Prevent Costly Damage: Tips for Diaphragm Pump Dry Running.

Diaphragm pumps are a popular choice for fluid transfer because of their versatility and durability. However, one issue that can occur with diaphragm pumps is dry running, which can lead to costly damages. In this article, we will provide tips on how to prevent diaphragm pump dry runningdiaphragm pump dry running.

What is dry running?

Dry running occurs when the pump operates without sufficient liquid to cool and lubricate the internal components. This can lead to increased friction and heat, which can cause damage to the diaphragms, valves, and other parts of the pump. Dry running can also cause cavitation, which can damage the impeller and reduce the pump's efficiency.

Tip #1: Monitor the liquid level.

One of the easiest ways to prevent dry running is to monitor the liquid level in the pump. Ensure that the pump is filled with enough liquid before starting the pump. Also, check the liquid level periodically during operation to ensure that there is always enough liquid to keep the pump working efficiently. Monitoring the liquid level can prevent costly damage to the pump and save time and money.

Tip #2: Use a pressure switch.

Another effective way to prevent dry running is to install a pressure switch in the pump's discharge line. A pressure switch can detect when the liquid level drops below a certain point and automatically shut off the pump. This prevents the pump from running dry and causing damage.

Tip #3: Regularly replace diaphragms and valves.

Diaphragms and valves are essential components of the diaphragm pump. Over time, they can wear out and become less effective. This can lead to leakage and increased friction, which can cause dry running. To prevent this, it is crucial to regularly replace the diaphragms and valves. By doing so, the pump will operate smoothly and efficiently, leading to a longer lifespan.

Tip #4: Properly prime the pump.

Another way to prevent dry running is to ensure that the pump is properly primed before starting. Priming means filling the pump with liquid before starting the pump. This ensures that there is always enough liquid to cool and lubricate the pump's internal components. If the pump is not properly primed, it can lead to dry running and costly damages.

In conclusion, preventing diaphragm pump dry running is crucial to prolonging the life of the pump and saving on repair costs. By monitoring the liquid level, using a pressure switch, regularly replacing diaphragms and valves, and properly priming the pump, you can ensure that your pump is operating efficiently and effectively.
