About This Item

The Pentair 355305Z is the OEM replacement pump base for the Challenger High Flow, Challenger High Pressure, and WaterFall™ swimming pool pumps. If your pump base is cracked, broken, or missing mounting integrity, this is the direct factory replacement.

Pump base includes dual radius motor support adapter which fits both 5-5/8 in. & 6-1/2 in. diameter motors.

What It Does

The pump base provides the structural foundation that secures the Challenger pump to its mounting surface. It supports the motor and wet end assembly, absorbs vibration during operation, and keeps the pump correctly aligned with its plumbing connections. A damaged or cracked base can allow pump movement that stresses unions and fittings over time.

Specifications

Pentair Part Number 355305Z
Also Known As 355305
Quantity Included 1

Pro Tip

Before ordering, confirm the part number molded into your existing pump base matches 355305 or 355305Z. The Challenger line includes several frame configurations — verifying the number on the original part ensures a correct fit. If the base is broken and the number is unreadable, cross-reference your pump's model number against Pentair's Challenger parts diagram to confirm this is the correct base for your specific pump configuration.
