Frequently asked questions

The Rezitech CNN/CNP Series is a proven direct replacement solution for many existing Nash CL liquid ring vacuum pumps, including models from the CL1001 through to CL14003G series. Designed for bolt-in compatibility, the CNN/CNP Series helps minimise downtime and reduce the need for costly installation or piping modifications during pump replacement projects.
Featuring a robust conical liquid ring vacuum pump design, low vibration operation, and factory-tested performance, the Rezitech CNN/CNP Series provides a reliable and efficient upgrade for ageing industrial vacuum systems operating in demanding environments.
These replacement liquid ring vacuum pumps are widely used across pulp & paper mills, sugar processing plants, mining operations, chemical processing facilities, and power generation sites where continuous-duty reliability and long service life are essential.
Rezitech can also assist with selecting the correct replacement pump based on your required vacuum level, flow rate, motor configuration, seal water system, and existing baseplate or pipework arrangement.

CNN/CNP Series pumps are commonly used in mining, pulp & paper, sugar processing, power generation, coal handling, and other heavy industrial applications. They are ideal for evacuating gases, vapours, and entrained liquids in demanding continuous-duty environments.

CNN/CNP Series Liquid Ring Vacuum Pumps are specifically suited to mining environments because they can reliably handle wet, dirty, and dust-laden gases common in coal handling and mineral processing operations. Their robust construction and continuous-duty design make them ideal for harsh mining conditions where reliability and uptime are critical.
