The slightest defect in the PCB industry can be costly. The PCB industry typically uses processes such as etching, stripping, cleaning, and surface preparation from the PCB industry. The media often uses acid or alkali fluids with strong corrosive properties, and manufacturers need systems that can meet stringent standards. The reliability of chemically resistant pumps makes them ideal for these processes, and circuit board and electronics manufacturers can rely on chemically resistant pumps to complete the process in filtration, etching and rinsing applications.
In the etching process, strong acid is commonly used as the chemical solution. Strong acid is a corrosive liquid, part of which also has a strong irritating odor and is extremely volatile. Although it is not flammable, but can react with most metals, so that metal damage, touching the skin is easy to cause burns. So, in the chemical pump selection is recommended to use QEEHUA’s modified plastic centrifugal pump, modified plastic magnetic pump is more suitable, plastic magnetic pump in the impeller, pump cover, are made of plastic raw materials injection molding as a whole, receiving the liquid part of the pump body material are used FRPP or PVDF and CFRETFE processing.
PCB circuit board cleaning, pharmaceutical liquid circulation, back-end wastewater treatment these processes are often in contact with strong oxidation of concentrated acid, so the chemical pumps require corrosion resistance, safety, energy saving, high efficiency, durability and other characteristics.

QEEHUA PUMP series commonly used in PCB industry
Acid-resistant magnetic pump products are suitable for conveying various corrosive media. The anti-corrosion magnetic drive pump integrates the advantages of various plastics and has the advantages of extra strong corrosion resistance and high mechanical strength, non-aging and non-decomposing toxins. It is the ideal equipment for conveying various strong and weak acids.
The horizontal centrifugal pump is designed according to the principle of centrifugal force. The impeller vane rotating at high speed drives the water and throws it out to achieve the purpose of conveying.
Precision chemical filter is a machine applied in electroplating, surface treatment, PCB etching equipment, pharmaceutical and environmental protection. Its main function is to filter chemical solutions and remove insoluble particle impurities from these solutions.
