Hydraulic booster units. Ready-to-connect units to increase the existing pressure for hydraulic applications.
Hydraulic
Compressed Air Boosters
Poppe + Potthoff Maschinenbau GmbH supplies compressor units, air amplifiers, nitrogen charging stations and pressure control systems of up to 400 bar for various gases. Thus, we offer ready-to-connect units to increase the existing pressure for pneumatic and hydraulic applications. In this way, the performance of existing systems can be increased flexibly and efficiently. Our compressor units are used wherever the existing system pressure is insufficient to implement specific applications. Air Amplifiers are suitable for the compression of pressurised air or nitrogen, while our boosters can be used for various kinds of testing and filling, recovery of gases or for other functions requiring high pressure.
High-pressure valve
In addition to technical challenges in pressure generation, applications in high-pressure technology often require special high-pressure valves with the desired properties which are only very rarely available in the market. For this purpose, Poppe + Potthoff Maschinenbau GmbH develops and manufactures high-pressure valves for the control and regulation of volume flows in hydraulic applications. The valves are pneumatically or electrically controlled.
Performance Data
High-pressure hydraulic units for oils
Poppe + Potthoff Maschinenbau GmbH supplies ready-to-connect hydraulic units up to 4,000 bar. A pneumatically driven piston pump is used for pressure generation. The pump is simply connected to the existing domestic air supply network. Accordingly, no electrical connection is necessary for the construction of the pressure. Our hydraulic units are available in various pressure stages and are used, for example, in hydraulic clamping systems.
The desired operating pressure is set at the hydraulic units by means of a pressure reducer on the pneumatic drive side. The transmission ratio (e.g.: 1:600) provides the desired operating pressure. For example, a 5-bar inlet pressure corresponds to an operating pressure of 3,000 bar. When the desired high pressure is reached, the pump stops automatically and thus no longer consumes energy.
A shut-off valve allows the separation of the unit and pressure output. The expansion valve also allows the pressure to be released into the tank.

High-pressure hydraulic units for water
In addition to the classic oil hydraulic units, Poppe + Potthoff Maschinenbau GmbH also supplies ready-to-connect water hydraulic units of up to 4,000 bar. The design of the units is largely identical to the oil hydraulic units. Water hydraulic units serve, for example, as a drive medium for washing pumps in machine tools. These systems are also available at various pressure levels and require only compressed air from the domestic air supply network as the drive medium.
The desired operating pressure in the hydraulic units is set by means of a pressure reducer on the pneumatic drive side. The pressure ratio (e.g.: 1:600) produces the desired operating pressure. For example, a 5-bar inlet pressure corresponds to an operating pressure of 3,000 bar. When the desired high pressure is reached, the pump stops automatically and thus no longer consumes energy.
A shut-off valve allows the separation of the unit and pressure output. The expansion valve also allows the pressure to be released into the tank.

Mobile pressure regulation systems
With the mobile pressure unit/pressure truck, a hydraulic pressure of up to 4,000 bar can be generated. Hydraulic supply and pressure translators are designed to customer requirements. The oil is filtered and passed via quick couplings to the proportional valve, which is mounted directly on the pressure translator and regulates the pressure build-up according to the defined specifications. The high-pressure section consists of three high-pressure valves with a pneumatic drive. Calibration connections are accommodated on the pressure transmitter. The high-pressure accumulator is equipped with a 2/2-way valve, accumulator, safety valve, manometer, storage relief valve and a pressure switch with a digital display.
The mobile pressure unit, therefore, is a compact and automatic operating system for pressure generation and control, taking into account customer-specific media and purity classes.

PRESSURE TEST BENCHES AND APPLICATIONS
PRECISE, REPEATABLE AND RELIABLE
As a specialist in pressure testing technology and state-of-the-art test rigs, Poppe + Potthoff Maschinenbau supports the development and production of particularly resilient components made of various materials – especially for automotive, shipbuilding and mechanical engineering as well as fluid and the medical industry. We offer individually designed test benches such as burst pressure test rigs, pressure cycle test benches, leak test systems, functional test rigs and autofrettage systems.
Pressure change test stand with vacuum testing
Subject cooling systems of ECUs, PTC heaters, high-voltage coolant auxiliary heaters, ACDC and DCDC converters, and other media-carrying components to pressure tests while controlling the ambient and media temperature of, for example, water-glycol at temperatures from -40 °C to 140 °C.
Function test stand: battery simulation under the influence of temperature
For functional testing of media-carrying components, a temperature-controlled volume flow (e.g. 30l/min) can be generated with the Poppe + Potthoff test benches. In addition, a component from e-mobility can be energized if required.
Leakage test stand
Poppe + Potthoff leak test stands can be used to test various components and assemblies for leaks by means of a pressure drop. Depending on the test requirement, our systems can be designed including vacuum unit and low pressure or high pressure module for optimal leak testing. In addition, Poppe + Potthoff offers e.g. bubble tests in a water bath / underwater tests with air and gas.
