Description

Made for professional drill-rig and drifter maintenance, the Diaphragm (OEM 040212-020321) is positioned as a reliable aftermarket alternative for the rock drilling machine assembly. It forms part of the pressure-damping arrangement that helps protect the circuit from sharp pulsation and supports more stable hydraulic response.

Cross-reference data lists applications including HCR 1200-DSIII and HCR 1200-EDII; final fit should be confirmed against the machine configuration or serial information. It gives maintenance teams another sourcing path for the referenced application without compromising the need for dimensional and functional compatibility. Reliable sealing and pressure containment are important because the assembly works with rapid pressure changes generated by high-cycle drilling operation.

Delkom supplies alternative spare parts for rock drilling equipment to maintenance teams across international mining and tunneling markets. When requesting stock status, technical support or a quotation, provide Delkom part number 130 600 097 together with OEM reference 040212-020321.
