Keep your Pentair-style WhisperFlo® or IntelliFlo® pump operating at peak efficiency with the Swimables SW-21-151 Pump Lid with O-Ring. This clear, direct-replacement lid is designed for pumps that use the industry-reference 357151, delivering a precise, leak-resistant seal that helps preserve prime and reliable circulation.

What sets Swimables SW-21-151 apart

• Includes O-ring for a complete lid + seal replacement—ready to install straight out of the box
• Clear lid enables quick visual checks of the pump basket area without disassembly
• Direct replacement for pumps using the 357151 lid reference, ensuring compatibility and ease of swap
• Simple installation—swap the lid and O-ring during routine service for minimal downtime
• Secure, leak-resistant fit when properly installed and lubricated, reducing drips and air intrusion

Why you’ll notice the benefits

• Prevents air intrusion that can compromise pump efficiency and prime
• Enhances sealing to minimize drips and mess at the equipment pad
• Extends pump usability by replacing a worn wear component rather than a full housing
• Makes basket checks easier and less invasive—no unnecessary disassembly required

Ideal uses and scenarios

• Replacing a cracked, cloudy, or warped pump lid
• Addressing air leaks, loss of prime, or seepage around the lid
• Routine maintenance when the lid O-ring is worn or flattened
• WhisperFlo® and IntelliFlo® style pumps that rely on reference 357151 lids

Installation tips

1. Clean the sealing surface on the housing to remove debris that could compromise the seal
2. Lightly lubricate the O-ring with pool-safe silicone lubricant to ensure a smooth, even seal
3. Tighten the lid evenly—snug but not over-tightened to avoid damage to the lid or sealing surface

This SW-21-151 lid with O-Ring is a practical, cost-effective upgrade that keeps your pump sealing tight, your prime solid, and your pool running smoothly. If your system uses the 357151 reference, this direct replacement fits your WhisperFlo® or IntelliFlo® pump perfectly—and it’s designed to make routine maintenance straightforward and reliable.
