1HP 5L/S Oil Sealed Rotary Air Vacuum Pump

SV Oil Lubrication Single Stage Rotary Vane Vacuum Pump: 

SV oil lubricated single rotary vane vacuum pump is new style Multi-function vacuum equipment, it developed from adsorbing numerous international famous company advanced technology, take the advantages of long service design, high vacuum degree, environmental protection, complete specification etc. We own the exclusive patent.

Working Principle:


Eccentric mounting rotor rotating in the pump inside, which form centrifugal force driving vanes close to pump wall rotating, vanes divide pump body and rotor into multiple working chamber, when working chamber connect to inlet passageway, start to suction gas, vanese keep rotating and compressed gas into oil tank, oil tank inner constant differential pressure make oil enter comprssed chamber, lubricated oil and extracted gas enter into oil tank, with gravity action, exhaust filter separate lubricated oil, lubricated oil back to the bottoom of oil tank and enter into working chamber(oil recyle), oilless gas exhaust to atmosphere.

1. Long life design, the greatest value to customers.
2. Full rubber seals, improved sealing, easy disassembly.
3. Symmetrical mounting base for easy installation and transportation.
4. Vane with some self-lubricating function, can adapt to harsh process.
5. High vacuum up to 10Pa, High pumping speed also at low pressures.
6. Environmentally friendly, integrated exhaust filter, clean exhaust air. Outlet hole equip with check valve, can avoid oil back to vacuum system. Multiple vanes design, high efficiency and energy saving. Cooled air. Direct-coupled connection, low noise, low vibration, can work in horizontal plane. When ultimate vacuum reach atmospheric pressure range, can continuous running.
