Why Diaphragm Pump Not Working: Common Solutions

If you've noticed that your diaphragm pump isn't working as it should, don't panic! There are some common reasons why this might be happening, and simple solutions that can help get your pump up and running again in no time.

Clogged Inlet or Outlet Valves.

One of the most common reasons why a diaphragm pump may not be working properly is due to clogged inlet or outlet valves. This can happen if the pump is not properly maintained or if debris gets stuck in the valves. To fix this issue, try cleaning the valves with a brush or a small tool to remove any build-up. Make sure to also check for any obstructions in the tubing that could be causing the problem.

Faulty Diaphragm.

Another common issue that can cause a diaphragm pump to stop working is a faulty diaphragm. If the diaphragm is torn or damaged in any way, it will not be able to create the suction needed to pump liquids effectively. In this case, the diaphragm will need to be replaced with a new one. Be sure to check the manufacturer's instructions for the correct replacement part to use.

Air Leaks.

Air leaks can also cause a diaphragm pump to malfunction. If air is leaking from the pump or the tubing, it can prevent the pump from creating the necessary suction to move liquids. Check for any signs of air leaks and tighten any connections that may be loose. You may also need to replace any damaged tubing or seals to fix the issue.

Low Air Pressure.

If your diaphragm pump is not working, it could be due to low air pressure. Make sure that the air compressor providing air to the pump is functioning properly and that the pressure is at the recommended level. Adjust the air pressure as needed to ensure that the pump is receiving enough air to operate efficiently.

Wrong Type of Fluid.

Using the wrong type of fluid in a diaphragm pump can also cause it to stop working. Make sure that you are using the correct type of fluid that is compatible with the pump. Using a fluid that is too thick or corrosive can damage the pump and prevent it from operating correctly.

In conclusion, if your diaphragm pump is not working, there are several common reasons why this might be happening. By checking for clogged valves, a faulty diaphragm, air leaks, low air pressure, or the wrong type of fluid, you can troubleshoot the issue and get your pump back in working order.
