Product Overview

The Pentair SuperFlo Pump Housing 350089 is a genuine OEM replacement volute housing designed for select Pentair SuperFlo pool pumps. This housing forms the main water chamber of the pump, helping direct water flow from the suction inlet through the impeller and out to the discharge port.

This replacement housing is ideal when the original pump housing is cracked, leaking, warped, stripped at the ports, or damaged from freeze expansion, over-tightened fittings, or equipment pad wear. Replacing the housing can help restore proper pump operation without replacing the complete pump.

Benefits

The Pentair 350089 helps restore the main wet-end body of compatible SuperFlo pumps. If the housing is cracked, leaking, or damaged, the pump may lose prime, leak water, pull air, or fail to move water efficiently.

Using an OEM Pentair replacement housing helps ensure correct fitment with compatible SuperFlo parts, including the lid assembly, basket, seal plate, diffuser, impeller, and plumbing connections. This makes it a strong repair option when the motor and other pump components are still serviceable.

Specifications

Customer-Facing Q&A

What does the Pentair 350089 replace?
The Pentair 350089 replaces the main pump housing/volute on compatible Pentair SuperFlo pump models.

Is this a complete pump?
No. This is the replacement housing only. It does not include the motor, seal plate, impeller, diffuser, lid, basket, clamp, or other pump components unless specifically stated.

Which pumps does this fit?
This housing is commonly listed for Pentair SuperFlo pump models, including select SuperFlo, SuperFlo VS, and SuperFlo VST pumps. Always confirm your exact pump model before ordering.

Does this fit by horsepower?
No. Pump housings should not be ordered by motor horsepower alone. Confirm the pump model number and wet-end design before ordering.

When should I replace the pump housing?
Replace the housing if it is cracked, leaking, warped, damaged at the plumbing ports, or no longer sealing properly with the pump lid, seal plate, or plumbing.

Does this include the drain plugs?
Listings vary. Unless specifically stated, this should be treated as the housing only and drain plugs or O-rings should be confirmed separately.

Is this an OEM Pentair part?
Yes. This is a genuine Pentair OEM replacement pump housing/volute.

Confirm Before Ordering

Confirm your exact pump model and existing part number before purchasing. This housing is commonly used with Pentair SuperFlo pump models, but compatibility can vary by pump version, wet-end style, and production date. Do not order based on motor brand, motor horsepower, or pump appearance alone.

For best repair results, inspect the lid O-ring, seal plate O-ring, shaft seal, diffuser, impeller, and drain plugs while replacing the housing. Always shut off power, relieve pressure, and have pump repairs performed by a qualified pool professional when needed.
