Cartridge seals consist of a modular design, balanced, multiple spring, O-ring mounted seal, with various bolt holes and flush port combinations. Their construction eliminates the need to measure and set spring compression, and having a mechanical seal pre-assembled means that the seal faces are protected from damage during installation.

Fitting errors are significantly minimised by the Self-Aligning Stationary Faces and minimal internal/external Gland protrusion. Mechanical Seal lifetime is highly improved and maintenance frequency is greatly reduced. All three types listed eliminate shaft fretting and also guard against the clogging of seal faces and springs.
