Pentair 071734S Shaft Seal / Seal Kit – for WhisperFlo & IntelliFlo Pumps
Part # 071734S — an OEM replacement shaft seal kit designed for many Pentair pump models, including WhisperFlo, IntelliFlo, and compatible pumps from related brands. This kit helps maintain a watertight seal around the motor shaft, preventing leaks and protecting the pump’s internal components.
Key Features
- Complete seal assembly including ceramic seal and elastomeric components for a reliable fit.
- Designed to prevent water intrusion along the motor shaft, reducing risk of motor damage and leaks.
- Durable, chemical-resistant materials suited for pool water environments.
- Compatible with a wide range of pump models — WhisperFlo, IntelliFlo (various variants), Ultraflow, and several other legacy pump lines from Pentair and affiliated brands.
- Recommended to replace whenever pump is disassembled (e.g., during impeller or wet-end service) or if leaks around shaft seal are detected.
Typical Applications
Ideal for maintenance or repair of in-ground pool pumps when the original shaft seal fails, leaks, hardens, or shows wear. Also recommended as a preventive maintenance item when servicing the pump’s wet end, impeller, or motor — helps restore reliable sealing and extend pump life.
Installation & Compatibility Notes
Turn off the pump and disconnect power before servicing. Drain water from the pump housing and remove the old seal carefully. Clean sealing surfaces thoroughly and ensure shaft and seal plate are free of debris. Press the new seal assembly into place — ceramic face toward the housing, elastomeric portion seated properly. Re-assemble the pump, re-prime the system, and test for leaks or water seepage before resuming normal operation.
Why Replace the Shaft Seal?
A worn or damaged shaft seal can allow water to seep into the motor, degrade internal components, reduce pump efficiency, or cause complete pump failure. Installing a new 071734S seal ensures proper hydraulic integrity, protects the motor, and helps maintain consistent pump performance.
Maintenance Tips
- Inspect the seal during any pump disassembly or annual maintenance — replace if cracked, brittle or leaking.
- Ensure sealing surfaces are clean and dry before installing new seal to guarantee proper fit and sealing.
- Avoid contaminating the ceramic seal face with grease, oil, or debris — handle with clean gloves or cloth.
- Re-check for leaks after the pump has run for a full operating cycle, especially under prime and suction conditions.
