About This Item

The Pentair Challenger Mounting Plate (355317Z) is the OEM replacement mounting plate for the Challenger, Pinnacle High Pressure, and WaterFall™ Specialty Inground pump lines.

What It Does

The mounting plate secures the motor assembly to the pump housing, maintaining precise alignment between the motor shaft and pump components. Replacing a damaged or corroded mounting plate restores the structural integrity of the pump assembly and prevents vibration-related wear on connected components.

Specifications

Pentair Part Number 355317Z
Also Known As 355317
Description Challenger Mounting Plate — .75HP–3HP FR HH
Quantity Included 1

Pro Tip

Match the part number stamped or molded on your existing mounting plate to 355317Z before ordering. When the pump is disassembled for a mounting plate replacement, inspect the motor bracket and shaft seal at the same time — replacing worn components together avoids a repeat teardown.

For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
