An oil sealed rotary high vacuum pump is a type of vacuum pump that uses rotating blades or vanes to create a vacuum by drawing gas molecules from a chamber or system. The pump is sealed with oil, which provides lubrication and also serves as a barrier to prevent gas from leaking back into the system.

JD VACUUM SERVICE - oil seal vacuum pump

single stage rotary vane vacuum pumps are commonly used in a variety of applications that require high levels of vacuum, such as in research laboratories, semiconductor manufacturing, and vacuum coating processes. They can achieve high vacuum levels of up to 10^-6 Torr or even lower.

These pumps operate by using a rotor with vanes that rotate within a stator, creating a series of expanding and contracting chambers. As the rotor turns, gas molecules are drawn into the chambers and compressed before being discharged through an exhaust port. The oil seal around the rotor prevents gas from escaping back into the chamber.

Maintenance is important for oil seal rotary high vacuum pumps, as the oil can become contaminated with gas ballast and other impurities. The oil needs to be changed periodically, and the pump should be cleaned and inspected regularly to ensure optimal performance.

oil seal rotary high vacuum pump for laboratory

Oil seal rotary high vacuum pumps are commonly used in laboratory settings for a variety of applications that require high levels of vacuum, such as in chemical and materials research, physics experiments, and other scientific applications.

In laboratories, oil seal rotary high vacuum pumps are used to create and maintain a high vacuum environment, which is important for a wide range of research and analytical techniques. Some of the specific applications of these pumps in laboratories include:

  • Mass spectrometry: Mass spectrometers require a high vacuum environment to operate, and oil seal rotary high vacuum pumps are often used to create and maintain this vacuum.
  • Electron microscopy: Electron microscopes use high vacuum environments to avoid interference from air molecules, and oil seal rotary high vacuum pumps can be used to create and maintain this vacuum.
  • Thin film deposition: Many thin film deposition techniques, such as physical vapor deposition, require a high vacuum environment to create high-quality films. Oil seal rotary high vacuum pumps are often used in these applications to create and maintain the necessary vacuum.
  • Chemical and materials research: In chemistry and materials science, oil seal rotary high vacuum pumps are used in a variety of applications, such as to create a vacuum for distillation or to maintain a vacuum during reactions.

Overall, oil seal rotary high vacuum pumps are an essential tool in many laboratory settings and are widely used in scientific research and experimentation.

Oil Sealed Rotary High Vacuum Pump best price India

Owing to competitive prices, planet-class quality, standards, and long operational life, our Oil sealed rotary high vacuum pump (laboratory Models) becomes the foremost preferable choice of consumers.

Rotary pump

High Vacuum Pumps are available in Single & Double stages directly coupled to the motor flange or with V-Belt driven. Directly coupled to a motor flange the pumps are compact in size, and evenly balanced with an exceptional size-to-performance ratio. V-Belt-driven pumps are supplied with an air or water-cooled jacket. Available in various capacities.


Our oil seal vacuum pumps are oil-immersed, rotary vane-type pumps. The rotor, with two spring-loaded vanes, is mounted eccentrically within the stator body. because the rotor, rotates the vanes sweep the crescent shapes, and air space twice in each revolution. there’s an in-built non-return valve that prevents backflow parts from being precisely machined, ground, and assembled with close tolerances.

With our specially designed pumps, maximum vacuum is often achieved during a very short period. Thus, the increase in the temperature of the unit is successfully checked and therefore the wear and tear of its components also are reduced. Hence, our oil seal air pump has emerged as an extended-lasting, noiseless, and trouble-free performer for years.
