  • DESCRIPTION

    Close-coupled (NBE, NBGE) and long-coupled (NKE, NKGE) end-suction pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. Known for their sturdiness and reliability, they are ideal for use in even the most demanding applications. Application areas include water supply, industrial pressure boosting, industrial liquid transfer, HVAC and irrigation.

    NBE, NBGE, NKE, NKGE in the above mentioned power sizes are fitted with permanent-magnet motors. Medium speed motors up to 11 kW and low speed motors up to 1,1 kW have an efficiency that exceeds the IE4* demands including the energy consumption of the integrated frequency converter. Low speed motors from 1,5 kW up to 7,5 kW have an efficiency that exceeds the IE4* demands.

    NBE, NBGE, NKE, NKGE pumps are all without factory fitted sensor, no matter the power size. Via an external signal (from a sensor or a controller), the pumps allow for any configuration and control method required, i.e. constant pressure, temperature, flow or level.

    NBE, NBGE, NKE, NKGE in the above mentioned power sizes are fitted with motors with integrated frequency converters that have an efficiency that exceeds the IE3 demands. Only exemption is the 18,5 low speed motor, which exceeds the IE2 demands.
