product introduction

The pneumatic hydraulic pump is a high-pressure pump designed to increase fluid pressure, suitable for air, water, and chemical media. The pump operates at pressures up to 600 MPa, and the driving pressure ranges from 0.1–0.8 MPa (14.5–116 PSI). It is ideal for applications requiring high pressure, such as oil and gas, chemical, mining and aerospace industries.

Product Description

The pneumatic hydraulic pump increases the pressure of air or liquid proportionally, delivering pressures up to 600 MPa (maximum operating pressure 1 MPa). The pump features a compact design with two main components: a gas-driven piston and a liquid-driven piston. The system uses air to pressurize the liquid, suitable for industrial applications that require high-pressure hydraulic fluid. The pump’s reliability and efficiency are guaranteed by its robust construction, incorporating advanced sealing technology.

The pump’s operational efficiency is achieved through a precisely engineered mechanism that minimizes energy consumption while maintaining stable output pressure.
