Trusted by Bosch, Parker MEggitt, Mahle, Bürkert, Vibracoustic, Pilatus Aircraft, and 300+ global manufacturers with 600+ installed Pressure Test Benches Worldwide
High-Pressure Test Benches by Application
From destructive burst tests to fatigue endurance pressure cycling. Every pressure test rig is adapted or custom-built to your specification and test standard.
Burst Pressure Testing
Custom burst test benches from 1 to 15,000 bar. Validate hoses, tubes, fittings, pressure vessels, and safety-critical components to DIN EN ISO 1402, SAE J517, and many other OEM standards.
Pressure Cycle Testing
Fatigue endurance testing with programmable trapezoid & sine pressure curves up to 6,000 bar. For automotive and e-mobility component validation, with a chiller and a climate chamber.
Leak Testing
Non-destructive tightness testing by pressure drop, vacuum, underwater bubble test, or gas sniffer. Up to 1,050 bar for helium, hydrogen (N2/H2 95/5), and nitrogen is compatible.
Function Testing
Volume flow control, media temperature conditioning, battery simulation, and pressure testing in one rig. Purpose-built for EV cooling circuit validation to VW 80000 and BMW GS 95024-3-1.
Autofrettage Machine
Increase fatigue life of high-pressure components through controlled plastic deformation up to 15,000 bar — for common rails, pump heads, injectors, and thick-walled cylinders.
Test as a Service
Burst, leak, pressure cycle, autofrettage, hydroforming, and function tests at our facility in Nordhausen — no capital investment required. Full documentation and traceability included.
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.
Bursting pressure test rig < 200 bar
To prove the quality of media-carrying components, hose lines, pipes, pressure vessels and other components are pressurized until they burst.
Autofrettage Machine
A flexible and expandable system for performing autofrettage on various components such as common rails and pump heads up to 12,000 bar.
Compressed air booster
Poppe + Potthoff Maschinenbau GmbH supplies compressor units and pressure control systems up to 400 bar. We offer ready-to-connect units to increase the existing pressure for pneumatic and hydraulic applications. This allows the performance of already existing plants to be expanded flexibly and efficiently.
Test bench for H2 components
We offer pressure testing equipment for the development and validation of hydrogen and nitrogen components. The focus is on test benches in the area of pressure cycling, burst pressure testing, and hydrostatic strength testing.
1050 Bar Helium / Nitrogen / Hydrogen
A leak test bench equipped with a pressure module up to 1050 bar, an optional integrated climate chamber and a gas sniffer (e.g. Inficon) to detect leakage on H2 components such as ontank valves, hoses, pipes, fittings, regulators, valves and fuel cell components.
Automotive
Automotive testing involves a wide range of tests. Poppe + Potthoff Maschinenbau supports the industry with state-of-the-art pressure test benches, autofrettage systems and functional test benches.
Aerospace
Test systems from Poppe + Potthoff Maschinenbau put fluid systems and components for aerospace applications to a tough test. In the service life test, they undergo millions of pressure load cycles to simulate the service life of a component.
Home Appliances
Household appliance manufacturers are aware of the importance of ensuring that their media-carrying components are leak-proof from day one and that components can withstand a pressure load higher than the operating pressure. Poppe + Potthoff Maschinenbau supports the industry with various pressure testing systems.
Medical Technology
Test benches for medical technology components from Poppe + Potthoff Maschinenbau put a wide variety of components to the test. Reliable, repeatable and accurate pressure tests and test processes ensure the quality of a component during research and development.
Shipbuilding
Marine engines are composed of components that are exposed to high pressures and require pressure testing of any kind. Cooling systems, pumps and valves of marine engines are exposed to pressure and are tested for their load capacity with pressure test benches from Poppe + Potthoff.
Oil and gas
Various components from the oil and gas industry can be tested on pressure test benches from Poppe + Potthoff. Drill pipes, tubes and (gas) valves are components that are exposed to changing pressure and temperature conditions and require pressure testing to ensure quality and safety.
Pressure Test Benches for E-Mobility –
Custom Systems for EV Component Validation
Whether ECU, ADAS module, high-voltage coolant heater, cooling module, pipe, valve, or hoses, components in EV thermal management systems must perform safely under real-world pressure and temperature cycling. Therefore, Poppe + Potthoff Maschinenbau supplies custom burst pressure test, leak test, pressure cycle test, and pressure pulsation test systems for development, validation, and series production — built to OEM requirements, including, but not limited to VW 80000 and BMW GS 95024-3-1 / M-07.
