Unloading Diaphragm

Engineered around the operating needs of surface and underground drilling equipment, the Unloading Diaphragm (OEM 2635 3171 97) is an aftermarket component for the rock drilling machine assembly. The part contributes to hydraulic damping and pressure stability, reducing the effect of rapid pressure changes generated during drilling cycles.

The pressure-contact surfaces are intended to remain stable through repeated charge and discharge cycles common in drilling-machine hydraulic systems. Compatibility records include CDH 911C and ECM 580. For best results, check the part reference together with the machine model and serial data. For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing.

Supported by Delkom’s experience in alternative rock-drill and drill-rig spare parts, this component is supplied for professional mining and tunneling maintenance worldwide. For availability, pricing and an application check, quote Delkom reference 120 600 058 and OEM reference 2635 3171 97.
