The NHU pumps are centrifugal, single-stage, volute pumps.
Hydraulic part consists of volute casing, there is a closed impeller with single-sided water inlet, with front and back wearing ring and with relieving holes.
Mechanical part consists of bearing pedestal, where is placed shaft in two radial bearings. Bearings are lubricated with oil. Design of the NHU pump enables the pump disassembly starting from the pump drive (electric motor) side, without disassembly of suction and discharge pipeline. The sense of the pump shaft rotation is clockwise facing the pump from the side of drive.
The standard execution of the pump is the execution with the soft packing - flooded, closed, flushed,
