Keeping a Condensate Return Pump Running Efficiently

If you have a condensate return pump system in place it's time for you to learn the proper way to clean the machine. Keeping your steam condensate return pump clean is an important part of ownership. The longer you go in between cleanings the more likely it is that the pump will not run efficiently. If you follow these cleaning tips your condensate return pump should run efficiently at all times.

Clear the Sediment

There is a strainer installed on all condensate pumps. The strainer is used to catch dirt, dust, debris, and other items that could make their way into the system. The strainer stops this debris from getting into the receiver of the condensate pump. If the debris or sediment gets into the receiver it can cause the pump to work inefficiently. After you are done using the heat each year the strainer should be cleaned.

Check Condensate Temperature

If your steam condensate return pump is still not working efficiently you should check the temperature of the condensate being produced. If the condensate temperature gets too hot the pump would cavitate. Cavitation occurs when the pump attempts to pump the water but it becomes vapor too quickly. You will hear a sound much like gravel is moving through the pump.

Check the Seal

The seal of the pump is very important when ensuring that it runs efficiently. Carbon dioxide is released when the boiler in the system produces steam. Carbonic acid will be formed when carbon dioxide mixes with condensate on the return side of the pump. Carbonic acid can eat through return lines and create leaks. The seal of the steam condensate return pump can also be affected by the carbonic acid. You need to check the pH of the water to ensure that the seal is not compromised.
