ABSTRACT:
A cartridge seal having a sleeve for fitting over a pump shaft and, at one end region of the sleeve, a stationary seal whose floating component is biased towards its static component. The cartridge further includes a member longitudinally spaced from the seal, which member and the stationary seal are moveable longitudinally relative to one another. The floating component is biased away from said member and towards the static component, means being provided to limit separation of said member and the stationary seal. The invention therefore provides a complete mechanical seal in one cartridge.
