Overview
The Aqualon 11951 – Check Valve Body – Replaces OMAX 303251 is the main housing used in OMAX-style pump inlet check-valve assemblies. It provides the precision-machined internal cavity and threaded interfaces that support the check-valve seat, ceramic ball, retainer, and sealing elements.
What’s Included
Check valve body to replace OMAX 303251.
Purpose / Why It Matters
The check valve body forms the structural base of the inlet check valve. Its internal geometry must align and support the seat, ball, and retainer so the valve opens cleanly on the suction stroke and seals instantly on the pressure stroke. Wear, scoring, thread damage, or erosion inside the body can cause backflow, slow pressure rise, pressure drift, or inconsistent pierces. Replacing the body with Aqualon 11951 restores proper alignment of all internal components and ensures stable, repeatable valve performance.
Compatibility
Aqualon 11951 replaces OMAX 303251 for inlet check-valve assemblies designed to use this OEM check valve body.
No additional compatibility is claimed.
