When you have a boiler system in place at your business it’s likely that you will also have a loop system. This loop system will move the condensate to and from the boiler. Many systems require the condensate to be as hot as possible when it returns to the boiler. On the other hand, if you have a steam condensate pump you will need the condensate to be cooled upon its return. Here’s how you can determine the size required for a condensate return pump.
The Load Being Moved
The first thing you need to look at when choosing a condensate pump is the load that is being moved. Every boiler on the market has a rating that determines how much it can output when it comes to steam. The rating is either labeled as horsepower, BTUS, or pounds per hour of steam. Before picking a condensate pump you will need to determine the capacity of the boiler so the pump matches the output.
The Rate of Evaporation
Even though you’ve already determined how much output the boiler has, you still don’t want to make the pump purchase just yet. It is recommended that you buy a pump that has two or three times more than the evaporation rate of the boiler. This will allow the pump to send the condensate back to the boiler quicker than it can output it.
Discharge Pressure
Another thing you must look at when choosing the size of a condensate return pump is the discharge pressure that is required. You can calculate this by looking at the following items:
The final few steps needed to determine the right size pump is to determine the return temperature of the condensate and consider the size of the tank

Discharge Pressure
Another thing you must look at when choosing the size of a condensate return pump is the discharge pressure that is required. You can calculate this by looking at the following items:
- The lift of the static head
- The piping friction loss
- Pressure that needs to be overcome in the vessel that does the receiving
