Why doesn’t the pneumatic diaphragm pump deliver any flow?
Thread Content
If a pneumatic diaphragm pump stops delivering the desired flow rate despite being in good condition, could it be that something has entered the pump and caused a blockage? Find the reason. Thank you
It mainly checks whether the check valve at the inlet and outlet is functioning properly, as well as whether the diaphragm is worn.
Take it apart and check – is the diaphragm broken?
Prepare a hammer; tap the entrance area a few times when the volume isn’t right
1. Generally, the inlet valve is blocked by impurities, which prevents proper flow. 2. The outlet might be blocked; check if the pressure is high. 3. The diaphragm is damaged. These are the reasons why we haven’t seen an increase in production in recent times.
1. Check if the diaphragm is damaged. 2. Verify whether the stroke is insufficient. 3. Check if the flow rate at the inlet is inadequate
1. Check whether the air supply pressure is sufficient to operate the pump, and whether there are any obstructions in the pneumatic valve that prevent pressure from entering. 2. Check if there are any obstructions in the inlet and outlet ball valves that could cause leakage. 3. Verify whether the inlet and outlet valves are open. 4. Check if the pipelines are blocked or if there is no liquid present. 5. Check if the diaphragm is damaged

There will be liquid at the exhaust port of the diaphragm rupture silencer; it is important to check whether the valve ball and seat are properly sealed
Generally, it’s either the membrane that’s broken or some impurity that’s getting stuck in the ball; just open it and take a look to find out.
