700 Bar High-Pressure Hydraulic Cylinders | Hollow Plunger Cylinders

When an application requires high force in a compact design, high-pressure hydraulic cylinders provide a controlled way to lift, push, or pull loads. Hollow plunger hydraulic cylinders rated for pressures up to 700 bar (approximately 10,153 psi) are particularly useful when a rod, threaded connection, or other suitable component must pass through the center of the piston.

Hidroman offers hollow plunger hydraulic cylinder options with steel and aluminum body designs, different force capacities, and multiple stroke lengths for industrial maintenance and other demanding applications.

What Is a 700 Bar Hydraulic Cylinder?

A high-pressure hydraulic cylinder converts hydraulic fluid pressure into mechanical force. Depending on its design and the application, it can be used to lift equipment, apply force, pull components, or perform controlled mechanical operations.

A working pressure of 700 bar is equivalent to 70 MPa or approximately 10,153 psi. Every component in the hydraulic circuit—including the pump, hoses, couplings, fittings, and cylinder—must be suitable for the intended operating pressure.

A hollow plunger cylinder has a central opening through the piston. This design allows a compatible rod or connection component to pass through the cylinder, making it useful for certain pulling, tensioning, and maintenance applications.

Benefits of Hollow Plunger Hydraulic Cylinders

High Force in a Compact Design

High hydraulic pressure can produce substantial force when combined with the appropriate effective piston area. This makes high-pressure cylinders useful when installation space is limited but significant lifting or pulling force is required.

Central Opening for Pulling and Tensioning Applications

The hollow piston design accommodates a compatible rod or connection component through its center. Depending on the setup, this configuration can support pulling, tensioning, and selected mechanical removal operations.

Spring Return

Selected models feature spring return, which helps retract the piston when hydraulic pressure is released. Return performance and operating-cycle suitability should be verified against the specifications of the selected model.

Steel and Aluminum Body Options

Steel and aluminum models can be considered according to application requirements. Aluminum cylinders can offer a weight advantage in portable applications, while the intended load, usage frequency, and operating conditions remain important selection factors.

Hidroman 700 Bar Hydraulic Cylinder Features

The hollow plunger cylinder range listed on Hidroman's product page includes the following features:

• Maximum working pressure: 700 bar

• Cylinder design: Hollow plunger hydraulic cylinder

• Body materials: Steel and aluminum options

• Piston surface: Hard chrome plated

• Return mechanism: Spring return on applicable models

• Construction: Hardened cylinder head

• Connection: 3/8"-18 NPT quick coupling on models specified in the product information

• Selection: Different force capacities and stroke lengths

Depending on the model, the listed range includes force capacities of 12, 22, 30, and 60 metric tons. Confirm the exact stroke, dimensions, body material, and connection type using the technical specifications for the selected model before ordering.

Aluminum-body models can reduce equipment weight. However, the manufacturer's product information states that these models may not be suitable for long-duration applications involving high repetition rates.

Applications for High-Pressure Hydraulic Cylinders

When correctly selected and integrated into a suitable hydraulic system, 700 bar hollow plunger cylinders can be considered for applications such as:

• Controlled lifting of heavy equipment

• Industrial machinery maintenance and installation

• Mechanical pulling and tensioning

• Component removal and assembly with suitable tooling

• Industrial maintenance workshops

• Machinery and equipment service operations

• Portable high-pressure hydraulic systems

The required force, stroke, mounting arrangement, and method of supporting the load must be established for each application. Selecting a cylinder with sufficient rated force does not, by itself, guarantee a safe lifting or pulling operation.

How to Select the Right High-Pressure Hydraulic Cylinder

Several technical factors should be reviewed before selecting a cylinder.

1. Required force: Determine the load, load distribution, and force required for the operation.

2. Stroke length: Match the cylinder's available travel to the required movement and installation space.

3. Hollow plunger dimensions: Verify the center opening and compatibility with the intended rod, threaded connection, or tooling.

4. Body material: Consider portability, usage frequency, mechanical loading, and the operating environment when evaluating steel and aluminum options.

5. Hydraulic power source: The pump must support the required operating pressure and provide sufficient hydraulic fluid volume for the cylinder.

6. Hoses and connections: Hoses, couplings, adapters, and other pressure-containing components must be rated for the intended system pressure.

7. Return mechanism: Confirm whether spring return meets the application's operating and retraction requirements.

High-Pressure Hydraulic Safety

Hydraulic pressure at 700 bar can cause severe injury and equipment damage. The cylinder, pump, hoses, couplings, and fittings must be compatible with the intended pressure, and the manufacturer's operating and safety instructions must be followed.

During lifting operations, loads must be secured using appropriate mechanical supports. Personnel must remain clear of suspended or inadequately supported loads, and equipment must be operated within its specified capacity. Hydraulic pressure alone must never be treated as mechanical load support.

Any manufacturer restrictions on operating frequency, including those applicable to aluminum-body models, should also be observed.
