Summary::
1. QBY Stainless Steel Air Diaphragm Pump for Food & Chemical, Chemical Resistant Diaphragm Pump is a new type of transportation equipment that uses compressed air, smoke, and industrial exhaust gas as power sources.
2. This pump features two diaphragms, where compressed air enters the pump body to drive it in a continuous suction and release action, enabling efficient liquid pumping. It is also safe for use in hazardous environments due to its lack of an electric motor.
3. The QBY air-operated double diaphragm pumps are capable of transferring both free-flowing liquids and more challenging media. They offer the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps.
