3、y all Departments and Agencies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification covers vertical or horizontal centrifugal Integral Motor Pumps (IMP) (see 6.1) for shipboard applications on U.S. Navy ships and submarines. Pumps are to be sealless and configured for either end suct
4、ion where impeller is overhung with all bearings on one side of the impeller, or in an inline configuration with the impeller positioned between two sets of bearings. The motor is an axial-field integral permanent magnet machine controlled by a variable speed drive (VSD). These characteristics are i
5、ntended to result in a pump design that has no routine maintenance requirements and weight and dimensions that are significantly smaller than the equivalent close coupled, end suction, induction motor driven centrifugal pump. 1.2 Classification. Integral motor pumps are classified using the followin
6、g ratings: 1.2.1 Pump suction and discharge flange sizes. Pump suction and discharge flange sizes are specified as follows: Pump flange size Code Pump flange size Code 0.75“ NPS 0.75 3.5“ NPS 3.5 1.0“ NPS 1 4.0“ NPS 4 1.25“ NPS 1.25 5.0“ NPS 5 1.5“ NPS 1.5 6.0“ NPS 6 2.0“ NPS 2 8.0“ NPS 8 2.5“ NPS 2
7、.5 10.0“ NPS 10 3.0“ NPS 3 12.0“ NPS 12 1.2.2 Nominal impeller diameter. Pump nominal impeller diameter in inches is rounded to the nearest whole number. 1.2.3 Maximum operating speed. Pump maximum operating speed in rpm is rounded to the nearest hundred. 1.2.4 Power rating. Motor power rating in ho
8、rsepower is rounded to the nearest whole number. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32408 2 1.2.5 Pump class. Pump application class is specified as follows: Pump class Code Freshwater C1 Saltwater/freshwater C2 Saltwater duplex
9、C3 Saltwater C4 Hydrocarbon (less than 1500 SSU) C5 1.3 Part or identifying number (PIN). PINs to be used for IMPs acquired to this specification are created as follows: (see 1.2.1 through 1.2.5) M Prefix Specification number Hyphen Discharge flange size X Suction flange size Hyphen Impeller diamete
