Key Advantages of the NC Series

✅ Strong and Durable Construction

Each pump is made with thick cast iron for long service life. For corrosive jobs, we offer optional stainless-steel construction to protect against harsh fluids.

✅ Excellent Liquid Carryover Tolerance

A single conical lobe design helps the pump handle slugs of liquid, solids, and slurries. These obstacles often reduce vacuum performance—but not with the NC Series.

✅ Wide Capacity Range

With 70 to 1700 CFM capacity options, there’s a model for nearly every job. Our team will help size your system for best results.

✅ Dual-Function Operation

The NC Series works as both a vacuum pump and compressor. It reaches up to 28” HgV vacuum and 25 psig discharge pressure. This makes it useful for many different systems.

✅ Easy Nash SC Series Replacement*

Need a drop-in replacement for a Nash Classic SC Series* pump? The NC Series offers direct part interchangeability and often improves overall performance.

✅ Two-Year Warranty

We back every unit with a 2-year warranty against manufacturer defects.
