Pentair 350015 IntelliFlo/WhisperFlo Volute – Intelliflo 2 Vst After 2018

Pentair IntelliFlo/WhisperFlo Volute Housing

OEM replacement volute housing for Pentair IntelliFlo and WhisperFlo pumps directs water flow and holds the debris basket for reliable performance.

Features

• Genuine Pentair wet end volute housing for pump circulation. 
• Resists corrosion and pool chemical exposure. 
• Compatible with multiple pump models, including WhisperFlo and IntelliFlo variants.

Description

This OEM Pentair volute housing forms the core flow chamber of your pump, guiding water from the impeller to discharge while providing a secure seat for the strainer basket. Molded thermoplastic construction resists corrosion and continuous pool exposure. Replacing a damaged or cracked housing can restore proper operation and help maintain system efficiency. 

Pro Tip

When replacing the volute, inspect the seal plate and mechanical seal — upgrading these at the same time helps prevent leaks. Consider including a complete wet-end rebuild kit if other parts show wear.

Installation Tips

Ensure power is off, and the pump is drained before volute removal. Match OEM part orientation and check mating surfaces before reassembly. Replace gaskets and seals for best water‑tight performance. Follow Pentair service manuals and safety guidelines for proper installation.
