This in-line circulator has 3" suction and discharge connections paired with a 4.40" nominal diameter impeller. The pump uses stainless steel construction for the casing, impeller, face plate, and shaft, while the bracket is cast iron. A replaceable cartridge bearing assembly isolates internal components from system fluid temperatures, allowing for operation up to 250°F. The sealing system includes a standard two-piece carbon and ceramic mechanical seal with EPT rubber. To manage angular and parallel misalignment, the unit is built with a rugged flexible rubber drive coupling between the motor and the pump assembly.
The motor has 1/3 HP and an operating speed of 1750 RPM within an ODP enclosure, requiring a 115V 1PH power 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.
