Our mixer cartridge seals can perform at lowest revolutions and sliding speeds, highest pressures, while not making any excuse in references to the running times. The seal face dimension and shapes will be adjusted for special requested mixer seals, to increase the life time of the seal. In cases where contact of the product with stainless steel is prohibited, we offer non steel or enameled parts. In high- or low temperature surroundings and -areas we have optionally cooling and heating flanges which can be integrated easily. In cases with low lubrication, shape adjustments of the seal faces and special dry running mixer seal faces can be chosen to increase the life time and performance of the seal.
