Wear ring DURO22 for Putzmeister

The DURO22 wear ring is a component designed for use in Putzmeister concrete pumps and distribution systems. It functions as a sacrificial barrier positioned between moving surfaces or areas in direct contact with concrete and mortar, which are highly abrasive materials. By absorbing friction and material contact, this ring helps protect more complex and costly internal machine components from premature degradation.

This specific part, identified by part number 251031006, is engineered for precise fitment within Putzmeister machinery. It is intended for installation in areas such as pumping valves, cylinders, or transport piping where material flow causes significant surface stress. Proper installation ensures that the component maintains the necessary tolerances to prevent material leakage and sustain pumping efficiency during operation.

Wear rings are used in heavy machinery to manage the interface between stationary and moving parts in abrasive environments. By providing a replaceable contact surface, they allow maintenance teams to preserve the structural integrity of the primary housing and internal assemblies. Regular inspection and replacement of these rings are standard maintenance procedures to ensure the continued performance of the pumping system.
