The working principle of the pump involves two symmetrical working chambers, each equipped with its diaphragm. When compressed air enters one of the chambers, it causes the diaphragm to move, leading to the pumping action. As the diaphragm moves forward, it creates a vacuum that draws fluid into the chamber. Once the stroke is completed, the pump switches the air supply to the other chamber, allowing for continuous operation.
In conclusion, the Air-Operated Double Diaphragm Pump QBK-25L is a reliable and efficient solution for various pumping needs in industrial applications. With its robust construction, impressive flow rate, and versatility, it stands out as a top choice for professionals looking for an effective fluid transfer solution.
