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.

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
• 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.
