Pneumatic diaphragm pumps are a new type of conveying equipment and one of the most innovative pumps available today. Powered by compressed gas, they can safely transport various corrosive liquids, liquids containing large particles, high-viscosity liquids, volatile, flammable, toxic liquids, and optically destructive liquids. BSK offers four main series of pumps: standard pumps, high-pressure pumps, powder pumps, FDA-certified pumps, and 3A-certified pumps. Multiple wet-end options are available to meet diverse application needs. With its advanced air distribution system and stable performance, BSK pumps enjoy a high reputation in industries such as chemical, ceramics, oil and gas, food and pharmaceutical, mining, water treatment, lithium battery production, and construction.
The BSK CP series pneumatic diaphragm pumps are available in 1.5-inch, 2-inch, and 3-inch wet-end sizes, and are available in materials including PTFE, Santoprene, Hytrel, NBR, or Viton. These pumps are designed for chemical production (transporting acids and alkalis), treating corrosive wastewater, and conveying ceramic slurries and oil emulsions.
