VVN Liquid ring vacuum pumps
JSC Vacuummash produces liquid ring vacuum pumps as for general industrial use and also for hazardous production facilities.
3 VVN pumps produced according to specifications 3648-053-00218526-2013 are used in general purpose industrial use.
2 VVN pumps produced according to specifications 3648-015-00218526-2000 are used in hazardous production facilities. Such pumps are produced by conducting NDT procedure.
Liquid ring pumps with capacity from 0,3 to 50 m3/min are designed for pumping vapor and gases in order to create vacuum in the range of operating pressures from atmospheric to 10 kPa in technological process.
VVN pumps are used in all industries where is needed to pump dirty covered by dust gases containing condensed moisture and also burning, highly explosive, corrosive gases. These pumps create rough vacuum in wide range of capacity or used in combination with water-steam ejector vacuum pumps and roots blowers. Lack of parts in rubbing contact, wide gas passages and small quantity of component parts allows these pumps to operate without repair for many years.
