The Grundfos NK and NB series are heavy-duty horizontal end suction centrifugal pumps built for medium-to-large scale installations. Designed for HVAC, district heating and cooling, water supply, irrigation, and industrial process applications, these pumps deliver consistent, efficient performance. Their robust cast iron construction and standardized dimensions simplify maintenance and replacement.
The long-coupled NK allows motor swaps without disturbing pipework — perfect for critical systems — while the close-coupled NB offers a compact footprint ideal for space-constrained plant rooms.
