Diaphragm

Developed for reliable operation during intensive drill-rig duty, the Diaphragm (OEM 550 323 39) is a compatible aftermarket component for Sandvik drill rigs and related rock-drilling equipment. The diaphragm acts as the flexible working membrane inside the valve, responding to pressure differences so the valve can open, close or regulate the associated air or fluid passage. Listed applications include DP1100, PANTERA 1500 and RANGER 600, with additional compatible models shown in the product data.

The sealing materials and profiles are selected for compatibility with the movement, pressure and fluid exposure expected at the specified installation point. Elastic response and sealing integrity are important for repeatable valve action; a worn or ruptured diaphragm can cause leakage, unstable control or loss of the intended pressure function. Controlled dimensions support correct fit and dependable function during scheduled overhaul, wear replacement or corrective maintenance.
