The product
PT-3500 Series Low Profile Pump Traps are a low maintenance, non-electric solution to move 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 pumps without the headaches of leaking seals or cavitation problems.
Features
- Economical non-electric operation
- No leaking seals, impeller or motor problems means lower maintenance
- Low-profile body fits in tight spaces while allowing minimal fill head
- Lower installation costs
- Standard unit is intrinsically safe
- Rugged construction material means long service life
- 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
- The pump can be used in flooded pits without fear of electrocution or circuit breaker defaults
- Externally removable/replaceable 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
- Flash tanks
