In these days of energy conservation, hot condensate is too valuable to be lost as it contains more than 25% of heat used in creating steam. Also it is distilled water that makes excellent feed water for boilers.
These are pumps used to pump condensate to the desired location and are cheaper to operate as against electrically operated pumps which require special impellers to avoid risk of cavitations by condensate. |

These are basically vessels with a float assembly. When condensate level raises the float rises activating a valve through which a short burst of pressurized steam /air is let in which in turn pumps the condensate through the vessel. The flow of condensate is regulated by two check valves at the inlet and outlet of the vessel. |
