Nitrogen Diaphragm (Part No. 3201195384) – Suitable for Epiroc RD18U Rock Drill

The Nitrogen Diaphragm, part number 3201195384, is a key component designed specifically for the Epiroc RD18U rock drill. It plays a vital role in the drill's accumulator system, helping to regulate pressure fluctuations by using compressed nitrogen to absorb and stabilize hydraulic pressure spikes during drilling operations.

Description

Constructed from high-performance, oil- and pressure-resistant elastomeric materials, the nitrogen diaphragm separates the nitrogen gas chamber from the hydraulic fluid. It expands and contracts as pressure changes, helping to maintain system balance, reduce shock loads, and prolong the service life of internal components.

Proper diaphragm function is essential for consistent impact energy, vibration dampening, and the overall reliability of the RD18U rock drill.

Key Features

• Part Number: 3201195384
