Wilden® Stallion® Series Clamped Metal AODD Pumps-- Handle Solid-Laden Slurries with Ease

The Wilden® Original™ Series Stallion® model of clamped metal Air-Operated Double-Diaphragm (AODD) Pumps transfers solid-laden slurries safely and effectively. Large internal clearance and flow-through design result in large-solids passage capacity and prevent the pump from clogging.

Stallion technology incorporates an altered ball/seat check-valve assembly to allow for solids passage. Its polyurethane screen base at the inlet gives added durability. Ready for the toughest utilitarian applications, such as mining, that require a robust design, the Stallion series provides simple installation and easy serviceability.
