The HSD pump is a submersible single-phase portable slurry pump. It is equipped with a high-chromium cast iron agitator that assists smooth suction of the settled matters. Though the pump is a single-phase unit, it has the durability equivalent to three-phase slurry pumps, since the wear parts are made of abrasion-resistant materials.

Automatic model with pendant float set is available.
