Standard pump compliant with EN 733

Customizable NK end - suction pumps for demanding applications.
The Grundfos NK 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. If you need a versatile pump suitable for a variety of demanding applications, the NK/NKG ensures reliable and efficient supply.

Thanks to the use of a spacer coupling, the long - coupled pump is designed for easy maintenance. The main dimensions of the NK pump comply with the EN733 standard. All Grundfos end - suction pumps are tested according to the acceptance grade standard of ISO 9906:2012 before leaving the factory.

NK 350 - 350/416 - 382 AA1F1SBESBQQEYW3
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 EN 733 standard. The flanges are of PN 10 type, and their dimensions conform to the EN 1092 - 2 standard. The 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 - ring shaft seal meets the DIN EN 12756 standard. An air - cooled, base - mounted asynchronous motor is installed on the pump. The pump body and the motor are mounted on the same base frame.
