1. High corrosion resistance.
Chemker series vacuum pump uses PTFE material in the part in contact with the gas, which can resist most corrosive gases. At the same time, the electrical switch and housing are also treated with anti-corrosion treatment, which is suitable for pumping various organic, acid-base and other corrosive gases.
2. No pollution and maintenance free.
Chemker series vacuum pumps use the diaphragm actuation principle and do not need oil to lubricate, so there is no need for regular oil maintenance and no oil mist pollution.
3. Quiet, low vibration.
Chemker 300 vacuum pump adopts direct drive power transmission, coupled with the characteristics of low stroke and low noise of the diaphragm, so that the noise of this series of products can be kept below 52dB, and the quietness and low vibration are among the best in the same class of products.
4. Overheat protection device.
Each model of Chemker series vacuum pump is equipped with a temperature protection switch inside the motor. When the internal temperature of the body is too high, it will automatically stop and wait for the temperature to cool down before starting automatically.
