Hydraulic Breaker Spare Parts
Diaphragm

The diaphragm works between the gas (N₂) chamber and the hydraulic side, contributing to the energy storage-return cycle.

It is made from material resistant to high temperature and pressure; the right hardness and geometry determine impact efficiency.

Features

  • Material resistant to high temperature/pressure
  • Precise geometry for a stable energy cycle
  • Reliable sealing at the gas-hydraulic boundary
  • Full OEM compatibility

Frequently Asked Questions

What does the diaphragm do?

It separates the gas (N₂) chamber from the hydraulic side and contributes to the piston’s return energy, maintaining impact efficiency.

Are diaphragms under warranty?

Diaphragms are consumable (wear) parts continuously exposed to high pressure by the nature of operation; for this reason they are outside warranty coverage.

When will my order be delivered?

In-stock items ship fast; orders within Türkiye are usually delivered within 7 business days. Parts not in stock are produced in below-market lead times.

Can’t find the part you need?
