About This Item
The Pentair Clamp Band Assembly (355320Z) is the complete OEM replacement band clamp assembly for the Challenger High Pressure inground pump, securing the pump housing halves together at the volute joint.
⚠️ IMPORTANT: COMPLETE ASSEMBLY — INCLUDES ALL CLAMP COMPONENTS
This listing is the complete band clamp assembly — all components required for a full clamp replacement are included. You are not purchasing an individual clamp band only.
The band clamp assembly holds the pump's wet end and motor housing together under operating pressure. When the clamp loosens, deforms, or the locking mechanism fails, the seal at the housing joint is compromised — resulting in leaks at the volute seam. Replacing the complete assembly restores a secure, pressure-tight joint between the pump body halves. Match the part number stamped or molded on your existing clamp to 355320Z before ordering.

Pro Tip
When replacing the clamp band assembly, inspect the volute O-ring seated at the housing joint at the same time. A damaged or compressed O-ring will continue to leak even with a new clamp in place. Address both components during the same service visit to avoid a repeat teardown.
