The 4300 Series stainless steel condensate and boiler feed pumps are available in simplex or duplex construction. The heavy-duty, ball-bearing, close-coupled 3,450-rpm motor has a stainless steel shaft. Boiler feed pumps are controlled by a water level controller mounted on the boiler. If condensate is lost or delayed in the system, it is automatically replaced in the heavy-gauge 3/16-inch stainless steel receiver through the make-up water valve. All receivers 45 gallons in size and larger are supplied in duplex design, with one pump opening covered when a simplex design is specified. Features include bronze-fitted centrifugal pumps, automatic venting, a heavy-duty float switch, and Sterl-Seal ceramic pump seal.
