The development and production of gear pumps, filters and screen changers as well as system solutions is our passion. We manufacture high-quality and efficient solutions tailored to the requirements of our customers. We use our know-how in the fields of pumps and filtration, based on many decades of experience, to develop even more efficient and powerful products.

Reliable filtration is a guarantee for success in polymer production. The degree and rates to which they have to be filtered are constantly increasing. Therefore we are constantly improving our products and supplementing our portfolio.

With our new developments we are always setting new standards. High compactness and filter performance at constant pressure and thus high end product quality is our value proposition.


The high-performance backflush filter with continuous screen cleaning is a particularly compact, efficient and powerful unit. The uniform and constantly efficient backflush of the entire screen reduces pressure fluctuations in the system to a minimum and enables the use of regrind in highly sensitive applications, such as blown film extrusion.
