    Tips: Do diaphragm dosing pumps create suction?

    Diaphragm dosing pumps are positive displacement pumps commonly used for accurate and controlled fluid dosing in various industrial applications, including water treatment and chemical processing. These metering pumps work by using a flexible diaphragm to displace a specific volume of fluid with each stroke.

    Diaphragm dosing pumps do create suction as part of their operational cycle. During the suction stroke, the diaphragm moves away from the pump chamber, creating a low-pressure area within the chamber. This low pressure causes the inlet check valve to open, allowing the pump to draw in the desired fluid or chemical from a source like a storage tank or reservoir. This suction action is vital for the pump's ability to pull in the precise amount of liquid needed for dosing purposes.

    Therefore, diaphragm metering pumps utilize a suction mechanism during their operation to draw in the fluid they are designed to dose accurately, making them suitable for applications that require precise control over the injected fluid volumes.
