Kolasina Volute Pump Housing Replacement for Pentair SuperFlo - 350089 Corrosion-Resistant Direct-Fit Shell

The Kolasina 350089 volute pump housing is a direct-fit replacement shell for Pentair SuperFlo pumps that restores water flow and protects internal components from corrosion.

When a cracked or worn pump housing reduces circulation or leaks, swapping in a sturdy replacement shell is often the fastest, most cost-effective fix. This Kolasina unit is made from high-strength, corrosion-resistant material and is manufactured to match the mounting points and ports of common Pentair SuperFlo models so you can reinstall quickly and return your pool or spa system to reliable operation.

Will this housing fit my Pentair SuperFlo pump model?

Yes — the 350089 housing is designed to be compatible with a range of SuperFlo variable-speed and single-speed models. Confirm your pump’s model number against the compatibility list to ensure a direct fit before ordering.

• Compatible models: SuperFlo VST Variable Speed (342002), SuperFlo VS 1.5HP (EC-342001)
• Also fits select SuperFlo TEFC and high-performance units (e.g., 348190, EC-348190)
• Check visual mounting points and port orientation against your existing housing

How does the material improve pump longevity?

The replacement shell uses a durable, corrosion-resistant compound meant to withstand continual exposure to chlorinated water and common pool chemicals. That resistance reduces the chance of pitting, cracking, or early failure compared with lower-quality housings.

• High-strength construction resists mechanical stress and impact
• Chemical-resistant formulation lowers degradation from sanitizers
• Designed to maintain sealing surfaces and threaded connections over time

How difficult is it to install this volute housing?

The part is engineered for straightforward replacement using standard hand tools; many DIYers can complete the swap without specialized equipment. Still, follow safety steps and consult your pump manual to avoid misalignment or seal damage during installation.

• Direct-fit mounting holes align with Pentair SuperFlo models listed above
• No special tools required beyond common wrenches and screwdrivers
• Replace gaskets and fasteners as recommended to ensure leak-free operation

What performance benefits can I expect after replacing the housing?

Installing a properly sized, intact volute shell restores the pump’s designed hydraulic path, which helps re-establish correct suction and flow characteristics. A good housing also protects the impeller and internal components so the whole system runs more efficiently and reliably.

• Improved water intake and steady flow rates when properly assembled
• Protects internal pump components from debris and chemical exposure
• Helps maintain motor load and energy performance by preventing leaks

Who is this for: Pool and spa owners, maintenance professionals, and contractors who operate Pentair SuperFlo pumps and need a dependable replacement volute shell. This Kolasina 350089 housing is aimed at anyone seeking a durable, cost-effective repair that matches original mounting and flow geometry, and who prefers a straightforward installation backed by a two-year warranty from the seller.
