Alcatel 2033SD

This used Alcatel 2033SD is a higher-capacity two-stage rotary vane vacuum pump from the long-running SD series, built to deliver stronger pumping speed for larger vacuum chambers and more demanding laboratory or industrial processes. It is frequently used as a backing pump for diffusion pumps and turbomolecular pumps, as well as a standalone vacuum source for applications like vacuum impregnation, degassing, and freeze drying where higher throughput is required. The 2033SD's oil-sealed dual-stage mechanism is designed for continuous duty and dependable ultimate vacuum performance. Facilities that rely on the SD series appreciate its rugged mechanical simplicity, which translates into straightforward servicing and a long operational lifespan when properly maintained. The 2033SD in particular has been a common choice where more volume needs to be evacuated quickly, and its widespread use over the years means parts and service expertise remain easy to find, helping labs avoid unnecessary downtime. This unit is offered as used equipment removed from a working vacuum setup, making it a sensible option for buyers who need a capable mid-to-large rotary vane pump without paying for new. Buyers are encouraged to perform an oil change and a vacuum performance check upon receipt to confirm the pump is ready for its next installation.
