Oil backflow prevention & low vibration/low noise! With the adoption of a pressurized oil supply system, operation from atmospheric pressure to high vacuum is smooth.
The "Small Rotary Pump" is a product that operates smoothly from atmospheric pressure to high vacuum using a pressurized oil supply method. In particular, the RV series is designed to achieve smooth continuous operation not only at high vacuum but also at high throughput (high pressure), incorporating an oil flow adjustment valve. It completely prevents oil backflow during sudden stops, such as power outages, keeping the system in a vacuum state. Additionally, due to precision machining and a special oil supply method, it has extremely low vibration and noise, with the RV series operating at around 48 dB(A). 【Features】 ■ Smooth operation from atmospheric pressure to high vacuum using a pressurized oil supply method ■ Oil backflow prevention mechanism ■ Low vibration and low noise ■ Complete prevention of oil backflow during sudden power outages *For more details, please refer to the PDF document or feel free to contact us.
