product introduction

The  pneumatic hydraulic pump is a high-pressure liquid intensifier designed to boost the pressure of oil, water, and chemical media. The pump uses compressed air as the driving source and converts air pressure into high hydraulic pressure through a piston amplification structure.

The ODMT pump features a compact structure, stable performance, and reliable operation. The maximum pressure can reach 600 MPa depending on the model. It is widely used in pressure testing, hydraulic component testing, and various industrial high-pressure applications.

The ODMT pneumatic hydraulic pump series includes M, MD, OS, OSD, OG, and OGD models to meet different pressure and flow requirements.

Product Description

The pneumatic hydraulic pump operates with compressed air pressure ranging from 0.1–0.8 MPa (14.5–116 PSI). The pump structure connects a large-diameter air piston with a small-diameter hydraulic piston. When compressed air drives the air piston, the hydraulic piston generates higher pressure according to the piston area ratio, achieving pressure intensification.

During operation, when the outlet pressure increases and reaches the equilibrium pressure, the pump will automatically slow down and stop working. When the outlet pressure decreases or the driving air pressure increases, the pump automatically starts again.

This working principle allows the pump to maintain stable pressure output without continuous energy consumption.

Features & Functions

  • Air Driven Operation
    The pump uses compressed air as the driving power and does not require electrical power.
  • Pressure Amplification Principle
    A large-diameter air piston and small-diameter hydraulic piston structure creates pressure amplification based on piston area ratio.
  • Automatic Start and Stop
    The pump automatically stops when outlet pressure reaches equilibrium and restarts when pressure drops.
  • Stable Pressure Output
    The pump maintains stable pressure during operation.
  • Compact Structure
    The pump features a compact and simple design suitable for integration into testing systems.

 

Product Advantages

  • High Pressure Capability
    The pump can generate very high hydraulic pressure through pneumatic drive and piston amplification.
