Product details
QBK Pneumatic Diaphragm Pump Product Overview
The QBY3 pneumatic diaphragm pump produced by our unit is a new type of conveying machinery that uses compressed air as the power source. It can pump and absorb various corrosive liquids, granular liquids, high viscosity, volatile, flammable, and highly toxic liquids. Its performance parameters are similar to WLLDENPVMPS from the Federal Republic of Germany and MARlOWPUMPS from the United States.

Note: ○ - longer lifespan, △ - average lifespan, × - unavailable. This table only considers corrosion resistance. Due to the poorer elasticity of polytetrafluoroethylene compared to rubber, the actual service life varies due to factors such as pressure, pump stroke impurities, etc. Food rubber is specifically designed for the food and beverage industry.
