Pressure multipliers

Pressure intensifiers use the principle of force multiplication to amplify hydraulic pressure. They generally comprise a primary and a secondary piston connected by a hydraulic fluid. When the pressurized fluid acts on the primary piston, it exerts a force on the secondary piston, generating greater pressure in the secondary circuit. The multiplication ratio is determined by the difference in surface area between the two pistons.

Pressure intensifier types

There are two main types of pressure intensifier:

• Single-acting pressure multipliers: These amplify pressure in one direction only. They are generally used in applications where return force is not required.
• Double-acting pressure multipliers: These amplify pressure in both directions, allowing the secondary piston to retract under the action of an external force. They are used in applications where controlled movement in both directions is required.

Pressure intensifiers offer many advantages that make them attractive for a variety of applications:

• Increased force: They enable higher forces to be obtained from a limited pressure source, thus extending the capacities of existing hydraulic systems.
• Increased efficiency: they reduce energy consumption by using higher pressure to do the job, thus minimizing power losses.
• Precise control: output force can be precisely controlled by regulating input pressure, enabling adaptation to specific application needs.
• Flexibility of use: They can be used with various types of hydraulic systems and are suitable for a wide range of applications.
• Reliability and durability: Made from robust materials and high-quality seals, they offer long service life.
