MVP Series 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 and vacuum system.
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 inhaled gas is trapped
between two vanes as the rotating vane passes through the inlet
passage and this trapped gas is compressed as it rotates toward
exhaust valve and eventually through valve. The vacuum oil is
supplied to the moving parts for lubrication and tight sealing.
