Poppe+Potthoff Maschinenbau GmbH

What Poppe+Potthoff Maschinenbau GmbH does

Poppe+Potthoff Maschinenbau GmbH is a German Tier-1 industrial manufacturer and wholly-owned subsidiary of Poppe+Potthoff GmbH, focused on high-pressure test benches, autofrettage systems, and special-purpose machinery for component testing. The company was founded in 1928 in Werther, Westphalia, and its Maschinenbau entity operates from Nordhausen, Germany. It sells directly to global OEMs and Tier-1/2/3 suppliers across automotive, heavy duty, off-highway, machinery, marine, defense, aerospace, infrastructure, and e-mobility customers through enterprise field sales, supported by 13 locations in 8 countries (Germany, Hungary, Czech Republic, Slovakia, Italy, China, India, United States) and more than 1,300 employees worldwide.

The company's product portfolio spans precision steel tubes, precision turned parts for braking, injection, safety, and transmission systems, Common Rail high-pressure injection lines for diesel and gaseous media, precision and industrial couplings (via subsidiary R+W Antriebselemente), and a dedicated hydrogen business under the TOPAQ brand. The TOPAQ modular hydrogen distribution system includes an On-Tank Valve, Parallel Charging Unit (PCU), High Pressure Regulation Unit (HPRU), H2 high-pressure pipes, and thermal pressure relief devices, all built around the company's proprietary PPH2 material with ISO 2974/13296-compliant metal-to-metal sealing. On the equipment side, Maschinenbau produces autofrettage systems for fatigue-life enhancement of pressure vessels, burst pressure, leak, impulse, and functional test stands, plus a newer line of e-mobility test stands covering pressure/temperature cycling (-40 to +140°C) and high-voltage functional testing up to 600VDC/150A. Multiple granted patents cover the TOPAQ hydrogen architecture.

The business model is B2B hardware sales with project-based, non-publicly-disclosed pricing negotiated per customer. Revenue streams include precision metal components, hydrogen systems under the TOPAQ brand, and testing/measurement equipment. The go-to-market is enterprise field sales targeting global OEMs, reinforced by high-visibility engineering partnerships such as the JCB Hydromax hydrogen land speed record project for Bonneville SpeedWeek 2026, a multi-language digital presence (7 languages), and participation in industry events. The company is IATF 16949 certified, holds consecutive Top Innovator recognition from Germany's TOP100 competition (2023, 2025), and is managed by Markus Kerkhoff, Haluk Mehmet, and Marco Schmidt. No revenue, funding, or M&A data is publicly disclosed.
