HONGSHENG The pneumatic pump uses an oil-free pressure chamber, eliminating the need for lubrication. It operates at low pressure and speed without jamming. The central shaft is made of stainless steel, which is corrosion-resistant, ensuring a long lifespan for the diaphragm. The body can be made from either engineering plastic or aluminum alloy, providing excellent corrosion resistance and making it suitable for high-pollution environments. With fewer parts, assembly is easy, and maintenance is convenient. Various models offer different flow rates. *The small model has a flow rate of 27L/MIN, while the large model has a flow rate of 1080L/MIN. Models include HS10PP, HS15PP, HS25PP, HS40, HS50, and HS80. They have strong self-priming capabilities and can be fitted with different materials for the liquid contact parts based on the medium being transported, such as PP, PVDF, SUS316, aluminum alloy, or PTFE diaphragms and rubber membranes. HONGSHENG The pneumatic pump is widely used in wastewater treatment, shipbuilding, food, paint, textiles, ceramics, electroplating, PCBs, chemicals, pharmaceuticals, electronics, and eyewear industries.
