Establishes the minimum electromechanical requirements for sealing systems for centrifugal and rotary pumps with seal sizes from 30 millimeters to 120 millimeters (1.5 to 4.5 inches). It also provides a standard seal design that has been tested and qualified under the service conditions for which it is intended to operate. In addition, this standard encourages evolving technology through qualification testing, data sheet input, and for engineered seals.
