How to choose diaphragm pump materials for different industries? Check the selection guidance!

Aug,09,2023

Diaphragm pumps are widely used. At present, the fields of this equipment are widely used in energy, food processing, paint, porcelain glaze, sewage treatment, acid and alkali chemicals, etc. Taking QBY3 series pneumatic diaphragm pump as an example, according to different models, the maximum working flow can be as high as 1041L/min, the maximum head can reach 84m, the optional diameter range is 3/8'' to 5'', and the diameter of the particles that can pass through is 1.5mm to 9.4mm, it is the best choice for conveying and processing in various industries.
