Sterling 4100 Series condensate 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 condensate units have a 3/16" steel receiver tank with a standard gauge glass assembly and feature automatic venting.
The centrifugal pump is bronze-fitted with a "SterlSeal" ceramic seal.
The 4128G has a 3/4" connection and a 1/3 HP, 3450 RPM, 115-230v single phase motor.
The 4128G is a simplex unit, with a 15 gallon tank, capable of pumping 12 gallons per minute at 20 psi and 8,000 EDR.
Additional voltages are available, please contact us for price and availability.
