Shanghai Ellem Pneumatic Boost Hydraulic Power Unit

【Introduction】The milky-white circular core component in the center of the cover image is our company’s self-developed vane-type pneumatic motor, which operates at a standard drive air pressure of 6.2 bar and uses compressed air as its power source. The motor’s rotation drives an integrated hydraulic pressure‑boosting system, rapidly increasing the hydraulic fluid to an ultra‑high pressure of 130 MPa (as shown below), thereby delivering high‑pressure hydraulic oil to power various hydraulic torque tools, clamping fixtures, and high‑pressure testing equipment.

Core Operating Principle

1. Connect to the workshop’s standard 6.2 bar compressed air supply; the pneumatic motor rotates continuously, providing stable power;

2. The motor drives a booster pump, pressurizing hydraulic oil and easily achieving ultra-high hydraulic output;

3. The high-pressure hydraulic fluid is delivered via quick-connect fittings to hydraulic actuating tools, enabling operations such as locking, pressure testing, tensioning, and leak testing;

Key Product Advantages

1. Fully pneumatically driven, explosion-proof and safe—requires only the factory’s standard 6.2 bar air supply, with no motor or electrical circuits, making it suitable for oil and gas facilities, pressure vessels, chemical plants, and explosion-proof workshops, thereby eliminating the risk of electrical sparks.

2. High pressure multiplication ratio—low-pressure air input yields ultra-high hydraulic pressure, replacing bulky electric hydraulic pump stations; the equipment is compact and portable.

3. Compatible with high-pressure applications across multiple industries—can drive hydraulic torque wrenches, high-pressure pressure-testing fixtures, sealing and clamping mechanisms for pressure vessels, and water-pressure testing equipment for gas storage tanks.

Applicable Industry Scenarios

Pressure vessel manufacturing, pressure testing for air compressor storage tanks, shipbuilding and heavy‑industry applications, metallurgical equipment assembly, valve pressure testing, explosion‑proof chemical plants, high‑pressure machine‑tool clamping fixtures, and supporting complete‑set hydraulic workstations for export.
