Product Overview
Boiler Feed Pumps Used (W4200 series - cast iron 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.
Features
• Fabricated steel receivers (W4100), Cast Iron (W4200), Stainless Steel (W4300)
• Simplex and duplex packages
• Bronze-fitted centrifugal pumps
• Energy-efficient 3450 RPM motors
• Automatic venting of mechanical seal
• Ceramic pump seal with carbon face
• Heavy-duty float switch
• All steel and iron receivers over 24 gallons include a threaded NPT overflow port
How It Works
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.
Selection / Sizing / Capacities
• For a Boiler Feed Pump, 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. This is used if the amount of condensate being returned to the receiver tank is inadequate.
• On Duplex boiler feed pumps, an Electric Alternator is required to cycle operation between the two pumps.
• The capacity of the boiler feed pump in Gallons Per Minute (GPM) is based on the Boiler horsepower (hp).

For Example: A 15 horsepower boiler will produce up to 500 lbs/hr of steam when running at maximum load which translates to requiring 1.0 GPM of water make-up to the boiler. Using a 3:1 safety factor would require a 3.0 GPM Boiler Feed pump. The recommended receiver sizes based on boiler horsepower are shown in selection chart.

• Select a discharge pressure for the pump to overcome boiler pressure and all system back pressure including frictional piping losses. Pump discharge pressures of 20-50 PSI are available.
