Putsch - String-Wound Filter Cartridges
Putsch has been manufacturing string-wound filter cartridges for many decades. The cartridges are manufactured at the German head plant in Hagen, following the highest quality requirements. In addition to the fast delivery service, Putsch can also offer its customers flexibility with regard to special requests. The string-wound filter cartridges are often used in the food industry, but also for electroplating baths, chemical and water. The application options are manifold.
At the Hagen head plant, in central Germany and in the heart of Europe, string-winding technology and with it the production of effective filter media has developed over several decades. Today, Putsch® is a leading manufacturer for string-wound filter cartridges with special filter yarn, producing the best possible filtration effect based on the special filter matrix and the fiber selection.
Each winding machine is the result of in-house development, and each string-wound filter cartridge is a unique product. The longstanding, experienced employees operate the winding machines and monitor the manufacturing process for each filter cartridge. Despite the large number of types and the many orders, the employees are able to meet even short term customer requests and keep delivery times as short as possible if a specific type is not in stock.
Best quality, a high level of flexibility and fast delivery are the guiding principles of Putsch® – we have already convinced many customers with this and want to win over many new customers in the future!
