ATO diaphragm dosing pump is a metering pump used for chemicals, which comes with a flexible diaphragm instead of a piston. The diaphragm moves back and forth to change the volume of the pump chamber and sucks and discharges liquid under the action of the pump inlet and outlet valves.

Tips: Can metering pumps run dry?
Metering pumps are designed to accurately dispense precise amounts of liquid chemicals or substances. Running them dry, meaning operating them without the intended liquid, can damage the pump and compromise its functionality. These pumps typically rely on the liquid they are meant to pump to lubricate and cool their internal components. Running dry can lead to overheating, seal damage, and accelerated wear and tear on the pump’s parts. Additionally, it may result in inaccurate dispensing, which is especially problematic when precise dosing is essential, such as in water treatment or chemical processes. To prevent damage, it’s crucial to ensure that dosing pumps are always primed with the appropriate liquid and that they have safeguards, like pressure relief valves or low-level sensors, to alert operators or shut down the pump when the liquid supply is insufficient, reducing the risk of running dry.
