NBGE 125 - 80 - 160/161 AAF2AESBAQEPWB

The non - self - priming single - stage volute centrifugal pump is designed in accordance with the ISO 5199 standard, and its dimensions and rated performance comply with the ISO 2858 standard (16 bar). The flanges are of PN 16 type, and their dimensions conform to the EN 1092 - 2 standard. The pump is equipped with an axial suction port, a radial discharge port, a horizontal shaft, and a back - pull - out design, which allows maintenance personnel to disassemble the motor, motor base, cover, and impeller without loosening the pump casing or pipes. The unbalanced O - ring shaft seal meets the DIN EN 12756 standard. An air - cooled permanent - magnet synchronous motor is closely coupled to the pump. The junction box of the motor contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the pump to be adjusted to the optimal working state according to the environmental conditions.
