The Stallion® pump series is designed to transfer solid-laden slurries safely and effectively. Large internal clearance and flow-through design keep the pump from clogging while Wilden's patented air distribution maintains ON/OFF reliability. Stallion® technology incorporates an altered ball/seat check valve assembly maximizes part life, increases suction lift, and maximizes flow rates. Ultra-Flex" diaphragm technology increases parts life by utilizing sacrificial rubber and a controlled flex pattern. A polyurethane screen base has been added to the inlet of the pump for added durability.
