2 Possible Reasons Why Your Factory Equipment's Miniature Diaphragm Pump Keeps Overheating

If your factory's equipment utilizes miniature diaphragm pumps, you may have noticed that one has started to switch itself off during operation. After inspecting the part, you may have determined that its sensors are registering high heats and triggering the safety turn-off mechanism.

While this safety feature helps keep the pump from burning out, it does indicate an underlying issue. If this keeps happening, there are a couple of possible reasons why the equipment's pump is constantly overheating.

1.  Ventilation Ports Are Clogged Up With Dust and Debris

The first possible reason why the diaphragm pump keeps overheating and switching itself off is also the easiest to correct. The problem may be that the ventilation ports have become clogged up with dust and debris.

When this happens, the pump is unable to pull in enough air to cool itself off. Because there is not enough air flowing through the pump, the part's internal temperature will become much greater than it can handle, resulting in the safety switch being activated.

To see if clogged up ports are causing the issue, use a small vacuum to gently clean them. Do not wipe the ports, as this runs the risk of pushing the dust and dirt into the pump and contaminating the motor.

2.  Motor Is Not Receiving the Recommended Amount of Power

If cleaning the ventilation ports does not solve the issue of the pump overheating and switching itself off, the next possible reason why this keeps happening could lie with the motor. In this case, the motor may not be receiving the recommended amount of power.

If the motor is not receiving enough electrical current to fully operate, it will run for longer and harder than it was designed to do. When this happens, the strain on the motor will cause it to run too hot, so the safety switch will activate to shut it down.

If you suspect that this is the case, the cord running to the pump may be defective. If you suspect that this may be the case, try replacing the power cord to see if this fixes the issue.

If the pump continues to overheat and making the necessary adjustments to the ventilation system and/or power source does not remedy the problem, you will more than likely need to replace it.
