PS8 Features
Wilden® Stallion® Series Air-Operated Double-Diaphragm (AODD) Pumps are ideally suited for rugged mining applications thanks to their unique ability to handle solid-laden mining slurries with ease. Furthering the Stallion Series pump’s ability to handle the toughest mining applications is a robust design featuring a large internal clearance and flow-through path for large-solids passage that prevents the pump from clogging. The Stallion Series is also designed with a polyurethane screen base at its inlet to provide additional durability.
Stallion Series technology incorporates an altered ball/seat check-valve assembly to allow for solids passage. Its polyurethane screen base at the inlet gives added durability.
- Clamped design with handles for lightweight portability
- Large internal clearances due to modified ball, seats, diaphragms and shafts to handle solid-laden slurries
- Polyurethane screen base to act as an initial filter to keep larger solids from damaging the pump
- Powered by Pro-Flo® SHIFT Air Distribution System (ADS)
