Product Details

The series pumps are suitable for pumping air and other gases. The oil pump forced oil device, the inlet pressure is less than 1.33×103 when, can continuously operating advantages. It can be used alone, can also be used for the booster pump, diffusion pump, molecular pump, maintain the pump, titanium pump vacuum pump, widely used in vacuum metallurgy, vacuum coating, vacuum drying, freeze drying, vacuum degassing, vacuum packaging, vacuum, vacuum forming, food packaging, printing, sputtering, vacuum casting, photovoltaic, air fields of science and technology, chemical, electronic, refrigerator, air conditioner pipeline and laboratory vacuum operation and supporting the use of.

1, features

The preparation for the special design of town gas valve, prevent pump oil mixed with water, to extend the pump oil service time;
A, the pumping efficiency is high, the ultimate vacuum high, long service life;
B,, equipped with automatic anti-returning oil check valve, never returned to oil;
C, small diameter 2XZ-2B, 2XZ-4B, 2XZ-8B vacuum pump with vacuum drying box, freeze-drying machine, printing machinery;
D, with small caliber conversion connector, KF interface, the interface of the flange;
E, when the suction containing vapor, particle, corrosive gases, in the intake port of the pump shall be fitted with auxiliary equipment, such as condenser, dust collector.
