Standard Specification for Rotary Positive Displacement Pumps, Ships Use

ABSTRACT
This specification defines the requirements for rotary positive displacement pumps for shipboard use. This specification does not include pumps for hydraulic service or cargo unloading applications. Pumps under this specification include the following types and classes: Type II, Type III, Type IV, Type V, Type VIII, Type X, Type XI, Class A, Class B, Class CD, Class CH, Class DD, Class DH, Class G, Class LM, Class LA, Class M, and Class W. Pump component parts such as casings, heads, and covers; shafts; rotors; rotor housings, liners, and disks; glands; bedplates and brackets; timing gears; fasteners (studs, bolts, screws, and nuts); O-rings and other elastomers; gaskets; and vanes and shoes, shall be constructed of the specified materials. General requirements for: (1) service life, (2) operation during inclinations, (3) environmental vibration, (4) internally excited vibration levels, (5) airborne noise level, (6) driver, (7) reduction gears, (8) mounting of horizontal and vertical pumps, (9) seating surface, (10) face mounted motors, (11) couplings, (12) direction of rotation, and (13) inlet and outlet connections, are detailed. Pump design and construction requirements for the following are specified: (1) flanges, (2) pump casing, (3) radial and thrust bearings, (4) rolling contact bearings, (5) mechanical shaft seals, (6) backup packing box, (7) pump head or end covers, (8) rotors and timing gears, and (9) fasteners. The pump shall meet the required rated capacity. Requirements for (1) painting and coating and (2) testing including hydrostatic test, mechanical running test, and performance test are also specified.
SCOPE
1.1 This specification defines the requirements applicable to design and construction of rotary positive displacement pumps for shipboard use. The classes of service are shown in Section 4.  
1.2 This specification will not include pumps for hydraulic service or cargo unloading applications.  
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.
