Vacuum pump is an important filtration supporting equipment that improves filtration efficiency and enhances degassing effect. In order to ensure that the filter media is not contaminated, an oil-free diaphragm vacuum pump is generally used. The vacuum pressure of this type of pump is generally 0.08 Mpa Left and right (single level). The key to improving the filtration speed is the exhaust volume per unit time, that is, the flow index of the vacuum pump, which is particularly prominent when particles block the filter membrane when the filtration volume is large and the media viscosity is high.

        The service life of a vacuum pump depends not only on the correct usage method (such as reducing artificial continuous startup, preventing solvents from being pumped into the pump body, etc.), but also on the reasonable motor power, the design form of the vacuum film and the fatigue resistance.

Main features:

1.Provide sufficient motor power to reduce motor heating.

2.The vacuum film uses high-quality rubber with good oil resistance and fatigue resistance, and is accompanied by a reinforced textile skeleton interlayer, with a thickness of 3 mm， The service life is greatly improved.

3.HPD The series of oil-free vacuum pumps are specially designed for various vacuum equipment in the laboratory. The pressure of the double-stage pump head can be close to 0.1 Mpa， Large flow structures can also be used.  

4.High efficiency and low noise, and optional pressure regulating mode and exhaust valve configuration.
