Diaphragm

Built around the service demands of rock drilling machinery, the Diaphragm (OEM D91145) provides an aftermarket replacement path for the rock drilling machine assembly. It supports the pressure-balancing function of the circuit, helping absorb pulsation and manage short-duration energy demand around the connected hydraulic system.

Typical listed applications include TD-51, subject to machine specification and configuration verification. For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing. Reliable sealing and pressure containment are important because the assembly works with rapid pressure changes generated by high-cycle drilling operation.

Delkom supports drill-rig and drifter maintenance with alternative components for demanding mining and tunneling applications. To check fitment, lead time or bulk pricing, share Delkom reference 160 100 139 and OEM reference D91145.
