Pneumatic diaphragm pumps are a new type of conveying equipment and one of the most innovative pumps available today. Using compressed gas as a safe power source, they can convey 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 series PP & PVDF pumps are available in diameters of 1/4 inch, 1/2 inch, 1 inch, 1 1/2 inch, 2 inch, and 3 inch, and can be equipped with either an aluminum alloy or polypropylene center housing. Our high-purity polypropylene and polyvinylidene fluoride materials offer excellent corrosion resistance when conveying highly corrosive liquids.
