NB 65-200/205 AAF2KESBQQEJW3
The non self-priming single-stage vortex shell centrifugal pump is designed according to the ISO5199 standard, and its dimensions and rated performance comply with the EN 733 standard (10 bar). The flange is PN 16 type, and its dimensions comply with EN 1092-1 standard. The water pump is equipped with an axial suction port, a radial discharge port, a horizontal shaft, and a rear pull design, which allows maintenance personnel to disassemble the motor, motor seat, cover, and impeller without loosening the pump casing or pipeline. The unbalanced O-type shaft seal complies with DIN EN 12756 standard. A air-cooled asynchronous motor is tightly coupled to the water pump.
