Overview
The Aqualon 11780 – Seal Retainer Assembly – Replaces OMAX 302948 is the complete seal-and-retainer package used in the cylinder assembly of legacy OMAX and MAXIEM direct-drive pumps. It holds the dynamic sealing components in their correct axial position and ensures proper compression and alignment within the wet end.
What’s Included (OEM-equivalent contents)
• 1 × O-Ring (Aqualon 11631, OMAX 201707)
• 1 × Dynamic Seal (Aqualon 11652, OMAX 302951)
• 1 × O-Ring (Aqualon 11633, OMAX 200377)
• 1 × Seal Retainer (Aqualon 11624, OMAX 302949)
Purpose / Why It Matters
The seal retainer assembly ensures the dynamic seal and associated O-rings are properly supported and maintained under operating pressure. Wear or distortion of this assembly can lead to poor seal compression, premature leakage, or unstable pressure output. Replacing it restores correct sealing geometry and extends the life of both the plunger and cylinder.
Compatibility
This assembly replaces OMAX 302948 and is compatible only with legacy OMAX direct-drive and MAXIEM pump models where this OEM part number is specified.
No EnduroMAX compatibility is implied.
When to Replace / Service Indicators
Replace the assembly when:
• Seal retention becomes inconsistent or seals shift out of position
• Leakage persists after installing a new dynamic seal
• The retainer shows signs of wear, damage, or deformation
• Pressure stability declines despite healthy check-valve and plunger components
Common Uses
• Restoring correct seal support during routine wet-end maintenance
• Rebuilding cylinders that show uneven seal wear
• Preventing premature failure of new dynamic seals
• Completing full seal and retainer replacement during minor or major pump service
Why Choose Aqualon
The Aqualon 11780 provides a fully verified replacement for OMAX 302948, matching the exact seal and retainer configuration required for proper wet-end sealing and long-term reliability in legacy OMAX and MAXIEM direct-drive pumps.
