Description
KT Series Water Cooled Oil Diffusion Pump
KT series oil diffusion pump is the main equipment for obtaining high vacuum(10-1-10-5Pa) with high pumping speed from 1750 L/s to 130000 L/s.
KT Series Pump Advantage:
1)The pump equipped with observation window, oil filling and discharge port, pump oil temperature control and over heated protection device, and cooling water high temperature alarming device.
2)The heater of diffusion pump is composed by several heating rods, parallelly connected, which allow the rod being changed with pump running and help to shorten the heating time and increase heating efficiency.
3)Low oil return. Without water cooling plate, the oil return is 1×10-3 mg/cm2·min for normal diffusion pump oil, and 1×10-4 mg/cm2·min for 275 silicone oil.
4)The manufacturing process takes stretching technology which helps to lessen weld joint, increase intensity, and lower the air leakage.
Application:
This pump is widely used in vacuum coating, vacuum furnace, electronics, chemical industry, aviation, aerospace, metallurgy, material, biological medicine, atomic energy, space exploration and other high-tech fields, also it possesses high praise in titanium sponge field.
