ASTM F Abstract This specification covers the requirements applicable to the design and construction of three classes of centrifugal pump Class 1, Class 2, and Class 3 for shipboard application. When selecting material combinations, the conditions under which the various materials interact with each other shall be taken into consideration as well as the use of nonmetallic composite pump components where the use of that material can benefit the operation and maintenance of the pump.

The requirements for the following are detailed: 1 pump design and construction, 2 pump operation at or near the best efficiency point , 3 motor power ratings, 4 pitch and roll conditions, 5 horizontal pump and driver mounting, 6 vertical pump support, 7 bedplates, 8 pump couplings, 9 guards, 10 pumps with face-mounted motors, 11 shaft alignment, and 12 indication of direction of rotation.

Pump design requirements for inlet and outlet connections, casings, radial and thrust bearings, journal and thrust bearings, rolling element bearings, mechanical seals, separate pressure boundary parts, and screw threads are specified. Requirements for paintings and coatings, equipment identification plates, and testing such as hydrostatic, mechanical run, performance, net positive suction head, vibration, and acoustic tests are also specified.
