Milestones

AERZEN looks back on an eventful history. Whether Wilhelm Meyer, who was the first on the continent to have positive displacement blowers made using the Roots method, Hermann Allstaedt, the Managing Director during the 1930s who focused production consistently on blowers, pumps and gas meters,or Hasso Heller, who founded the first subsidiary Aerzen France in 1968 to set the company on course for internationalisation – over the last 150years we “Aerzeners” repeatedly took brave decisionsto put us a step ahead of the competition.

The new generation of rotary piston pumps at work

1926

The generation of rotary piston pumps is introduced on the market: The shape of the rotors is similar to the shape of the rotary pistons of the blowers. They distinguish themselves by symmetrical, two-lobe profiles, which enables them to convey thick as well as thin liquids.

An old rotary piston gas meter -  it was an decisive step on the path towards a special factory for positive displacement machines and thus out of the economic crisis

1930

In the difficult period of the world economic crisis in Aerzen the production of rotary piston gas meters starts, a decisive step on the path towards a special factory for positive displacement machines and thus out of the economic crisis.
