2. General product information

2.1 Description

The Spirax Sarco MFP14-PPU vented automatic pump packaged units are plug-in systems 

specifically designed to collect and pump hot condensate; commonly returned for use as 

boiler feedwater.

The MFP14-PPU is available with either single, duplex or triplex pumps, mounted on a single 

base plate, that can be used for duty only or duty / stand-by applications.

Operated by steam, the MFP14-PPU can be tailored to suit a wide range of condensate 

handling applications.

The standard pump is manufactured from SG iron, although cast steel and stainless steel 

versions are available on request.

Please note: 

Versions suitable for use with compressed air as the motive power and or other 

combinations are available as bespoke items. For further details contact your local Spirax
