Boiler Feed Pumps

For Boiler Feed units, the operation of the pump is controlled by the water level control device which is part of the boiler control package. When the boiler requires water, the pump switches on pumping water from the receiver into the boiler. On Duplex boiler feed units, an Electrical Alternator is used to activate one pump at a time in alternating fashion. The receiver tank also contains an internal make-up water valve actuated by a stainless steel float. This is used if the amount of condensate being returned to the receiver tank is inadequate.

How Boiler Feed Pumps Work

For Boiler Feed applications, the operation of the pump is controlled by the water level control system on the boiler. When the boiler requires water, the pump switches on pumping water from the receiver into the boiler. The receiver tank also contains an internal make-up water valve actuated by a stainless steel float. If the amount of condensate being returned to the receiver tank is inadequate to supply the boiler, additional make-up water is added to the receiver tank. This condition may occur when more steam is being produced than condensate being returned; common at system start-up. An overflow pipe is used to dump excess condensate to drain during times when less boiler feed water is required than the amount of condensate being returned. Larger boiler feed tanks may be advantageous to keep systems in balance.

The Boiler Feed Pumps (W4100 series) are equipped with Cast Iron bodies and Bronze Impellers. The pump receiver tank is made of Carbon Steel and available in Simplex or Duplex configurations.
