NHB
Pumps with Channel Impeller
| Discharge Bore(mm) | 50 - 500 |
|---|---|
| Motor Output(kW) | 0.75 - 150 |
The NHB-series is a submersible channel impeller pump designed for handling raw sewage, wastewater and heavy-duty industrial applications, where the pump is subject to complete submersion and requires maximum reliability. A shrouded channel impeller practically prevents internal clogging and enables the pump to efficiently transfer sewage and wastewater containing solid matters.
