The product
PT-400 Series Vertical Pump Traps are a low-maintenance, non-electric solution for 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.
Features
- Economical non-electric operation
- No leaking seals, impeller or motor problems means lower maintenance
- Lower installation costs
- Standard unit is intrinsically safe—explosion-proof
- ASME code-stamped carbon steel body vessel
- Internals are all stainless steel for corrosion resistance and long life
- Springs are made from long-lasting Inconel X-750
- All valuable Btu’s are captured and returned to the system
- Can be used in flooded pits without fear of electrocution or circuit breaker defaults
- 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
