Description
Spirax Sarco APT14, APT14HC, and APT14SHC automatic condensate pump traps are rated PN16 and available with flanged or threaded connections. The device automatically switches between trap and pump cycles according to line pressure. Using steam as the motive force, it removes condensate from process equipment under all operating conditions, including vacuum conditions.

Rated Displacement
| Model | APT14 | APT14HC and APT14SHC |
|---|---|---|
| Pump displacement/cycle | 5 liters | 8 liters |
| 1 m installation height, 5 bar g motive steam, 1 bar g backpressure | Maximum trap mode capacity 4000kg/h; maximum pump mode capacity 1100kg/h | Maximum trap mode capacity 9000kg/h; maximum pump mode capacity 2800kg/h |
Note: The capacities shown in the table are achievable by the automatic condensate pump trap under the specified installation conditions. The applicable conditions are listed in the first column of the table above. Capacity varies with installation conditions and parameters; consult Spirax Sarco for application-specific information and capacity. To achieve the rated capacity, the total lift or backpressure BP of the automatic condensate pump trap, consisting of static head and pressure in the condensate return line, must be lower than the motive steam pressure.
Height (H)m×0.0981 + pressure in condensate return line§bar g + downstream line flow friction resistance (Pf)bar. The downstream line flow friction resistance Pf may be disregarded if the downstream line is less than 100 mm long, the condensate line is not flooded, and the effect of flash steam at the heat exchanger’s maximum operating load has been considered during pipe sizing.
Product Description
-
APT14 and APT14HC: Maximum steam operating pressure is 13.8 bar g, with no electrical power required. The pump body is made of ductile iron (EN JS 1025 or ASTM A395). The inlet has a swing check valve, and APT14 outlet has a ball check valve. The integrated trap mechanism includes two stainless steel floats and a two-stage trap. The integrated pump mechanism is a stainless steel spring-loaded quick-action mechanism with no external seals or packing.
-
APT14SHC: Maximum steam operating pressure is 13.8 bar g, with no electrical power required. The pump body is made of carbon steel (EN 1.0619 or ASTM A216 WCB). The inlet has a swing check valve. The integrated trap mechanism includes two stainless steel floats and a two-stage trap. The integrated pump mechanism is a stainless steel spring-loaded quick-action mechanism with no external seals or packing.
