The hot water of condensation is re- moved from the hot wells by four i-in. volute hot-well drainagepumps, direct driven by 3-hp induction motors. These drain-age pumps deliver the condensation to the Webster open heaterfor returning directly to the boilers. Make-up water for theboilers is ordinarily to be taken from the circulating system,this being regulated by the float in the heater; arrangements arealso made for the use of city water for this purpose. Two rotative, dry-vacuum pumps are provided for the re-moval of air and other gases, this pump being of the recipro-.

The steam cylinders of these pumps arefitted with Corliss valve gears for highest economy of oper-ation, and a novelty is introduced in the placing of the vacuumcylinders vertically, the steam cylinders being located horizon-tally, and the connecting rods of the two cylinders beingattached to a common crank-pin. The condenser arrangement at this station is somewhat volute drainage pumps for the removal of the water ofcondensation from the hot wells are located below the level ofthe hot wells, so as to receive their suction by gravity. In thisway the pump always runs a little ahead of the water, and thereis no necessity of floats, valves or other automatic , there is also no possibility of air binding, as inreciproc
