Optics technology is the manufacturer of vacuum pump. Optics technology is iso 9001:2000 certified company. Vacuum pump is immersed in oil and its shaft seal is designed in such a way that it totally eliminates possibility of suction of air through it. It is designed to achieve maximum vacuum in a very short time. The vacuum pump successfully checks the rise in temperature of the unit. It reduces the water and tears of its components and makes it suitable for noiseless and trouble free performance\ for years and helps in reduction of repair bills. The main assembly of the vacuum pump consists of a stator with a rotary mounted eccentrically. The rotor is fitted with two spring loaded diametrically opposed vanes, which move in and out of their slots, pressing against the inner surface of the stator. Vacuum pump can be carried out easily without removing the main housing from its base plate and disturbing the alignment.
