PT-300 Series Horizontal, 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 condensate pumps without the headaches of leaking seals or cavitation problems.
