Description
Engineering Application & Overview
The Grundfos NB, NK, NKG, and NBGE Series are EN 733 / ISO 2858-compliant horizontal, end-suction, back-pull-out centrifugal pumps engineered for the most demanding fluid transport requirements in industrial and commercial facilities. Designed on the principle of radial-flow centrifugal hydrodynamics, the double-volute casing geometry minimizes radial thrust loads at off-BEP operating points — critical for sustaining bearing and mechanical seal life across the 24/7 duty cycles typical in Batam manufacturing zones and municipal water systems. The NK and NKG variants feature a close-coupled motor flange for space-constrained installations, while the NB frame-mounted variant allows independent motor replacement. Ideal applications include: general industrial water supply and recirculation, cooling water systems for shipyard dry-dock equipment, HVAC chilled/hot water loops, pressure boosting for PT Air Batam Hulu water distribution networks, and process water transfer at Batam Industrial Park facilities.
