Hayward ECX1110 Bump Shaft for Perflex Extended-Cycle D.E. Filters (EC65 / EC75)
The Hayward ECX1110 is a genuine OEM bump shaft used in Hayward Perflex extended-cycle
D.E. filters. This shaft is part of the internal bump/cleaning mechanism that bumps the flex-tubes to knock off
spent D.E. and debris, helping restore flow between full tear-down cleanings.
Fits / Compatibility
- Hayward Perflex extended-cycle D.E. filters: EC65, EC65A, EC75, EC75A
- Also commonly referenced on Perflex parts lists/groupings such as I_PFPPTS (verify by parts diagram)
- Pool Type: In-Ground
What It Does
- Transfers the handle/bump motion into the filters internal bump assembly
- Helps flex the internal tubes so used D.E. drops off and flow is restored
- Supports smoother, more reliable bump operation when the original shaft is worn or damaged
Common Reasons to Replace
- Bump handle action feels rough, sticks, or doesnt bump effectively
- Visible wear, bending, or damage to the bump shaft
- Internal bump parts wont align correctly during service/rebuild
- Preventive replacement during a Perflex internal rebuild
Installation Notes
- Turn off the pump and relieve filter pressure before opening the filter.
- Disassemble per your Perflex models parts diagram and replace the shaft in the bump mechanism.
- Inspect related bump components (handle linkage, washers, seals, and internal parts) while the filter is open.
- After reassembly, recharge the filter with the correct amount of D.E. for your model.

Maintenance Tips
- Bump only as recommended for Perflex filtersover-bumping can reduce filtration efficiency.
- Recharge the correct amount of D.E. after cleaning/servicing to protect the flex tubes and maintain water clarity.
- If bumping no longer restores flow, perform a full tear-down cleaning and inspect internal gaskets and bump components.
- Always depressurize the filter before opening or servicing internal parts.
