Cartridge seals embody the modern form of mechanical seal designs. They contain all the required sealing elements in a unitary, pre-set and pretested assembly.
They were developed to facilitate professional, error-free mounting of seals on rotary fluid machines, mostly centrifugal pumps. Ettem catalogue cartridge seals are available in metric as well as imperial size range from 25mm (1″) to 100mm (4″), for standard or oversize seal chambers and are offered in standard or special material combinations
