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 uses compressed air, smoke, or industrial exhaust gas as its power source, making it ideal for hazardous environments where electrical equipment may not be safe. Featuring two diaphragms, this pump operates by alternating between suction and discharge cycles, allowing it to handle both free-flowing and difficult-to-pump materials with ease. It combines the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps, offering a wide range of applications.
