ABSTRACT:
A mechanical seal for pressurized fluid pumps including rotary and non-rotating seal members that are compressed together. The rotary seal member is fixed to a drive shaft and includes a contact sealing surface. The non-rotational seal member is also positioned about the drive shaft in a manner that allows for axial but not rotational movement. When a biasing force is placed against one side of the non-rotational seal member the opposite side, the non-rotating contact sealing surface, is pressed into contact with the complimentary rotary seal member contact sealing surface thus providing a mechanical seal.
