Unloading Diaphragm

The Unloading Diaphragm (OEM 2635 3171 97) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. It is a precise internal part of the percussion or valve mechanism, managing the controlled motion and energy transfer behind drilling performance.

Made from hardened, precision-ground alloy steel, it endures high cyclic impact and pressure while keeping tight clearances and accurate operation. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.

Delkom manufactures the world’s highest-quality alternative rock drilling, drifter equipment and spare parts, exported to more than 100 countries. Contact us for availability, bulk pricing and technical support.
