Troubleshooting Common Issues with Fristam Pump Seals

Fristam pumps are known for their reliability, quality, and durability. However, like any other machine, they can develop problems, especially with the seals. The seals play a critical role in the operation of the pump, and if any of them malfunction, it can lead to leakages, contamination, and even pump failure. In this article, we will look at five common issues that affect Fristam pump seals and how to troubleshoot them.

1. Seal Leakage

Seal leakage is one of the most common problems associated with Fristam pump seals. There are several reasons why seals might start to leak. One of the primary causes is mechanical wear and tear. Over time, the seals can wear out, and as a result, their ability to seal the pump is reduced. This wear and tear are often accelerated by friction and heat. The higher the friction, the more heat is generated, and the faster the seals will deteriorate.

Another cause of seal leakage is improper installation. If the seals are not installed correctly or there are gaps between the seals and the pump, there can be leakages. Also, if the seals are not tightened properly, they can loosen over time, leading to leakages.

To troubleshoot seal leakage, first, check if the seals are worn out or damaged. If they are, replace them immediately. Also, check if the seals are tightened correctly and if there are any gaps. If there are gaps, seal them using proper sealing materials. If there are no gaps and the seals are not damaged, consider reducing the friction and heat generated by the pump by reducing the speed or lubricating the pump.

2. Seal Contamination

Another issue that is common with Fristam pump seals is contamination. When the seals are contaminated, they tend to wear out quickly, leading to seal leakage. Contamination can come from various sources, including pumped fluid, lubricants, and cleaning agents.

To troubleshoot seal contamination, start by identifying the source of the contamination. If it's the pumped fluid, consider switching to a more compatible fluid that will not react with the seals. Also, ensure that the lubricants and cleaning agents used are not harmful to the seals. Lastly, clean the pump regularly to prevent the buildup of contaminants.

3. Seal Wear

Seal wear is a natural occurrence, and it often happens with the constant use of the pump. However, excessive wear can lead to seal leakage and, ultimately, pump failure. Several factors can cause excessive wear, including friction, heat, and chemical attack.

To troubleshoot seal wear, start by identifying the factors contributing to the wear. If the problem is friction and heat, consider reducing the speed of the pump or lubricating it to reduce the friction. If the problem is chemical attack, consider using a more compatible material for the seals or switching to a more compatible pumped fluid. If the seals are worn out, replace them immediately.

4. Seal Cracking

Seal cracking is a severe issue, and if not addressed immediately, it can cause total pump failure. The cracking is often caused by material aging, and it's more common with older pumps that have been in use for several years.

To troubleshoot seal cracking, start by inspecting the seals regularly and replacing them if they show any signs of cracking. Also, consider replacing the seals after a certain period, even if they don't show any signs of cracking. Lastly, consider using more durable seal materials that can withstand aging and wear.

5. Seal Hardening

Seal hardening is another common issue with Fristam pump seals. It often happens when the pump is not used frequently, and the seals are not lubricated enough. When this happens, the seals become hard, and their ability to seal the pump is reduced.

To troubleshoot seal hardening, start by lubricating the pump regularly, even when it's not in use. Also, consider using seal materials that are resistant to hardening and aging. Lastly, when storing the pump, ensure that it's stored in a clean and dry area to prevent the buildup of contaminants that can contribute to seal hardening.

In conclusion, Fristam pump seals play a critical role in the operation of the pump, and any issues with the seals can lead to leakages, contamination, and pump failure. To avoid these problems, it's critical to troubleshoot any issues with the seals immediately and implement preventative measures to prevent their occurrence. By doing so, you can prolong the lifespan of your pump and minimize downtime and repair costs.
