Reliability and continuity for your strategic development for more than 20 years.

One thing that stands out when you are dealing with a family-owned business is the personal touch: You as the customer know exactly who you are dealing with.

This is also the case when you work with Diener Precision Pumps. The owner Rolf Diener and his dedicated staff personally guarantee the quality of their products. Another thing you can count on is continuity and reliability: At Diener Precision Pumps, our customers do not need to worry about any short-term change of course - this gives you peace of mind as we work together to find and execute a long-term strategy to meet your goals.

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.
