FLASHJET™ Pump
The Forbes Marshall FlashJet™ Pump (FJP) is an innovative, award-winning integrated closed-loop system combining a pressure-powered condensate pump and a flash vessel to achieve 100% simultaneous recovery of flash steam and condensate.
In industries where steam is a key utility, up to 20% of the total energy from generated steam remains trapped in condensate and flash steam. Unlike conventional electrical pumps that vent valuable flash steam to the atmosphere (wasting 8-10% of available energy) and drop condensate temperatures to 55-75°C (131-167°F), the FlashJet™ Pump operates entirely on steam.
By separating flash steam via a gravity settling method and using a mechanical float mechanism to pump condensate, the FJP ensures that high-temperature condensate (+100°C / +212°F) is returned directly to the feed water tank. This zero-vent, zero-loss design eliminates cavitation risks, reduces fuel consumption, and maximizes the Condensate Recovery Factor (CRF) across process industries.

Flash steam can be recovered through carefully designed systems that capture and reuse the steam for other processes, improving energy efficiency and reducing waste. The steps to recover flash steam in industrial processes include condensate collection, pressure reduction, and separating flash steam from condensate.
Recovered flash steam can be used in low-pressure applications for process heating or drying, in heat exchangers to preheat boiler feedwater or be supplied directly to auxiliary equipment like small turbines or ejectors.
To ensure complete recovery of flash steam and condensate, use correctly sized flash vessels, insulated piping, efficient steam traps, and dedicated return systems. Regular maintenance, monitoring, and automated controls optimise recovery.
The Forbes Marshall FlashJet™ Pump is an integrated system that combines a pressure-powered condensate pump with a flash vessel. It ensures closed-loop recovery of flash steam and condensate, optimizing energy balance and reducing wastage.
The FJP25 is the most compact model, offering a 10-liter (3.962 gal) discharge per cycle and a smaller footprint, making it ideal for localized, lower-load equipment recovery.
Electrical pumps often vent valuable flash steam to the atmosphere (wasting 8-10% of energy) and cause the condensate temperature to drop significantly, requiring extra fuel to reheat the water. The steam-operated FlashJet™ Pump recovers 100% of both flash steam and condensate, returning it at high temperatures (>100°C / >212°F) while eliminating electrical costs and cavitation risks.
No. The pump operates mechanically using steam (or air) as the motive fluid to push the condensate, making it ideal for hazardous areas and immune to power fluctuations.
Condensate flows into the flash vessel assembly where flash steam naturally separates from the liquid by gravity settling. The flash steam is vented out to a low-pressure process, while the remaining condensate triggers a float mechanism that opens a motive steam valve to pump the liquid back to the feedwater tank.
Yes. The system can be paired with the Condensate Recovery Meter (CRM485R), including explosion-proof versions, which accurately measures the amount of condensate and energy recovered.
