This pump is highly suitable for various demanding application scenarios and can provide reliable and effective water supply.Due to the use of a tightly coupled pump design, installation in a limited space is very simple. The main dimensions of the NBG end suction centrifugal pump comply with the ISO2858 standard and are tested according to the ISO909906:2012 acceptance level standard before leaving the factory. NBG 300-250-500/525 AIAF2AESBAQEWW5The non self-priming single-stage vortex shell centrifugal pump is designed according to the ISO5199 standard, and its size and rated performance comply with the ISO2858 standard (16 bar). The flange is PN 16 type, and its dimensions comply with EN 1092-2 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.
