Discharge and lift condensate

UNA 25 PK ball float steam traps with pump function primarily functions as a steam trap. 

However by integrating this steam trap with an automated pump function you can discharge condensate, even under reduced steam pressure or high back pressure. 

The condensate is then efficiently pumped out of the body using the aid of motive steam.

The UNA 25 PS has a pump function to return condensate with motive steam.

What are the features?

  • Easy installation due to standard flange length
  • Corrosion resistant
  • Integrates with non-return valves
