Conical Lobe Single Stage Liquid Ring Vacuum Pumps and Compressors – Large Capacity
The NL Series is a line of timeless drop-in replacements for the Nash classic dual cone liquid ring CL Series 1, 2, and 3 models with direct part interchangeability for every sub-series listed below. The series goes up to 15,000 CFM for large capacity applications, but goes as low as 300 CFM, making for a vast array of different pumping speeds and required horsepower to balance out for an optimized vacuum system requiring rough vacuum levels from 5” to 28” Hg vac.

The NL Series is available in cast iron/Teflon packing standard construction material with optional bronze, stainless steel 316, or stainless steel 304 construction, mechanical seals with Viton elastomer, and spare parts and repair kits. The NL Series models come with a 2-year warranty against manufacturer’s defects.

This series is tried and true to have stood the test of time for Autoclaves, Evisceration, Evaporating, Cooking, Dewatering, Slot Extraction, Labeling and Forming in the Food, Chemical, Paper and Pulp, Medical, Textiles, Beverage, and pharmaceutical industries.

The NL Series Vacuum Pumps offer:  

Robust Construction: The NL Series are large in size, with thick cast iron chambers that are designed to last decades in the most wet and dirty environments.  

Dual Function Compatibility: The 01 models of the NL Series are able to perform both vacuum pumping up to 28” Hg vac. and compression up to 14.7 psia while the 02 and 03 models are solely vacuum pumps reaching 28” Hg vac., allowing for an even wider selection. It is based on the needs of any system.  

Flooding Resistance: The dual conical lobe configuration combined with the size of the NL Series allows for high liquid carryover tolerance with capabilities for anti-flooding, greatly extending the life of the pump.
