Wilden® Releases Advanced™ High Pressure Metal AODD Pump Models with Energy-Efficient Pro-Flo® SHIFT ADS

Grand Terrace, CA – October 15, 2015 – Wilden®, part of PSG®, a Dover company and a worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce the release of two new 1-1/2-inch (38 mm) Advanced™ High Pressure Bolted Metal AODD Pump models that utilize the energy-efficient Pro-Flo® SHIFT Air Distribution System (ADS).

Wilden_HS_Family-ShotUtilizing a bolted configuration to ensure total product containment, the new pumps feature redesigned liquid paths to reduce internal friction to maximize output and efficiency. They are shear sensitive, dry-run capable, externally serviceable, completely submersible and comply with all CE and ATEX requirements.

The new high pressure pumps also come equipped with the innovative Wilden Pro-Flo SHIFT ADS. The Pro-Flo SHIFT 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 air consumption. By optimizing air consumption, the Pro-Flo SHIFT lowers energy and operating costs, achieving up to 60% savings over competitive AODD pump technologies. Its robust design makes the Pro-Flo SHIFT ideal for use in harsh operating environments.

The two new high pressure pump models are the HS400S, which is available in aluminum, and the HS430S, which comes in stainless steel. The HS430S features an exact installation fit for easy replacement of many existing pumps including an exact bolt down footprint and inlet/discharge connections. Both pumps feature a maximum discharge pressure to 17.2 bar (250 psig). Maximum flow rates are 227 lpm (60 gpm) for the HS400S and 242 lpm (64 gpm) for the HS430S. Diaphragms are available in Wil-Flex™.
