About This Item

The Pentair 355617Z is the OEM replacement diffuser for the SuperFlo pump, covering 1/2 HP Full Rated through 3/4 HP Full Rated and 1 HP Up Rated configurations.

What It Does

The diffuser channels water from the impeller into the pump volute, converting rotational velocity into pressure. A cracked or worn diffuser reduces hydraulic efficiency and can cause the pump to lose prime or deliver reduced flow. Match the part number stamped on your existing diffuser before ordering to confirm the correct HP rating for your SuperFlo.

Specifications

Pentair Part Number 355617Z
Compatible HP Ratings 1/2 HP Full Rated; 3/4 HP Full Rated; 1 HP Up Rated
Quantity Included Each

Pro Tip

SuperFlo diffusers are HP-specific — the 1/2 HP Full Rated and 1 HP Up Rated diffusers are not interchangeable with the 1 HP Full Rated version. Before ordering, confirm the HP rating and service factor stamped on your pump's motor nameplate matches the ratings listed above. When the pump is open for diffuser replacement, inspect the impeller and shaft seal at the same time — replacing worn components together avoids a second disassembly.

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.
