Grundfos End-Suction Pumps are all single-stage, centrifugal volute pumps with axial suction port, radial discharge port, and horizontal shaft. Our Grundfos range is powered by a choice of two pumps: the NB Series and NK Series.

Both ranges comply with EN733 standards and are available in several shaft seal and material variants. The NB range is a close-coupled pump, allowing for easy servicing with the possibility of spacer coupling. The NK range is long-coupled and allows for the use of standard motors or special requirements.
