NBG 150-125-500/548 AIAF2AESBQQEYW3
The non-self-priming single-stage volute centrifugal pump is designed in accordance with ISO 5199, and its dimensions and rated performance comply with ISO 2858 (16 bar). The flanges are of PN 16 type, with dimensions conforming to EN 1092-2. The pump is equipped with an axial suction port, a radial discharge port, a horizontal shaft, and a back-pull-out design, allowing maintenance personnel to disassemble the motor, motor bracket, cover, and impeller without loosening the pump casing or pipelines. The unbalanced O-type shaft seal meets the requirements of DIN EN 12756. An air-cooled asynchronous motor is closely coupled to the pump.
