Mini Pump Trap – EPT-104

The patented Armstrong EPT-104 Mini Pump Trap is one of the smallest non-electric solution that can move condensate or other liquids from lower to higher points, and from lower to higher pressures. Condensate can be returned at temperatures well above the 210˚F (99˚C) limit of conventional electric centrifugal pumps without the headaches of leaking seals or cavitation problems. The EPT-104 Mini Pump Trap is the small solution for a big problem.


  • Economical non-electric operation
  • No leaking seals, impeller or motor problems means lower maintenance
  • Low-profile body fits in tight spaces while allowing minimal fill head
  • Lower installation costs
  • Standard unit is intrinsically safe—explosion-proof
  • Cast iron construction means long service life
  • Internals are all stainless steel for corrosion resistance and long life
  • Springs are made from long-lasting Inconel X-750.
  • All valuable Btu’s are captured and returned to the system
  • The pump can be used in flooded pits without fear of electrocution or circuit breaker defaults


  • Low-pressure heating systems
  • Process heat exchanger or coils with modulating steam control
  • Remote installations (tracing, tank farms, or remote coils)
  • Systems under vacuum
  • Hazardous (explosion-proof) areas
  • Caustic environments
  • Sumps or submersed areas
  • Flash tanks


  • CE
