The Armstrong Double Duty® series steam trap/pump combinations are a low maintenance, low-profile solution for draining heat exchangers in various applications. The Double Duty® series offers you the versatility of combining a pump within a steam trap to aide in condensate drainage from a heat exchanger under all operating conditions (100% turndown).
Economical. non-electric operation
Low-maintenance operation. No leaking seals, impeller or motor problems. No NPSH issues.
Space-saving size. Low-profile body fits in tight spaces while allowing minimal fill head.
Lower installation costs. Single trade installation.
Peace of mind. Intrinsically safe.
Ductile iron durability. Rugged construction material means long service life.
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 trap/pump can be used in pits or sumps without fear of electrocution or circuit breaker defaults.
Typical applications
Low-pressure heating systems
Process heat exchanger or coils with modulating steam control
Systems under vacuum
Hazardous (explosion-proof) areas
Flash tanks
