Steam Traps can discharge condensate only when the inlet pressure is higher than the outlet pressure i.e when there is a positive differential pressure across the trap. In certain applications which are temperature controlled, there is a possibilty of the process side pressure becoming either equal to or less than the back pressure on the trap, this phenomenon is called as stall or vaccuum. Normal steam traps are unable to discharge condensate under stall conditions which results in waterlogging and leads to increased batch timings, damage to the process equipment and rejections.
Forbes Marshall Steam Operated Pump Trap discharges condensate even under stall conditions or vaccum. Under normal working conditions, the steam operated pump trap works as a normal float trap. During the stall situations, the condensate accumulation lifts the float to the maximum height and actuates the motive steam connection. The condensate accumulated inside is pumped out by the pressure of the motive steam.
