Sterling 4236JDF - 1/2HP 50 GAL 1PH Cast Iron Duplex Boiler Feed Pump

The Sterling 4200 J Series high capacity boiler feed pumps are designed to collect return condensate and return it to the boiler. Water levels are maintained by a mechanical make-up water valve with a heavy-duty float switch. The boiler feed pump is controlled by a boiler controller that senses the boiler water level and sends a signal to the pump for water. These Sterling boiler feed units have a heavy duty cast iron receiver tank with a standard gauge glass assembly and feature automatic venting. The centrifugal pumps are bronze-fitted with a "SterlSeal" ceramic seal. The 4236JDF has a 1-1/2" connection and a 1/2 HP, 3450 RPM, 115v single phase motor. The 4236JDF is a duplex unit, with a 50 gallon tank, capable of pumping 9 gallons per minute at 30 psi and 45 BHP. Additional voltages are available, please contact us for price and availability.
