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.
