The NASH CL liquid ring vacuum pump & compressor series delivers classic Nash performance with a broad range of suction volume, vacuum, and pressure. This single stage liquid ring vacuum pump & compressor series is available in 12 different models, with capacity ranging from 140 to 9,700 ACFM (240 to 16,500 m3/h) and can be found in many applications including paper machine dewatering, autoclaves, carburetor testing, chucking, condenser air removal, container filling, cooking, deaerating, drying, evisceration, exhausting, molding, pickup and conveying, priming, slot extraction, and solvent recovery.

Key Characteristics:

Reliable and Efficient
Engineered for Demanding Environments
ECO-FLO™ Upgrade Available

Engineered For Demanding Industrial Environments

Our CL series offers medium to large capacity, single stage vacuum pumps that are ideally matched to demanding industrial applications and harsh environments. This heavy-duty pump design accommodates a wide range of applications, typically including dewatering in the paper industry and vacuum filtering in mineral ore processing.

Reliable And Efficient With Conical Porting And Rotor Configuration

Patented in 1932, NASH’s conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. With constant innovation, NASH’s patented design features:

Option for lobe purge to minimize damage from erosion in duties with solids present
High liquid carryover tolerance
Side discharge to minimize the chance of flooded start
Performance test for all pumps

Operates As A Vacuum Pump & Compressor With A Differential Pressure Range Of 15 psig (1 bar)

Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump & compressor models can do the job with only one pump - reducing cost and simplifying installation.
