Standard pump with MGE motor, complying with ISO 2858 standard

High - efficiency NKGE end - suction pumps suitable for demanding applications
The Grundfos NKGE end - suction long - coupled pump is a non - self - priming single - stage centrifugal volute pump with an axial suction port, a radial discharge port, and a horizontal shaft. When you need a pump for applications with harsh variations in flow requirements, the NKGE can be equipped with an 11 kW permanent - magnet MGE motor, an integrated variable - frequency drive, and IE5 efficiency, ensuring high efficiency at all times.
The design of the long - coupled pump, with an intermediate coupling, makes it easy to maintain. The main dimensions of the NKGE pump comply with the ISO 2858 standard. All Grundfos end - suction pumps are tested against the acceptance class standard of ISO9906:2012 before leaving the factory.

NKGE 65 - 50 - 125/105 AA1F2KESBAQEHWB
The non - self - priming single - stage volute centrifugal pump is designed in accordance with the ISO5199 standard, and its dimensions and rated performance comply with the ISO 2858 standard. The flanges are of the PN 16 type, and their dimensions conform to the EN 1092 - 1 standard. This water pump has an axial suction port, a radial discharge port, and a horizontal shaft. It adopts a back - pull - out design, enabling maintenance personnel to disassemble the coupling, bearing bracket, and impeller without loosening the motor, pump casing, and pipes. The unbalanced O - type shaft seal meets the DIN EN 12756 standard. An air - cooled, base - mounted permanent - magnet synchronous motor is installed on the water pump. The pump body and the motor are mounted on the same base frame. The motor's terminal box contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the water pump to be adjusted to the optimal operating state according to environmental conditions.
