Oil rotary vane vacuum pump

This vacuum pump boasts excellent durability due to simple design equipped with a single axis and direct driving method , along with low maintenance and operational costs. Its operation principle is as follows: When the rotor mounted on the inside of the cylinder with eccentricity and vane inside the rotor make a turn, the vane rotates along the side wall of the cylinder by centrifugal force, when the gas inhaled in the state sealed by oil supply is compressed and discharged through the exhaust filter. Oil has a recycled structure, while implementing sealing and lubrication. The separation oil circulation system in a exhaust part facilitates its use even in situation in which a large amount of oil vapor occurs at a low vacuum state. The optional cooling device can be applied in accordance with temperature conditions around the installed pump or suction processes and used to improve operational stability of the pump and oil. In addition, the integrated backflow prevention values and efficient oil filter devices make it possible to conduct suitable configuration using various accessories. Integrated lubricating oil cooler and standardized circulation-type lubrication system minimizes noise generation.
