Oil Rotary Pump


The superior pumping performance of ULVAC's oil rotary vacuum pumps has earned them an excellent reputation among many users. These pumps are suitable for various applications of the vacuum deposition, the sputtering, and the food packing, etc.









ULVAC Oil Rotary Vacuum Pump - VS650A / VS750A

Oil Rotary Vacuum Pump -
VS650A / VS750A
650 to 750 m³/h (10833 to 12500 L/min)

The VS650A and VS750 are single stage oil rotary vane pumps. Design to provide low vibration and noise, the VS series eliminates the need for costly facility work. Both air cooled and water cooled models are available depending on customer installation requirements.








ULVAC Oil Rotary Vacuum Pump - VD Series

Oil Rotary Vacuum Pump -
VD Series
14.4 to 108 m³/h (240 to 1800 L/min)

Recently the move to improve work environments is creating a large demand for quieter vacuum pumps. Developed to meet this demand, the VD series are oil rotary vacuum pumps with low-noise direct-coupled motors. Designed for easy maintenance, the VD series makes daily maintenance and inspection extremely simple. Series models can be used in a wide range of applications on sites ranging from research labs (where silence is indispensable) to production lines.








ULVAC Oil Rotary Vacuum Pump - VS Series

Oil Rotary Vacuum Pump -
VS Series
150 to 288 m³/h (2500 to 4800 L/min)

VS series is a single-stage oil rotary vacuum pump coupled with a direct-drive motor. ULVAC's simplified design gives this lightweight pump the features of compact size along with low vibration operation. The substantial reduction in vibration of the VS series pump can help reduce the costs associated with having to perform special foundation work in facilities where vibration can be problematic. Additionally, enhancements in both the oil circulation and cooling systems result in increased stability of pumping performance at high inlet pressures.

These VS series pumps are typically used in a wide range of applications, especially those having a large number of repetitive pumping steps that cycle from atmospheric pressure, such as in the automated leak testing of parts, as well as numerous other industrial applications.








ULVAC Oil Rotary Vacuum Pump - PVD Series

Oil Rotary Vacuum Pump -
PVD Series
9 to 22 m³/h (155 to 372 L/min)

The PVD series are belt-driven compact rotary vacuum pumps with outstanding evacuation characteristics. They are used by a large number of ULVAC customers.








ULVAC Oil Rotary Vacuum Pump - PKS Series

Oil Rotary Vacuum Pump -
PKS Series
96 to 420 m³/h (1600 to 7000 L/min)

The PKS series models are extremely durable, large oil rotary vacuum pumps with very stable pumping characteristics. They are used in many applications, in areas ranging from the metal and automotive industries, to the chemical, pharmaceutical and food industries.








ULVAC Oil Mist Trap - TM/TMX Series

Oil Mist Trap -
TM/TMX Series

When an oil rotary pump is started at atmospheric pressure, and operated during low vacuum operation, the pump oil is exhausted along with the exhaust gas that is being pumped. This oil-laden exhaust mist, which consists of tiny oil droplets, appears as "smoke" exiting from the exhaust port of the pump.

The TM and TMX series oil mist traps help to ensure a clean working environment and protect indoor equipment from contamination that would otherwise be caused by this oil mist.
