NBE/NBGE pumps are close-coupled pumps equipped with a motor with built-in frequency converter
Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications demanding reliable and cost-efficient supply. End-suction pumps are used in five main fields of applications: Water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.
NBE/NBGE pumps are close-coupled pumps equipped with a motor with built-in frequency converter and the necessary application software to achieve an all-in-one solution enabling electronic speed control. Electronic speed control enables continuously variable control of motor speed which again enables adaptation of the performance to a given requirement.
The NBE pump lives up to the EN733 standard and the NBGE pumps lives up to the ISO2858 standard. The range for motors with built-in frequency converter goes up to 22 kW.
In comparison with NKE/NKGE pumps, NBE/NBGE pumps are more compact and therefore fit into confined spaces. On the other hand NKE/NKGE end-suction pumps are easier to service because of the spacer coupling.
