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.
