Pentair 355318Z Strainer Basket

Part Number: 355318Z

Description

A genuine replacement strainer basket designed to fit compatible Pentair and PacFab pump models. It helps protect the pump and filtration system by capturing debris before it enters the impeller housing or pump wet end.

Compatibility & Fitment

  • Fits Pentair PacFab “Challenger” high-flow and high-pressure pumps.
  • Also fits Pentair WaterFall specialty pump models (AFP-75, AFP-120) and other compatible series requiring this basket size.
  • Used when the original basket is cracked, warped, missing handles, or showing excessive wear leading to flow restriction or debris bypass.

Features & Specifications

  • Top ring outside diameter: approx. 5 ⅜″
  • Height: approx. 6 ¾″.
  • Durable plastic construction designed for chemical and sunlight exposure.
  • OEM-grade fit for seamless drop-in replacement.

Installation Notes

Turn off pump and relieve pressure. Remove the pump lid and original strainer basket. Clean the strainer pot cavity of debris. Insert the new 355318Z basket, ensure it sits properly in the pot and the handle is accessible for removal. Reassemble the lid and restore circulation. Confirm normal flow and absence of bypass debris.

Maintenance Tip

Inspect the strainer basket during routine service visits. Replace if you observe cracks, missing handles, excessive debris accumulation, or decreased flow despite cleaning. Proper basket function helps extend pump and filter life by reducing the entry of large particulates.
