Efficient Filtration Systems
for Industrial Applications
Basket strainers, cone strainers, or duplex filters – modern industrial plants place high demands on filtration performance, plant availability and energy efficiency. Our filtration solutions are designed to reliably separate foreign particles from the medium, thereby protecting pumps and plant components and extending service life.
A special feature of our systems is the flexible installation of the basket strainers, which can be mounted both horizontally and vertically. This gives designers and plant operators maximum freedom when planning new installations or retrofits. Low flow resistance, maintenance-friendly designs, and well-engineered details ensure low operating costs and high system availability.
From conical strainers / start-up sieves for plant commissioning, to cost-effective basket strainers, and up to switchable duplex filters for continuous operation – our solutions stand for quality, efficiency, and practical, industry-oriented filtration solutions.

Business
since 1980.
The history of our family business dates back to 1980. During this time, the company’s founder, Günter Waldow, began conquering the industrial valve market with his engineering office. Over the years, there has been a focus on the development, manufacturing, and distribution of strainers, basket strainers, and pot strainers in welded construction.
