Purpose / Why It Matters
The seals in a direct-drive wet end experience continuous high-pressure cycling and naturally wear over time. Replacing them as a complete set restores the pump’s ability to maintain stable operating pressure, prevents internal leakage, prolongs plunger and cylinder life, and supports predictable, consistent cutting performance.
Compatibility
This kit replaces OMAX 303019 and is compatible with legacy OMAX direct-drive and MAXIEM pumps where this OEM kit is specified.
No EnduroMAX compatibility is implied.
When to Replace / Service Indicators
Use this kit when:
• Water leakage is visible at the cylinder or seal interface
• Pressure becomes unstable or drops during operation
• Seal life begins shortening between service intervals
• Inspection shows flattening, extrusion, or wear on existing seals
Common Uses
• Routine seal replacement during scheduled pump maintenance
• Restoring pump performance after extended run-time
• Preventing seal-related pressure loss in production environments
• Refreshing the wet end between minor and major rebuild cycles
Why Choose Aqualon
The Aqualon 11778 includes all verified sealing components matched to OMAX 303019, with precise Aqualon-to-OEM part mapping to ensure correct fit, consistent performance, and reliable wet-end sealing across all three cylinders of legacy OMAX and MAXIEM direct-drive pumps.
