This in-line circulator has 3" suction and discharge connections paired with a 4.90" nominal impeller. The unit uses stainless steel construction for the casing, impeller, face plate, and shaft, while the bracket is cast iron. A replaceable cartridge bearing assembly isolates the internal bearings from system fluid temperatures up to 250°F. This assembly includes a mechanical seal consisting of a carbon rotor, ceramic seat, and EPT rubber. The enclosed impeller is dynamically and hydraulically balanced, combined with a rugged flexible rubber drive coupling to absorb angular and parallel misalignment.
The unit includes a 1/2 HP, 1750 RPM ODP motor for 115/230V, 1PH power supplies. 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.
