Wilden®, part of PSG®, a Dover company, announces the release of Stallion® Original Metal AODD Pump models. The pumps incorporate features designed to make the handling and transfer of fluids with high solids content more efficient and effective. A shock-absorbing polyurethane screen base absorbs the impact from constant assault by solid particles. The pumps feature a large internal clearance and flow-through design to prevent clogging; an integrated suction strainer; and an altered ball/seat check valve assembly to maximize part life.
