What distinguishes our pressure intensifiers:
  • Cost-effective solution for cyclical operation
  • Pressure increase up to 4,000 bar
  • Useful for temporarily required high pressure
  • Saving energy in hydraulic systems

Operating principle of hydraulic pressure intensifiers
The secondary side can be operated with almost all fluids

General function of pressure intensifiers

In the pressure intensifier, an area A1 with the effective diameter D1 is subjected to the primary pressure p1. The resulting force generates a transmission pressure p2 (secondary pressure) on the smaller area A3 with the effective diameter D2, which corresponds to the area ratio.

Function and use in test applications

With a servo-hydraulically driven hydraulic cylinder (primary cylinder), any desired travel profile of the piston rod can be generated. This travel profile generates any desired pressure curve in the high-pressure chamber, which can be applied to a test object as a test pressure.

Components can be pulsed with internal pressure, for example, which is ideal for burst tests on hollow bodies such as hoses, pipes and tanks. The test cylinder can be operated with hydraulic oil, while the high-pressure section works with environmentally friendly fluids such as water.
In the pressure intensifier, an area A1 is subjected to the primary pressure p1. The resulting force generates a translation pressure p3 (secondary pressure) on the smaller area A3, which corresponds to the area ratio.

All sizes and pressures of the pressure booster on request.
* The dynamic limits depend, among other things, on the stroke or stroke volume of the pressure intensifier and on the amplitude of the secondary pressure p2. These data have an influence on the service life via the fluid compression and pressure rise times and must be calculated in the application.

Questionnaire
Pressure intensifier
To design a pressure intensifier for a defined stroke and delivery volume, information on the fluid and secondary pressure is required.
