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 suction 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 intended 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.
