Overview

The Aqualon 11622 – Check Valve Nut – Replaces OMAX 303293 is the threaded retaining nut used in the check valve assemblies of legacy OMAX and MAXIEM direct-drive pumps. It secures the internal check-valve components in their proper axial position and ensures the sealing elements remain correctly compressed under high-pressure cycling.

Purpose / Why It Matters

The check valve nut maintains structural integrity within the valve body. If worn, damaged, or improperly seated, it can lead to internal misalignment, seal leakage, or unstable valve operation. Replacing the nut ensures the valve stack is held firmly in place, supporting reliable sealing and consistent pressure performance.

Compatibility

This part replaces OMAX 303293 and is compatible only with legacy OMAX direct-drive pumps and MAXIEM direct-drive pumps that specifically list this OEM number.
No EnduroMAX compatibility is implied.

When to Replace / Service Indicators

Replace the check valve nut when:
• Internal valve components shift or show uneven wear
• The valve leaks despite new internal seals
• The nut threads show wear, galling, or deformation
• The check valve is being rebuilt during scheduled maintenance

Common Uses

• Securing the internal components of inlet and outlet check valves
• Restoring correct valve geometry and sealing reliability
• Completing full check-valve rebuilds in production environments
• Maintaining long-term pressure stability in the wet-end

Why Choose Aqualon

The Aqualon 11622 provides a verified dimensional match to OMAX 303293, ensuring proper thread engagement, secure retention of internal components, and reliable sealing performance in legacy OMAX and MAXIEM direct-drive pump check valve assemblies.
