Overview

The Aqualon 11972 – Bushing Housing – Replaces OEM 300744 is the bushing housing used within the coolant housing assembly on OMAX and MAXIEM Gen-2 pump systems. It supports the coolant-side sealing components and aligns the coolant housing with the cylinder bore.

Purpose / Why It Matters

It ensures correct cooling water routing around the plunger. If this housing becomes worn or obstructed, coolant flow can be restricted, causing plunger and seal overheating.
