Wilden®, the worldwide leader in air-operated double-diaphragm (AODD) pump technology, has announced that it has designed its Stallion® Series of Metal Air-Operated Double Diaphragm (AODD) Pumps with the transfer of solid-laden slurries in mind.

Wilden’s Stallion technology incorporates many revolutionary design concepts that make the handling and transfer of fluids with a 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 pump’s also feature an integrated suction strainer, with the option of plumbed suction, if needed.

Stallion pumps also offer Wilden’s patented Pro-Flo X™ air distribution system (ADS) with the Efficiency Management System (EMS™). The EMS allows the user to control flow rates and air consumption with the simple turn of a dial. To better illustrate the many energy- and cost-saving benefits of its Pro-Flo X™ ADS, Wilden has created the See More Green program, details of which can be found at

Wilden’s Stallion pumps are available in three sizes: PX4, 38mm (1-1/2"); PX8, 51mm (2") and PX15, 76mm (3"). All are available in either aluminum or ductile iron materials of construction, are submersible, intrinsically safe, lube-free, can run dry, have superior anti-freezing properties and can handle pressures to 125 psi. Depending on the model, flow rates range from 305 to 776 lpm (81 to 205 gpm).
