The QBK Air Operated Double Diaphragm Pump is a reliable and versatile solution for transferring various types of liquids, including those that are corrosive or difficult to handle. It operates using compressed air, making it ideal for use in hazardous environments where electric motors could pose a risk.
This pump features two diaphragms that work in tandem, driven by compressed air to create a continuous suction and discharge cycle. This design allows the pump to efficiently move both clean and viscous fluids, as well as some solid-laden materials.
The QBK series combines the advantages of self-priming, submersible, shielded, slurry, and impurity pumps, offering a flexible and durable option for industrial and commercial applications.
