Oil-sealed two-stage rotary vane pump with a nominal pumping speed of 18 L/s at 50 Hz and an ultimate pressure of 4 × 10−2 Pa with the gas ballast closed. The three-phase RV18 provides DN40KF connections for industrial forevacuum service.
Description
KYKY RV18 Rotary Vane Vacuum Pump
The RV18 is a direct-drive, two-stage oil-sealed rotary vane pump designed for higher-throughput rough-vacuum and backing service. Internal oil circulation, gas ballast and anti-suckback protection support sustained operation within the manufacturer limits.
