Vacuum Pumping System

YMV Series



YMV series is a frame unit for combining a mechanical booster pump and an oil rotary vacuum pump.
We prepared four types of frame units according to the pumping capacity.
The independent frame design emphasizes on the maintainability of pumps. This product is ideal for use in production facilities.
Note: Mechanical booster pump and oil rotary vacuum pump need to be purchased separately.

Remarks YMV series is the frame unit for mechanical booster pumps. Purchase a mechanical booster pump and a oil rotary pump separately. Refer to the brochure about the specification of mechanical booster pumps and oil rotary pumps. Options for individual pump are available. (Select the inverter for atmospheric pressure start operation from options for YMV series).
*1 The frame unit contains the frame, connection pipes, bellows and casters with adjusters.
*2 Combination with recommended pumps.
*3 Ultimate pressure is measured by Pirani vacuum gauge.
*4 Water cooled operation is required depending on intake pressure. Refer to the brochure of the mechanical booster pump for details.
*5 Select the inverter from I2 or I4. I2 is for 200 to 240V and I4 is for 380V to 480V.
*6 Select the control box from AC200V, AC220V, AC380V, AC400V, AC415V, AC440V, AC460V or AC480V.
*7 The suction flange includes dia. 18m gauge port, leak port and 1/4B socket.
*8 1/4B socket is necessary to connect the delay vacuum solenoid valve. Optional suction flange is recommended.
*9 DC24V cooling water flow switch.
