This specification covers the design and construction requirements of rotary positive displacement distillate fuel pumps intended for use in shipboard. Pumps covered by this specification are of Types II, III, IV, V, VIII, X, and XI and of sizes A-H. The pump shall be manufactured capable of sustaining operation in any direction up to a certain inclination, shall withstand environmental vibration induced by shipboard machinery and equipment, shall be driven by an electric motor, and besides distillate fuel, the pump shall also be used to pump aviation turbine fuel. Performance acceptance tests shall be performed, including mechanical running test, noise test, and hydrostatic test, and shall conform to the requirements specified.

1.1 This specification covers the requirements applicable to the design and construction of rotary positive displacement distillate fuel pumps for shipboard use.

1.2 Lineal dimensions and units of force in this specification are expressed in inches and pounds respectively. A companion metric standard is in the process of preparation.
