PT-300 Series Horizontal Steel, Low Profile Pump Trap

Fabricated Steel

For pressures to 125 psig (8.5 bar) . . .
Capacities to 16,600 lb/hr (7529 kg/hr)

The Armstrong PT-300 Series Horizontal Low Profile Pump Trap is the
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 at temperatures
well above the 200°F (93°C) limit of conventional electric condensate
pumps without leaking seals or cavitation 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.
• 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.
