Steam Operated Pump Trap SOPT
Normal float traps fail to work under vacuum/stall conditions on the process application. Under such circumstances, the steam trap is either byepassed or the the process vessel gets water-logged leading to multiple issues.
The Forbes Marshall Steam Operated Pump Trap is an innovative product which can work either in trapping or pumping modes automatically, depending on the pressure difference across the trap.
In case vacuum/stall condition arises, SOPT uses the pressure of motive steam to discharge the condensate. Under normal circumstances, it operates like any other float trap. SOPT can significantly improve productivity and product quality of processes prone to stall and vacuum conditions.
- Available as a pre-engineered, ready to comission skid mounted assembly for optimum performance.
- Also available with a two orifice mechanism for handling peak and running condensate loads (patent applied)
- Enhanced discharge capacity Robust and compact construction.
- Built-in check valve Available as skid mounted unit.
- Significant improvement in the batch time and productivity in stall/vacuum prone applications.
- Enables maintaining of temperature gradients and product quality.
- Eliminates opening of trap bypass valve during stall, resulting in steam and condensate savings Improved equipment uptime

Frequently Asked Questions
Putting a non return valve at the trap outlet will only prevent the condensate from flowing back into the process and flooding it. It does not aid the condensate evacuation in stall situations. On the other hand, a steam operated pump trap uses the high pressure live steam to evacuate the condensate in stall situations.
