Sterling 4224GDF - 1/3HP 36 GAL 1PH Cast Iron Duplex Boiler Feed Pump

The Sterling 4200 G Series boiler feed pumps are designed to collect return condensate from low pressure steam boiler systems 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 4224GDF has a 3/4" connection and a 1/3 HP, 3450 RPM, 115v single phase motor. The 4224GDF is a duplex unit, with a 36 gallon tank, capable of pumping 6 gallons per minute at 20 psi and 30 BHP. Additional voltages are available, please contact us for price and availability.
