Pneumatic diaphragm pump suction pipe diameter of not less than the pump inlet port diameter, such as the delivery of high-viscosity fluid, the suction pipe diameter is preferably greater than the pump inlet diameter. Suction piping on the inlet side must be durable and free of wrinkles to create a high vacuum condition. The diameter of the outlet pipe should be at least equal to the outlet diameter or slightly larger to reduce the friction loss. All piping and fittings must be leak-tight or pump self-priming will be reduced. Pneumatic diaphragm pump installation: If you ignore the installation details, a long period of careful planning, research and selection will still result in poor pumping effect and may affect the life of the pump. Location: Noise, safety and other logic often have requirements for where the equipment should be installed. Parallel installation with conflicting requirements may result in blockage in the area of ​​use, affecting the installation of other pumps. Use: First, the location of the pneumatic diaphragm pump must be easy to use, so that maintenance personnel will facilitate routine inspection and commissioning. Air Supply: Each pneumatic diaphragm pump shall have a vent tube and the vent tube shall provide sufficient air volume to achieve the desired pump flow. Air pressure according to different pumping needs, but not more than 7BAR. (125PSI) Installation height: Take full account of the self-priming ability of the pneumatic diaphragm pump to avoid the problem of self-priming reduction. Piping: The pump position can not be finalized until after considering each possible location of the piping problem. The best installation should be selected at the junction of a shortest and most straight import and export pipeline. Should try to avoid the extra elbow and pipe fittings facilities. The pump body should be able to support all piping independently. Also, the piping should be ordered to avoid stress on the pump piping. Active hoses can be installed to eliminate stress from the pump's natural movement back and forth. To attach the pump body to a fixed base, placing a cushion between the pump body and the base will help reduce body vibration.
