, heater drain pumps and feed pumps operating with direct-contact feed heaters, must be arranged below the water level as the static head of water is the only force available to cause the water to flow into the pump, because the water and the steam on the surface are at the same temperature. before liquid

can flow into a pump, the air or vapour in the suction line must be evacuated sufficiently to cause the liquid to flow into the suction chamber. some pumps (known as self-priming pumps) do this automatically when they are started. in others special priming devices must be used to withdraw the air and...
