Pneumatic hydraulic pump for hydraulic clamping device

The air-driven hydraulic pump uses ordinary compressed air as the power source, generating high-pressure hydraulic force at the small piston end through low-pressure air at the large piston end, capable of producing up to 70MPa hydraulic pressure. Compared to traditional electric hydraulic pumps, it offers specific advantages in certain applications: 1. No power supply required, no sparks, energy-saving, and cost-effective. 2. High output pressure, capable of achieving 70MPa hydraulic pressure. 3. Enhanced clamping functionality: The product comes with a built-in check valve, automatically maintaining pressure once the set pressure is reached; if the power air source is not cut off, it can also automatically replenish pressure to prevent pressure leakage and ensure effective clamping. 4. Environmentally friendly usage, with low decibel levels during operation (less than 75dB). Once the set pressure is reached, it automatically maintains pressure and stops operation, achieving a zero-decibel state. 5. High output pressure accuracy with stepless adjustment. Adjust the compressed air pressure steplessly to achieve stepless output hydraulic pressure. 6. Compact size and lightweight, with a net weight of 2.5 kg. 7. Easy installation and use, featuring three connection ports: one air inlet, one liquid inlet, and one liquid outlet. The product has an automatic liquid suction function, so simply controlling the air inlet allows for operation start/stop and output pressure adjustment. 8. Simple structure and easy maintenance. The product has fewer seals and components, combined with its lightweight and compact design, making installation, operation, and maintenance highly convenient.
