Sterling 4124GDF - 1/3HP 30 GAL 3PH Steel Duplex Boiler Feed Pump

This item is obsolete. It is shown for reference purposes only. A compatible replacement is shown in the Alternate Items tab below.
The Sterling 4100 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 3/16" receiver tank with a standard gauge glass assembly and feature automatic venting. The centrifugal pumps are bronze-fitted with a "SterlSeal" ceramic seal. The 4124GDF has a 3/4" connection and a 1/3 HP, 3450 RPM, 208-230/460v three phase motor. The 4124GDF is a duplex unit, with a 30 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.
