PUMPS FOR FLUIDS MANAGEMENT

Wilden, part of PSG, a Dover company and a supplier of air-operated double-diaphragm (AODD) pump technology, has released its new Stallion Original Metal AODD Pump models. These are powered by the energy-efficient Pro-Flo Shift Air Distribution System (ADS).

The pumps incorporate design features that make the handling and transfer of fluids with high solid content more efficient and effective, including a shock-absorbing polyurethane screen base that absorbs the impact from constant assault by solid particles, resulting in maximized durability. They 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, increases suction and maximizes flow rates.

Featuring simple installation and easy serviceability, Stallion Series pumps are recommended for rugged utilitarian applications that require a robust design. They are also  equipped with 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 a claimed 60 percent savings over competitive AODD pump technologies. Its robust design makes these pumps 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 in.); PS8, 51 mm (2 in.) and PS15, 76 mm (3 in.). All are available in either aluminum or ductile iron materials of construction, are submersible, intrinsically safe, 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).
