Spirax Sarco MFP14 Automatic Pump - Steam & Air Operated Condensate Pump

Overview

The Spirax Sarco MFP14 is a mechanical displacement pump operated by steam or compressed air, designed for reliable condensate recovery in industrial steam systems. Unlike electric pumps, this automatic pump uses motive pressure to lift condensate and other liquids to higher elevations without requiring electrical connections.

The MFP14 series is ideal for draining closed vessels operating under vacuum or pressure conditions. When combined with a float steam trap, the pump effectively handles temperature-controlled heat exchangers across varying load conditions. The pump operates on a simple fill-and-discharge cycle, making it highly reliable with minimal maintenance requirements.

Available in three body materials—SG iron (MFP14), cast steel (MFP14S), and stainless steel (MFP14SS)—the pump suits a wide range of process environments from standard condensate systems to corrosive or high-purity applications.
