
PS220/230 FIT pumps are shear sensitive and intrinsically safe with self-priming and dry-run capabilities, and offer the longest mean time between repair (MTBR), superior anti-freezing and increased on/off reliability. These pumps also feature the innovative Wilden Pro-Flo SHIFT ADS, which incorporates a unique Air Control Spool that automatically restricts the amount of air going into the pump during the latter part of each stroke, which eliminates over-filling of the air chamber and results in reduced energy consumption. By optimizing air consumption, the Pro-Flo SHIFT lowers energy and operating costs.
Wilden PS220/230 FIT pumps are available with maximum discharge pressures to 8.6 bar (125 psig), maximum flow rates to 254 lpm (56 gpm) and maximum suction lifts to 6.9 m (22.7’) dry, 9.0 m (29.5’) wet. Diaphragms are available in Buna-N, EPDM, Polyurethane, PTFE, Saniflex™, Viton® and Wil-Flex™.
