Diaphragm metering pump can use a diaphragm to completely isolate the flowing liquid from the driving lubrication mechanism. It adopts a high-tech structural design and uses the latest PTFE and rubber composite diaphragm, which has strong corrosion resistance and greatly improves the efficiency of the diaphragm. This diaphragm dosing pump is widely used for water treatment plant, boiler, or handing chemicals.

Tips: Are diaphragm dosing pumps self-priming?
Diaphragm dosing pumps are generally not self-priming devices. Unlike some other types of pumps, such as centrifugal pumps, which can automatically draw in fluid and create suction, diaphragm metering pumps require manual priming or the assistance of a separate priming mechanism.
Diaphragm metering dosing pumps work by using a flexible diaphragm to displace a specific volume of fluid with each stroke. However, they do not inherently have the ability to create the necessary suction to pull in the fluid from the source on their own. This means that before operation, the pump needs to be filled with the liquid it is intended to dispense, or a priming procedure must be followed to ensure the pump chamber is filled and free of air.
Failure to prime a diaphragm metering pump correctly can lead to inaccurate dosing and potential damage to the pump. Therefore, it's crucial to follow the manufacturer's instructions for priming to ensure the pump functions accurately and reliably.
