Pumps are equipment you use in various cases, from the swimming pool to water supply systems. When you discover a leak in the pump, it is important to look at the mechanical seal that it uses. Failure of a pump seal can cause leakages of water and chemicals in some cases. By understanding what causes the failure of a pump and rotary seal, it is easier for you to reduce the risk of these events. Then if you have any interest in this aspect, stay tuned. 

Common Reasons And Tackling Methods:

There are many reasons why a pump seal may fail to work, most of which can be prevented if you know what can cause a failure in your pump seal. In this section, we will dig out the main reasons. 

      • Pressure

Consistent pressure regulation in a pump is crucial, as when the pressure falls or rises, it can cause issues with the system. This is also where a common cause behind pump seal failures comes in. When you do not regulate the pressure in the pump effectively, it can build up over time. High pressure in the pump can push against the seal that you use. In this case, the water may push the pump seal out of its place. The situation causes the water or chemicals that run through the pump to leak out, which can result in problems with the system. Make sure you have a pressure meter installed on the pump and regularly monitor it for changes. Keep the pressure at an appropriate level to prevent this particular event from happening. 

      • Foreign Components

Another common reason you may find that your pump seal fails to operate effectively is due to foreign components that collect inside, which may be the items that are sucked in from the pool or another water system that you use the pump with. When these components connect inside the pump, they may constantly bump into the seal. This can gradually cause the seal to lose its grip on the pump and eventually pop out. Therefore, regularly opening and cleaning the pump is a good way to look for foreign objects. Besides, choosing pump seals with proper materials can prolong their lifespan. 

      • Spring Compression

When your water system uses a spring compression system, then this can also sometimes lead to problems with the seal. The spring may cause pressure on the area where the seal is located, causing the seal to move out of its place. Properly loading a spring compression into a pump is a good way to reduce the risk of this particular problem. You should also perform regular maintenance and ensure the spring does not show any signs of rust, corrosion, or wear. Replace the spring if you find that it shows signs of damage.
