PT-104 Series Mini Pump Trap


Cast Iron

For pressures to 100 psig (7 bar) . . .
Capacities to 1,800 lb/hr (816 kg/hr)

The patented Armstrong PT-104 Mini Pump Trap is 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 200°F (93°C) limit of conventional electric centrifugal pumps without the headaches of leaking seals or cavitation problems. The PT-104 Mini Pump is the small solution for big problems.

  • Economical non-electric operation. Uses inexpensive steam air or inert gas.
  • Low-maintenance operation. No leaking seals, impeller or motor problems means lower maintenance. No NPSH issues.
  • Space-saving size. Low-profile body fits in tight spaces while allowing minimal fill head.
  • Lower installation costs. Single trade required for installation and maintenance.
  • Peace of mind. Standard unit is intrinsically safe—explosion-proof.
  • Cast iron durability. Rugged construction material means long service life.
  • Corrosion resistance. Internals are all stainless steel for corrosion resistance and long life.
  • Heavy-duty springs. Springs are made from long-lasting Inconel X-750.
  • Efficiency. A closed loop means no motive or flash steam is lost. All valuable Btu’s are captured and returned to the system.
  • Safety. The pump can be used in flooded pits without fear of electrocution or circuit breaker defaults.
