This in-line circulator has 3" suction and discharge connections paired with a 6.15" nominal diameter impeller. The pump uses stainless steel construction for the casing, impeller, face plate, and shaft, while the supporting bracket is cast iron. A replaceable cartridge bearing assembly isolates internal bearings from system fluids for application in heated or chilled water circulation up to 250°F. This unit includes a standard mechanical seal with a ceramic seat, carbon rotor, and EPT rubber. The hydraulic assembly has a dynamically and hydraulically balanced impeller combined with a rugged flexible rubber drive coupling to manage angular and parallel misalignment.
The resilient-mounted 1 HP motor operates at 1750 RPM and has an ODP enclosure for 115/208-230V, 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.
