Manufacturer of vacuum pumps DVN-5000
In 2007 our company (we were the main sub-contractor)by the order of JSC "Corporation VSMPO-AVISMA" has been designed and manufactured twin-rotor vacuum pump DVN-5000, which was to replace the obsolete pumps ARPW-15000A.Pump of similar performance commercially anywhere in the world is produced. The pump is designed in CAD COMPASS 3D-design.
Below are given the characteristics of the pump DVN-5000 compared to the model analog (ARPw-15000A).
