SciencetoolCH301/CH300/CH400/CH600 corrosion-resistant diaphragm vacuum pump
Product Introduction
CH400 Chemical Corrosion Resistant Diaphragm Vacuum PumpAdopting a PTFE oil-free diaphragm structure, the dry trial operation only requires plugging in to work, while significantly improving the equipment's chemical corrosion resistance. It can work continuously for 24 hours without interruption, and is not afraid of corrosive gases, making it more widely applicable and compatible with various equipment and instruments.
Product Application
The corrosion-resistant oil-free diaphragm vacuum pump CH400 is suitable for vacuum filtration and purification of organic solvents or highly corrosive liquids, vacuum drying, electrophoresis transfer, solid-phase extraction, and other corrosive gases.
Product Features:
1. Take into account resistance to chemical corrosionCorrosion ability and suctionThe new generation oil-free diaphragm vacuum pump product with high suction speed can reach 33L/min, and the high suction efficiency makes this model more widely applicable.
2. A true oil-free diaphragm structure that only requires plugging in a power source to function, without the need for any auxiliary media such as pump oil or water. *Dry operation ensures that the use process does not cause environmental pollution and does not require maintenance such as oil change in the future.
3.Adopting a dual cylinder combination and coupled structure, during operation, the two sets of cylinders work together to simultaneously suction gas, which can significantly improve suction efficiency and accelerate suction speed compared to similar products.
4. From the inlet to the outlet of the vacuum pump, all components in contact with the gas are made of PTFE polytetrafluoroethylene material, including the cylinder body, diaphragm, and even small parts such as inlet and outlet valve plates and pump pipe interfaces, all of which are made of PTFE as raw materials by mold casting. Compared with traditional PTFE coated products, it solves the problems of easy wear and consumption of coatings and non corrosion resistance of detailed components, and has excellent chemical corrosion resistance.
5. The surface of the casing is treated with anti-corrosion paint, and the power switch is equipped with a splash proof protective cover as standard. The corrosion-resistant design is applied to the details of the pump, making it safer and more durable.
6. Optional vacuum regulating valve made of corrosion-resistant materials and processes, with multiple functions such as displaying and observing vacuum degree, adjusting vacuum degree and pumping speed, and preventing liquid backflow.
