: Principle and Application of Corrosion Resistant Diaphragm Vacuum Pump

Laboratory vacuum pump users often encounter problems such as short life and high failure rate when pumping corrosive gases during operation. This is because many vacuum pumps are designed with different internal structures and materials. They are non-corrosive. 3EmTextile Testing Instruments, Testing Equipment Manufacturer


In particular, customers such as vacuum drying ovens, rotary evaporators, centrifugal concentration, vacuum distillation, etc. have extremely high requirements for chemical corrosion resistance. 3EmTextile Testing Instruments, Testing Equipment Manufacturer


The anti-corrosion diaphragm oil-free vacuum pump is designed for such customers, and its material and structure are quite different from the product vacuum pump. 3EmTextile Testing Instruments, Testing Equipment Manufacturer


First of all, all parts that come into contact with the gas are made of PTFE polytetrafluoroethylene, which is molded in one go using a mould. materials like glass. 3EmTextile Testing Instruments, Testing Equipment Manufacturer


Secondly, the interior features an oil-free design that can be used even when plugged incan be detected and no pump oil has to be refilled. The traditional oil pump is easily corroded by the pump oil. After the pump oil is corroded, it slowly corrodes. The internal parts of the machine cause the breakdown of the entire machine. 3EmTextile Testing Instruments, Testing Equipment Manufacturer


Thirdly, this type of diaphragm construction pump has excellent sealing performance, which ensures no corrosive gas leaks into the air and better protects the safety of operators. 3EmTextile Testing Instruments, Testing Equipment Manufacturer


Due to the above construction, the diaphragm pump is suitable for the following purposes:3EmTextile Testing Instruments, Testing Equipment Manufacturer


a. Small Vacuum Drying Oven:3EmTextile Testing Instruments, Testing Equipment Manufacturer


Suitable for small volume vacuum drying ovens of 20 liters and less. The corrosive gas generated during the drying process can be sucked directly into the pump without pre-treatment, and the pump itself does not need to replace the pump oil, which makes the operation easier;3EmTextile Testing Instruments, Testing Equipment Manufacturer


2. Rotary Evaporator:


He can do with rotationns evaporators from any manufacturer and avoids the disadvantages of traditional circulating water pumps, which are not particularly resistant to corrosion and which are still after years of use. Durable;3EmTextile Testing Instruments, Testing Equipment Manufacturer


3. Matching various corrosive gas pumping equipment: Can be used as a vacuum source for various equipment, clean and pollution-free, low noise, and can achieve high vacuum. 3EmTextile Testing Instruments, Testing Equipment Manufacturer
