Can the medium in a diaphragm metering pump flow back?
Reply #22017-04-10
Diaphragm pumps have a check function; specifically, a seal is formed between the ball and the rubber ring, which allows the diaphragm to force the medium into the discharge pipeline. Based on this design principle, as long as nothing unexpected happens, there should be no backflow.

Under normal circumstances, it won’t. However, it is not ruled out that the check valve may have failed or been installed incorrectly.

The outlet valve of a metering pump can be considered a one-way valve, and backflow generally does not occur

Under normal circumstances, there is no backflow. If there is a backflow, it is generally necessary to check for the problem.

No, both the inlet and outlet are one-way valves; reverse flow requires repair

It won’t flow back; if it does, the process conditions won’t be met

In principle, it cannot flow in reverse, as there are check valves on both the inlet and outlet
