Pump Filters

Overview

Pump filters are typically assembled to the base of Pyrotek molten metal pumps for the purpose of preventing refractory spalls, inclusions and other debris from entering the impeller of the pump. This also prevents these same materials from being transferred. A pump filter provides first-stage filtration in central or remelt furnaces as well as transferring filtered metal between furnaces. The filter life is dependent on the volume of metal pumped and overall metal cleanliness.
