Liquid Ring Vacuum Pump 
Large Capacity, CL

Capacity 140 to 9,700 ACFM (240 to 16,500 m3/h)

The NASH CL liquid ring vacuum pump and compressor series delivers classic Nash performance with a broad range of suction volume, vacuum, and pressure. This single stage liquid ring vacuum pump and compressor series is available in 12 different models, with capacity ranging from 140 to 9,700 ACFM (240 to 16,500 m³/hr). They can be found in many applications including electric power generation, mining and textiles, chemical processes, and general industrial applications.

Engineered for Demanding Industrial Environments

​

The CL series offers medium to large capacity, single stage vacuum pumps that are ideally matched to demanding industrial applications and harsh environments. The heavy-duty pump design is able to service a wide range of applications, which can typically include 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 chance of flooded start

  • Performance test for all pumps

 

Operates as a vacuum pump and compressor with a discharge pressure range of 36 psia (2.5 bar abs.)

​

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

NASH Classic

​

With more than 100 years of experience producing liquid ring pumps, we know how to design pumps and compressors built to last. As a result, our Classic liquid ring vacuum pumps and compressors, like the CL, are still manufactured by Gardner Denver Nash and are running in plants around the world today. Only true Classics manufactured by Gardner Nash are 100% performance tested and carry our factory warranty.
