The recycling of valuable (waste) materials is becoming increasingly important in times of increased weighting, the CO2 balance of products and companies. Together with system suppliers and end customers, ZEILFELDER Pumpen develops application-specific pump technology that meets the respective requirements. The focus here is on process stability and sustainability. Special processes often require abrasion resistance, high pressures, high temperatures, or high viscosities. The flexible orientation of the design allows correspondingly adapted sealing technology.
