This in-line circulator has 3" suction and discharge connections paired with a 4.90" nominal diameter impeller. The pump uses stainless steel construction for the casing, impeller, face plate, and shaft, while the support bracket is cast iron. A replaceable cartridge bearing assembly isolates internal bearings from system fluid temperatures up to 250°F. The unit includes a mechanical seal built with a carbon rotor, ceramic seat, and EPT rubber. This configuration is suitable for application in heated or chilled water circulation, primary-secondary loops, and fresh water service.
The 1/2 HP motor operates at 1750 RPM within an ODP enclosure using a 230/460V, 3PH 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.
