Pentair 357199Z Clamp, Cam and Ramp for WhisperFlo and IntelliFlo Pumps

The Pentair 357199Z Clamp, Cam and Ramp is a genuine replacement lid clamp used on compatible Pentair WhisperFlo and IntelliFlo pool pumps. This almond-colored plastic lock ring secures the clear pump lid to the strainer pot, helping maintain a proper seal while the pump is operating.

This part is commonly replaced when the original clamp is cracked, broken, stripped, difficult to tighten, or no longer holds the pump lid securely in place. A properly functioning lid clamp helps prevent air leaks, priming issues, and water leakage around the pump lid.

• This part is not for IntelliFlo3 pump models.
• Always verify your complete pump model and existing lid style before ordering.

Installation Notes

• Turn off power to the pump before removing the lid clamp.
• Relieve system pressure before opening the pump lid.
• Inspect the clear lid and lid O-ring before installing the new clamp.
• Clean debris from the strainer pot sealing surface before reassembly.
• Use only pool-safe silicone lubricant on the lid O-ring when needed.
• Do not overtighten the clamp, as excessive force can damage the clamp or lid.

Maintenance Tips

• Keep the pump lid, O-ring, and clamp threads free of dirt, sand, and debris.
• Replace the lid O-ring if it is flattened, cracked, stretched, or causing air leaks.
• Do not use petroleum-based lubricants on pool pump O-rings.
• If the pump is losing prime, inspect the lid clamp, lid O-ring, drain plugs, and suction-side plumbing for air leaks.
• Replace a cracked or damaged clamp immediately to prevent poor sealing and pump priming issues.
