This series of pumps is used as the basic equipment for the extraction of gases from sealed containers. It can be used alone, but also can be used for booster pumps, diffusion pumps, molecular pumps, pre-pump pumps, maintenance pumps, titanium pumps, vacuum drying, freeze drying, vacuum degassing, vacuum packaging, vacuum adsorption, vacuum forming, coating, food packaging, printing, sputtering, vacuum casting, instrumentation, instrumentation, refrigerators, air conditioning lines, laboratories and other vacuum operations.
◇ Effective low-noise design and precision machining, low noise
◇ The air inlet is equipped with a negative pressure gauge, the number is intuitive, and the operation is simple
◇ Special design gas ballast valve to prevent pump oil from mixing with water
◇ Adopt international similar product design, small size, light weight, low noise, easy to start
◇ It is equipped with an automatic double anti-oil return safety device, which will not return oil
◇ It can be equipped with small-diameter adapter joint, KF interface and flange interface
