Teflon composite diaphragm: has a patented structural design, the use of finite element analysis of the fatigue resistance characteristics of the diaphragm, thus greatly extending the service life of the diaphragm, there is also no problem of oil mist pollution. Rubber surface using a special process compound PTFE coating (thickness ≤ 0.25mm), greatly improving the corrosion resistance of the pump, can resist most of the corrosive media (including strong acids, strong alkalis), compared with the traditional diaphragm, in airtightness, corrosion resistance and strength is higher than a chip.
Main features and advantages
(1) resistance to strong chemical corrosion: corrosion-resistant vacuum pump uses a special diaphragm (PTFE coating on the diaphragm surface) and pump head design, including all joints and piping, to ensure that the parts in contact with the gas are imported PTFE material, so it can resist most of the corrosive gases. The electrical switch and shell also do anti-corrosion treatment, especially for the transmission mechanism and circuit parts using corrosion-resistant materials to form a closed space, completely isolated from the outside environment, so that the vacuum pump can not only be resistant to corrosive media, but also perfectly applicable to corrosive environments, completely solve the problem of chemical corrosion resistance of vacuum pumps.
2）No pollution, maintenance-free: diaphragm vacuum pump can achieve complete solvent recovery, eliminating the pollution of the environment by toxic and harmful organic solvents and the health hazards to the operator and nearby personnel, even if the mixed solvents can be highly recycled. Diaphragm pump is a dry pump without water and oil, the user does not need to regularly clean, change the tube, change the water and other maintenance work, diaphragm vacuum pump to achieve 100% maintenance-free;.
(3) low noise, low vibration: corrosion-resistant vacuum pump using direct-drive motor power transmission, no intermediate transmission parts, coupled with the diaphragm low stroke, low noise characteristics, so the product noise can be kept below 70dB.
4）Overheating protection: Each product is equipped with a temperature protection switch, which will automatically stop when the internal temperature of the body is too high, and then start again after the temperature cools down to ensure the stability and safety of the system.
Rubber valve piece features
(1) special structural design with a special pump head to ensure sufficient flow while limiting the amplitude of vibration of the valve piece, and the vibration part of the valve piece is only subject to the pressure from the medium, which can greatly improve the service life of the valve piece.
(2) special design, so that the valve can be better sealed in one direction, even if there are condensate droplets on the valve, it can also ensure a good sealing effect.
Pump head features
Pump head material all use the new grade one polytetrafluoro (PTFE) material, with strong chemical corrosion resistance characteristics.
