The QBK Air Operated Double Diaphragm Pump is a versatile and reliable solution for transferring various liquids, including those in the food and chemical industries. This pump is powered by compressed air, making it ideal for use in hazardous environments where electric motors are not suitable. Equipped with two diaphragms, this pump operates through a continuous suction and discharge cycle driven by compressed air. Its design allows it to handle both free-flowing and difficult-to-pump media, offering the advantages of self-priming, submersible, shielded, slurry, and impurity pumps all in one. It is widely used in industries such as chemical processing, painting, printing, and oil handling due to its high resistance to corrosion and durability.
