Hayward BUMP SHAFT -EC30/40/50-

The Hayward Bump Shaft for the Perflex EC30, EC40, and EC50 series is a central mechanical component designed to facilitate the "bumping" action required to regenerate the filter's Diatomaceous Earth (D.E.) coating. Manufactured from a high-strength, corrosion-resistant material, this vertical rod connects the external bump handle to the internal tube sheet assembly. Its primary mechanical function is to allow the operator to manually shift the internal tubes up and down, effectively shaking off the spent D.E. powder and accumulated debris from the filter fingers without requiring a traditional backwash cycle. This process redistributes the filter media, extending the time between full cleanings and ensuring optimal flow rates within the compact pressure vessel. The shaft is engineered with precise threading and tolerances to maintain a watertight seal where it penetrates the filter head, preventing leaks while allowing for smooth vertical movement. For shipping and logistical purposes, the estimated weight of the Hayward Bump Shaft for the EC30/40/50 models is approximately 0.85 pounds in its retail protective packaging, while the actual dry weight of the shaft itself is roughly 0.62 pounds.
