Key Benefits of the NHF Series

Compact Design

The NHF Series fits where other pumps can’t. Its small footprint allows easy installation and minimizes space requirements.

High Efficiency

These pumps offer up to 40% more CFM output per horsepower input, helping reduce operational energy costs without sacrificing performance.

Flood-Resistant Porting

Inlet and outlet ports sit below the shaft height, creating a self-draining system that prevents flooding. The built-in anti-cavitation port further protects the pump and extends its lifespan.

Robust and Reliable

Even in the presence of harsh gases, chemical vapors, and contaminated steam, the NHF Series keeps running. It’s trusted across industries for durability and consistent performance.


Distributed Nationwide. Proven in the Field.

The NHF Series is in operation across the U.S., performing in demanding environments where others fail. Whether you’re sterilizing medical equipment or processing food waste, this pump stands the test of time.
