kelmado Wet End Replacement Kit for Pentair 357149 — Fits WhisperFlo & IntelliFlo 0.5–2 HP, Complete Housing & Seal Plate

kelmado's Complete Wet End Replacement Kit restores a failed Pentair 357149 wet end—delivering a full housing, seal plate, basket, and all hardware needed to revive WhisperFlo or IntelliFlo pool pumps 0.5–2 HP.

If your pool pump is leaking, noisy, or losing pressure but the motor still runs, replacing the wet end can bring the system back to reliable operation at a fraction of motor-replacement cost. This kelmado kit is designed to match OEM fit and function for Pentair 357149 models and compatible WhisperFlo and IntelliFlo variants, bundling the most commonly worn components so you can complete a repair in one visit to the garage.

What parts are included and why do they matter?

The kit combines the wet end housing and all internal parts that typically fail first: the seal plate and shaft seal, diffuser and O-ring, pump basket, pot lid and locking ring, plus base inserts, screws and unions. Each component is selected to restore the pump's hydraulic integrity and prevent leaks.

• Complete housing (WhisperFlo-style) to replace cracked or warped pots
• Seal plate and shaft seal to stop shaft-side leaks and maintain shaft alignment
• Diffuser, O-ring, pump basket, and lid with locking ring for secure water flow
• Hardware kit, foot inserts, pot screws, and unions for an all-in-one swap

How simple is the installation for a homeowner or technician?

The kelmado wet end kit is made for straightforward assembly using common hand tools and follows the same attachment points as the original Pentair components. Clear part-for-part replacements reduce guesswork, making the process faster for experienced techs and achievable for handy owners comfortable with basic mechanical work.

• OEM-style dimensions minimize fit adjustments or machining
• Pre-matched seals and O-rings save time compared with sourcing parts separately
• Full hardware pack avoids interrupted projects due to missing screws or inserts
• Instructions included or available from kelmado support if needed

Which pumps and models is this kit compatible with?

This wet end replacement targets Pentair part 357149 and is compatible with WhisperFlo high-performance models and a range of IntelliFlo variable- and fixed-speed pumps in the 0.5–2 HP range. Always confirm your pump’s model number before ordering to ensure correct fit.

• Direct replacement for Pentair 357149 wet end assemblies
• Fits WhisperFlo high-performance and energy-efficient designs
• Compatible with IntelliFlo VS and VF models within the specified horsepower range
• Not suitable for pumps with different wet end footprints—verify model number first

What performance improvements can I expect after installing this kit?

Replacing a worn or cracked wet end restores proper hydraulic flow and pressure, reduces cavitation and vibration, and eliminates water leaks at the pump pot and shaft. While the motor performance remains the same, you’ll typically notice steadier pressure readings and quieter operation after a correct wet end repair.

• Improved pressure and consistent circulation through restored seals and diffuser
• Reduced noise and vibration from properly aligned housing and shaft seal
• Lower leak risk thanks to new O-rings, lid, and locking ring
• Cost-effective alternative to full pump or motor replacement
