This in-line circulator uses stainless steel construction for the casing and impeller. The unit includes an alloy steel shaft with a cupro-nickel shaft sleeve. A replaceable cartridge bearing assembly isolates internal bearings from system fluid temperatures. The pump has a two-piece carbon and ceramic mechanical seal, while companion flanges are provided for installation into piping ranging from 3/4" to 1 1/2". The internal structure includes a dynamically and hydraulically balanced impeller. This pump can be installed in residential or light commercial chilled or heated water systems.
The motor operates at 1/12 HP and 1750 RPM, powered by a 115V 1PH supply. Maintenance-free operation is supported by permanently sealed, grease-lubricated motor ball bearings. Utilizing a rear pull-out design, the assembly permits complete removal of the motor and rotating components for servicing without disturbing the connected piping layout.
