Product details

The Pentair 355320Z is the complete band clamp assembly for the Challenger high flow and high pressure inground pumps and the WaterFall Specialty pump. It is the genuine Pentair part, supplied whole.

What it holds

The band clamp pulls the front housing against the seal plate and holds that joint tight. Everything sealing at that face depends on the clamp being able to draw down evenly, which is why a distorted band or seized hardware turns into a persistent leak that no amount of tightening fixes.

When to change it

Band clamps live outdoors, wet, and often on a pad that gets splashed with chemicals. Corroded bolts and rusted bands are a normal find once a Challenger is opened for service. If the old clamp will not torque evenly or the hardware is fighting you, replace the assembly while the pump is already apart.

Questions and answers

What people ask about this product, answered by our pool techs.

Is this the complete clamp?
Yes. Pentair 355320Z is the complete band clamp assembly, not just the band or just the hardware.
Which pumps does it fit?
The Pentair Challenger high flow and high pressure inground pumps, and the WaterFall Specialty pump.
What does the band clamp do?
It clamps the front housing to the seal plate. If it will not tighten evenly, or the hardware has corroded, the joint leaks.
Should I replace it during a rebuild?
If the band is distorted or the hardware is seized or rusted, replace it. A clamp that cannot be torqued properly will leave you chasing a leak at the housing joint.
