OUR HISTORY
Reliability and continuity for your strategic development for more than 25 years.

Diener Precision Pumps was literally born with its focus on quality workmanship: More than 60 years ago, Rolf Diener's father, Oskar Diener, established Diener AG - with only one lathe and a manual drill. By offering precise, mechanically accurate and on-time work, his company eventually became one of the most successful suppliers in the field of precision engineering. Only the very best is good enough - and that's the guiding principle that Diener AG lives by. And that applies to the same extent to DPP - the company that was spun off from Diener AG more than 20 years ago.
Diener Precision Pumps shares the passion for precision and a focus on the customer with its parent company. In order to be able to offer custom solutions for the wide range of different customer issues, traditional craftsmanship, a state-of-the-art machine park and reliable engineering skills joined in. This special combination is what makes DPP so distinctive today.
In 2019, DPP joined Acrotec to take unique advantage of their manufacturing synergies. Acrotec is an independent group created by micromechanical professionals. Their main objective is to be the preferred supplier, offering a wide range of precision component manufacturing processes. Their strategy is to provide quality products « Swiss Made » to the watch-making, automotive, medical, jewelry, and aeronautic industries.
