1. High corrosion resistance
Chemker410 and Chemker411 corrosion-resistant vacuum pump uses PTFE material in the part in contact with gas, which can withstand most corrosive gases. At the same time, the electrical switches and casing are also treated with corrosion protection, which is suitable for pumping various organic, acid-base and other corrosive gases.
2. No pollution and maintenance-free
Chemker410 and Chemker411 corrosion-resistant vacuum pump uses the principle of diaphragm action (Diaphragm), and does not need to use oil for lubrication, so there is no need for regular oil maintenance and no oil mist pollution.
3. Quiet, low vibration
Chemker410 and Chemker411 corrosion-resistant vacuum pump adopts direct-drive power transmission, coupled with the low-stroke and low-noise characteristics of the diaphragm, so that the noise of this series of products can be kept below 50dB, quiet and low-vibration are among the best in the same class.
4. Overheating protection device
Chemker410 and Chemker411 corrosion-resistant 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.
