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 new Stallion^® Original^™ Metal AODD Pump models powered by the energy-efficient Pro-Flo^® SHIFT Air Distribution System (ADS).

Wilden Stallion Series pumps incorporate many unique design features that make the handling and transfer of fluids with high solid content more efficient and effective. Chief among these are a shock-absorbing polyurethane screen base that absorbs the impact from constant assault by solid particles, resulting in maximized durability. The pumps also feature a large internal clearance and flow-through design to keep the pump from clogging; an integrated suction strainer; and an altered ball/seat check valve assembly that maximizes part life. Featuring simple installation and easy serviceability, Stallion Series pumps are ideal for rugged utilitarian applications that require a robust design.

Stallion Series 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 and includes ATEX compliance for use in potentially explosive atmospheres.

The new Stallion Series pumps are available in three sizes: PS4, 38 mm (1-1/2”); PS8, 51 mm (2”) and PS15, 76 mm (3”). All are available in either aluminum or ductile iron materials of construction, are submersible, self-priming, shear-sensitive, offer increased On/Off reliability, can run dry, have superior anti-freezing properties and can handle pressures up to 125 psi. Depending on the model, flow rates range from 307 to 764 lpm (81 to 202 gpm).
