NHB
Pumps with Channel Impeller
| Discharge Bore(mm) | 100 - 500 |
|---|---|
| Motor Output(kW) | 5.5 - 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. It is available as an extended line-up from 100 to 500mm discharge bores, 5.5 to 150kW.
