Problem 1: The pump can operate, but output flow is low.

Problem 2: The pump works only a few seconds and stops.

Problem 3: Pump operation frequency is irregular, and flow output is unstable.

This video is a 3D demonstrative video about two fault situations in ball valve blockages. In the future, a series of explanatory videos will be released to help everyone make a preliminary judgment when a malfunction occurs. If you have any pump-related questions you would like to consult on, feel free to contact DYI SHENG.


Pipeline blockage

Generally, the cause of pipeline blockage is usually because of particles or impurities in the fluid that block the ball valve, stopping the ball valve to function correctly, which is to stop fluid from reversing, thus resulting in an unsmooth delivery process. It is recommended to clean under safe conditions to remove impurities or any material stuck near the ball valve, after which your pump may restore normal operation. If the condition cannot be resolved after cleaning, it is recommended to send it back to us DYI SHENG for repair or replacement of damaged parts.

Pneumatic diaphragm pumps can be used to transport fluids containing particles, but there are still limitations on the allowable particle size. When the conveying fluid contains too large particles, it may cause blockage and affect the operation of the diaphragm pump.

If your pump often sucks in larger particles and causes blockage of the ball valve components, it is strongly recommended that you install a filter on the inlet side, which will greatly improve the situation.

If this type of issue often occurs to the pump you use, please be sure to check regularly and replace the worn parts in time to avoid other failures caused by the damaged parts, which might increase your cost; you can also contact our sales and replace these parts with suitable material that are much more durable.
