Diffusion pump for the high vacuum

Detail

application ： high vacuum

K/KT series -High vacuum oil diffusion pump

Series KT/K are the equipment mainly used for getting the high vacuum condition; we adopt this equipment, valves, water cooling baffle, pipe and mechanical vacuum pump as the high vacuum unit. 10-2～10-5Vacuum degree of work can be achieved. If liquid nitrogen or other cooling device can be used, it can get ultra-high vacuum (10-6kpa) with baking.
The pumping capacity is big, the pumping speed can be changed range from 480L/S to 13000L/S, it adds observation windows, oil inlet and outlet and pump oil temperature measuring device, KT2 adopts stretching process, reduces weld crack and out gassing and increases strength. There are two kinds of heater you can choose: heating wire or heating plate,
It is widely used in vacuum coating, vacuum furnace, electron, chemical industry, aviation, metallurgy, aerospace, materials, biomedicine, atomic energy and universe probe hi-tech field
