Standard Specification for Mechanical Seals for Shipboard Pump Applications

ABSTRACT
This specification covers mechanical end-face seals for centrifugal and positive displacement pumps for shipboard use. Mechanical seals shall be classified by type, grade, and class. Types: type A - inside single mounted seals, type B - outside single mounted seals, type C - double seals, type D - tandem seals, type E - gas seal, and type F - special arrangement/applications vacuum or gas seal. Grades: grade 1 - basic end face seal, grade 2 - cartridge seal, and grade 3 - split seal. Classes: class 0 - nonsplit seal assembly, class 1 - partial split seal assembly, solid gland, class 2 - partial split seal assembly, split gland, class 3 - fully split seal assembly, solid gland, and class 4 - fully split seal assembly, split gland. Seal life shall be defined in terms of the time period in which the mechanical seal functions properly under its specified service.
SCOPE
1.1 This specification covers mechanical end-face seals for centrifugal and positive displacement pumps for shipboard use.
1.2 The following types of seals are not included in this specification: lip seals, oil seals, circumferential seals, or labyrinth seals.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. A companion hard metric standard is in the process of preparation.  
1.4 Special requirements for U.S. Navy Shipboard Pump Applications are included in Supplement S1.
