The Grundfos NB32-200 Series is a heavy-duty close-coupled end-suction pump range designed for high head, high flow applications where reliability and performance are critical. These non-self-priming, single-stage centrifugal pumps feature an axial suction port, radial discharge port and horizontal shaft configuration, optimised to deliver exceptional efficiency with minimal flow loss.

Engineered with hydraulically and dynamically balanced impellers, the NB32-200 ensures stable, vibration-free operation at higher pressures, making it ideal for demanding industrial and commercial installations. The robust cast iron pump housing combined with durable, corrosion-resistant wear parts guarantees long service life and dependable performance when handling thin, clean or slightly contaminated liquids free from abrasive or fibrous solids.

Each NB32-200 pump is directly coupled to a powerful IEC-flanged three-phase AC motor running at 2900 RPM, providing flow rates up to 700 LPM and delivering heads up to 70 metres (700 kPa). A secure O-ring seal between the housing and cover eliminates the risk of leakage, even under high system pressures.

With its compact, close-coupled design and straightforward maintenance, the NB32-200 Series is the perfect choice for high-capacity water supply, industrial process boosting, HVAC circulation, cooling water transfer and irrigation systems where stable high head performance is essential.
