MVP Series Direct Drive Vacuum Pump is two-stage oil sealed rotary vane vacuum pump.
It is a new concept out of conventional design to satisfy customer's needs.
It consists of top cover, oil casing, motor housing, pump module. It occupies oil anti- suckback
valve and gas ballast for protecting pump.

Operating Principle The pump and motor are connected by flexible coupling. As the rotor rotates two vanes placed in rotor vane groove, turn making contact with the internal surface of
the cylinder due to centrifugal force.
The vacuum is achieved by induction, isolation, compression, exhaust stages.
The vacuum oil is supplied to cylinder, where rotor, vane and cylinder internal surface is in
contact and other parts for lubrication and tight sealing.

1. Excellent ultimate vacuum and pumping speed
2. Improved anti-suckback system to protect the pump in the event of sudden stop
3. International standard clamp and flange
4. Low noise level and vibration
5. Constant pressure oil circulating system
6. Convenient gas ballast valve control
7. Simple repairing and maintenance
