Manufactured from high-strength, corrosion-resistant stainless steel, this shaft is longer and more robust than those found in smaller units to accommodate the increased height and weight of the larger tube sheet assembly. Its primary mechanical function is to facilitate the \"bumping\" action, allowing the operator to shift the internal tubes vertically to dislodge spent D.E. powder and trapped debris from the filter fingers. The shaft features precision-machined threading and a dedicated roll pin hole to ensure a secure, slip-free connection with the handle and the internal mounting hardware. Engineered to maintain a watertight seal where it passes through the filter head, it is designed to withstand repetitive cycles and the abrasive environment of a D.E. system without bending or corroding.
