Oil-sealed two-stage rotary vane pump with a nominal pumping speed of 8 L/s at 50 Hz and an ultimate pressure of 4 × 10−2 Pa with the gas ballast closed. The RV8 is intended for rough-vacuum service and backing larger high-vacuum pumps.
Description
KYKY RV8 Rotary Vane Vacuum Pump
The RV8 is a direct-drive, two-stage oil-sealed rotary vane pump for chamber evacuation and forevacuum duty. Gas ballast supports vapor handling, and the internal anti-suckback system reduces the risk of oil migration after shutdown.
