Product Name: MVP540 Vacuum Pump Model NO.: MVP Series Exhauster Method: Positive Displacement Pump Structure: Rotary Vacuum Pump Origin: Korea Product Description 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.TECHNICAL DATAUNITMVP540Displacement Speed50HzL/s12560Hz150Ultimate PressureWith Gas BallastTorr5×10 -3Without Gas Ballast5×10 -4Inlet PortmmISO 100Outlet PortmmISO 100Motor PowerkW15Rotational Speed of Pump50HzR.P.M145060Hz1750Oil FillingL35Weightkg668
