PT-516 High Capacity Pump Trap

PT-516 High Capacity Pump Trap
Armstrong

Fabricated Steel

For pressures to 150 psig (10.3 bar) . . .
Capacities to 80,000 lb/hr (36287 kg/hr)

Effective recovery and return of hot condensate are essential to overall plant efficiency and conservation of energy. Large amounts of condensate provide the best opportunities to save energy.

The Armstrong PT-516 High Capacity Pump Trap is the low-maintenance, non-electric solution to moving large amounts of condensate and other liquids from low points, low pressures or vacuum spaces to an area of higher elevator or pressure. Condensate can be returned at temperatures well above the 200°F (93°C) limit of conventional electric 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.
  • Lower installation costs. Single trade required for installation and maintenance.
  • Peace of mind. Standard unit is intrinsically safe—explosion-proof.
  • Durable construction. ASME code-stamped carbon steel body vessel.
  • 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.

Typical applications

  • 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
  • Reboilers
  • Flash tanks

NOTE: Armstrong can also custom fabricate packages to meet your specific needs. Pre-piped conventional, low-boy, closed-loop and custom-fabricated skid packages are available.
