Overview
The Aqualon 11779 – Dynamic Seal Assembly – Replaces OMAX 302950 is the primary reciprocating high-pressure seal used in legacy OMAX and MAXIEM direct-drive pump cylinders. It forms the moving pressure barrier around the plunger, maintaining consistent sealing as the pump cycles.
What’s Included (OEM-equivalent contents)
• 1 × Dynamic Seal (Aqualon 11652, OMAX 302951)
• 1 × O-Ring (Aqualon 11631, OMAX 201707)
• 1 × O-Ring (Aqualon 11633, OMAX 200377)
Purpose / Why It Matters
The dynamic seal assembly is essential to maintaining the pump’s working pressure. As the plunger moves through each stroke, this seal endures full operating pressure and naturally wears over time. Replacing it restores stable pressure output, reduces leakage, and prevents damage to the cylinder bore and plunger.
Compatibility
This assembly replaces OMAX 302950 and is compatible with all legacy OMAX direct-drive and MAXIEM pumps where this OEM part number is specified.
No EnduroMAX compatibility is implied.
When to Replace / Service Indicators
Replace the dynamic seal assembly when:
• Leakage occurs around the plunger
• Pressure fluctuates or drops under load
• Seal wear is visible during inspection
• Seal life shortens below normal service intervals
Common Uses
• Routine wet-end seal replacement
• Restoring sealing performance between minor and major maintenance cycles
• Stabilizing pressure output after extended use
• Preventing scoring or premature wear of plunger and cylinder components
Why Choose Aqualon
The Aqualon 11779 provides a verified, direct-mapped replacement for OMAX 302950, using the correct combination of dynamic and static sealing elements to restore full sealing performance in legacy OMAX and MAXIEM direct-drive cylinder assemblies.
