NHU
Pumps with Vortex Impeller
| Discharge Bore(mm) | 50 ･ 80 |
|---|---|
| Motor Output(kW) | 0.75 - 3.7 |
The NHU-series is a heavy-duty submersible pump equipped with a vortex impeller for pumping sewage and wastewater. The semi-vortex design provides a solids passage that is 70% or more* of the discharge bore, thus reducing troubles caused by the clogging of fibrous solids to a minimum. Rotation of the impeller produces vortex flow in the pump casing, which allows those foreign matters to be pumped out with minimum contact to the impeller.
* excluding model 80NHU21.5
