Boiler Feed Pumps Used (W4300 series - stainless 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.

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.
