The Stallion series are developed for pumping fluids with high solid content. A shock-absorbing polyurethane screen base absorbs the impact from constant assault by solid particles. 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. These pumps are made for rugged utilitarian applications that require a robust design.
Stallion pumps now also come equipped with the Wilden Pro-Flo Shift ADS.
The Pro-Flo Shift incorporates an 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, 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).
