Carbon Steel Boiler Feed Pumps

Category: Tags: , , ,

Boiler Feed Pumps Used (W4100 series – carbon steel receivers) 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, additional boiler feed water is automatically added to the receiver tank.

SIMPLEX & DUPLEX – Water Level Control System on boiler is used to activate the pump.
SIMPLEX & DUPLEX – Automatic Make-up Water Valve is activated by a level float that adds additional boiler feed water to the receiver tank if required.

Description

Carbon Steel 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.

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.
