The performance of our developers and the legendary durability of our machines have made Probst & Class a machinery producer with an extremely loyal group of customers.

Invented and built to last.

Probst & Class was established in 1926 by Hermann Probst and Ewald Class. The abbreviation “PUC” which is well known throughout the world, is derived from the names of the company’s founders. The first PUC colloid mill patented by Probst & Class was introduced in 1933.

We develop and produce rotor/stator systems for the wet micro-comminution, homogenizing, dispersing and de-aeration of flowable and pumpable products. We also supply vacuum de-aeration units and complete lubricant processing units.

Our modular system design gives us high flexibility. We can adapt to your special requirements quickly and competitively.
