Diaphragm HP

Made for professional drill-rig and drifter maintenance, the Diaphragm HP (OEM 91-0903-03) is positioned as a reliable aftermarket alternative for the hydraulic power and control circuit. It supports the pressure-balancing function of the circuit, helping absorb pulsation and manage short-duration energy demand around the connected hydraulic system.

The alternative sourcing option is suited to maintenance programs focused on equipment availability, predictable servicing and competitive lifecycle cost. Listed compatible equipment includes DNT3-IIIK-E. Verify the exact machine variant before installation or ordering. Dimensional control at the pressure interfaces supports consistent damping behavior and helps maintain separation between the working media where applicable.

Offered within Delkom’s aftermarket range for surface and underground drilling machinery, this part supports planned maintenance and international spare-parts supply. To confirm availability and fitment, reference Delkom 150 100 037 and OEM 91-0903-03 when contacting the Delkom team.
