This in-line circulator has 2-1/2" suction and discharge connections paired with a 4.30" nominal diameter impeller. The pump uses stainless steel construction for the casing, impeller, face plate, and shaft, while the support bracket is cast iron. The internal assembly includes a ball bearing cartridge and a mechanical seal composed of a carbon rotor and ceramic seat with EPT rubber, rated for liquid temperatures up to 250°F. A rugged flexible rubber drive coupling connects the motor to the pump to absorb misalignment. This configuration can be installed for heated or chilled water circulation, zoning large installations, and primary-secondary loops.
The 1/4 HP, 1750 RPM ODP motor operates on 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.
