Siemens 2BV Series Replacements: NES NCC Series – Single Stage, Port Plate, Liquid Ring Vacuum Pumps
Our cast iron close-coupled vacuum pumps are the economical choice for small single stage close-coupled liquid ring vacuum pumps. Designed as drop-in replacements for Siemens 2BV series, the NCC series models are also comparable to the Tuthill A series and Dekker DV B-K series. Standard construction is cast iron with Stainless Steel 304 impeller and Viton elastomer mechanical seal. The NCC Series units come with a one-year warranty against manufacturer’s defects.
Please note, this warranty does not cover damage of:
- motor burning due to improper electrical connections in the terminal box.
- cavitation due to improper feeding of seal fluid to the pump.
For questions or concerns, feel free to contact an NES representative. Alternatively, the manual is available for download and contains relevant information on proper operation and maintenance. This includes the relevant electrical diagrams and cavitation protection port.
