Oil Rotary Vacuum Pumps
VS Series Oil Rotary Vacuum Pumps
(2,500 to 4,800 l/min)
 The
VS Series are oil rotary vacuum pumps with direct-coupled
motors. They use a single level of vanes (rotary vanes) to
achieve a simpler structure and faster speeds, and have compact,
lightweight and low-vibration designs. Since they greatly
reduce vibrations, the VS Series can be installed with less
preliminary work and expense (such as during plant foundation
construction). The reinforced oil circulation and cooling
water systems enable stable evacuation performance at high
intake pressures, enabling use in processes with repetitive
evacuation, and a wide range of other applications.
Features
- Low vibrations and noise
- Lightweight, compact
- Enable continuous operation at full pressure
(patent pending).
- Outstanding maintenance
Applications
- Evaporation, sputtering, ion plating
- Vacuum packaging, vacuum adhesion/conveying,
vacuum forming, vacuum casting
- Vacuum heat treatment furnaces, sintering
furnaces, brazing furnaces
- Vacuum drying, freeze-drying, vacuum deairing
- Gas substitution/supply, vacuum insulation
- Leak test equipment, other
