4 NOMENCLATURE AND DEFINITIONS
4.1 Definitions of Terms
All nomenclature and definitions of pump components shall be in accordance with ANSI/HI 5.1 through ANSI/HI 5.6.
canned motor pump (CMP): a type of scalless pump where the impeller is mounted on the end of the shaft that is overhung from its motor bearing supports. The impeller is mounted directly on the rotor assembly, making one rotor assembly. The bearings are supported by housings at each end of the rotor assembly. The motor components are protected from the process liquid by corrosion resistant, nonmagnetic liners (shells). During operation, the motor section and bearings are either cooled and lubricated by the process liquid or a flush introduced from an external source.
close coupled magnetic drive pump: a sealless magnetic drive pump as defined below except the outer magnet ring is mounted on the driver shaft.
magnetic drive pump (MDP): a type of sealless pump where the impeller is mounted on a rotor assembly that contains the inner magnet ring of a magnetic drive. The process fluid is retained by a corrosion resistant containment shell that separates the inner magnet ring and the outer magnet ring. The outer magnet ring is mounted on the shaft of a frame that is coupled to a motor or power device.
plastic lined sealless pump: a type of sealless magnetic drive pump which consists of a metal outer casing covered internally by a plastic lining for chemical resistance. The metal outer casing gives structural rigidity for pressure containment and externally applied nozzle loads. The containment shell may consist of a reinforced outer shell with a plastic insert for chemical resistance, an engineered ceramic or other nonmetallic construction. All nonpressure-containing wetted parts are either covered by a plastic lining or may be made of an engineered ceramic.
separafeli coupled magnetic drive pump: a sealless magnetic drive pump as defined above where the outer magnet ring is mounted on the shaft of a frame that is separately coupled to a motor or power device and mounted on a common baseplate.
4.2 Additional Definitions
auxiliary piping: includes all piping connected to the pump excluding the main piping connected at the pump suction and discharge flanges. Auxiliary piping includes piping, tubing, and all attached components such as valves, instrumentation, and coolers.
