The Armstrong PT-300 Series Horizontal, Low Profile Pump Trap
is the 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.
