Condensate and heat recovery systems

Explore Spirax Sarco condensate pumps, pump traps and condensate recovery systems, including mechanical condensate pumps and electrical condensate pumps.

How to choose the right condensate recovery route

Condensate recovery selection becomes easier when the project starts with operating condition rather than pump type alone. The main decision is whether the condensate can still discharge by trap action, or whether stalled conditions and return-line pressure now require a pump-based solution.

Recovery routeBest fit whenMain selection priorityNext route
Mechanical condensate pumps and pump trapsDifferential pressure collapses, backpressure rises or vacuum conditions stop normal trap drainageReliable drainage without electric motors, especially with very hot condensate or difficult installationsBrowse mechanical condensate pumps
Electrical condensate pumpsLarger condensate volumes must be returned from receivers or collection systemsHigher-volume pumped return for boiler or process feedwater reuseBrowse electrical condensate pumps
Standard steam trapsNormal differential pressure is still available and active pumping is not requiredEfficient condensate discharge without adding pump complexityBrowse steam traps

Typical routes from common condensate-recovery searches

Condensate recovery searches usually narrow once the user identifies whether the problem is stalled drainage or straightforward pumped return. Use pressure powered pumps when low differential pressure, backpressure or vacuum stop normal trap discharge. Compare electric condensate pumps when the duty is a larger receiver-based return arrangement.

If ordinary drainage is still possible, check steam traps before adding pump complexity. When the recovered condensate is being integrated into the wider boiler house, review deaerators and the surrounding boiler controls that govern reuse on the feedwater side.
