PT-200 Series Low Profile Cast Iron Pump Trap


Cast Iron

For pressures to 125 psig (8.5 bar) . . .
Capacities to 3,700 lb/hr (1678 kg/hr)

The Armstrong PT-200 Series Low Profile Pump Trap is a low-maintenance, non-electric solution to moving condensate or other liquids from low points, low pressures or vacuum spaces to an area of higher elevation or pressure. Condensate can be returned well above the 200°F (93°C) limit of conventional electric condensate pumps without the problems of leaking seals or cavitation.

  • 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.
  • Externally removable/replaceable seats. Seats can be replaced or cleaned without removing the mechanism assembly.
