Factory Aligned Split-Coupled End-Suction Pump

The Grundfos NBSE split-coupled, end-suction pump with integrated permanent magnet motor, drive, and control serves as the industry standard in performance, quality, and durability. These products allow
for dynamic and intelligent solutions to many commercial building and industrial applications. With a selection of forty-one sizes available, the NBSE provides all the benefits of an NBS pump, enhanced by a
high-efficiency permanent magnet motor and variable frequency drive, manufactured by Grundfos

The Grundfos MLE permanent magnet motor with integrated variable frequency drive exceeds IE5 efficiency levels set by the International Electrotechnical Commission (IEC), currently the highest efficiency
worldwide for electrical motors. NEMA Premium Efficient motors are equivalent to IE3, meaning these MLE motors are two levels above NEMA Premium Efficiency. The combined motor and VFD efficiency is
higher than a NEMA Premium motor alone

INSTALLATION
• Seamless integration with Grundfos MLE integrated motor, drive and control for an all-in-one solution that speeds installation, startup and commissioning • Intelligent control options, including constant differential pressure and proportional differential pressure control that optimize the system based on actual demand
• Large, graphical display control interface (HMI) on MLE motor provides control of all settings, without need of separate interface device (GO Remote), and user-friendly operation • No baseplate or grouting required, reducing installation costs • No shaft alignment is required — eliminating laser alignment costs and reducing installation time
• Optimized, space-saving design has up to a 35% smaller footprint compared to traditional frame-mounted design pumps

EFFICIENCY AND RELIABILITY
• Advanced Computational Fluid Dynamics (CFD) provides reliable industry-leading efficiencies, reduce vibration, and noise providing for prolonged seal and bearing life and quiet operation
• New Silicon Carbide (SiC) / Silicon Carbide (SiC) hard faced seal’s robust design offers increased temperature range, better abrasives handling and longer life versus standard designs (standard on all
N-Series pumps)

Grundfos Lifetime Alignment Guarantee means your pump will never need an alignment,
eliminating undue wear and tear on mechanical seals and bearings. A pump that never needs
alignment will use less energy and require significantly less maintenance.

• Optimized, stainless-steel impeller design increases efficiency and reduces NPSH require

SERVICEABILITY
• Foot-mounted volute for increased pump stability • Split-coupling design allows for easy access to
mechanical seal without removing the motor or disturbing piping
