This in-line circulator has 2-1/2" suction and discharge connections with matching companion flanges paired with a 4.30" nominal stainless steel impeller. The casing and bracket use cast iron construction, while the shaft and impeller use stainless steel. This unit includes a replaceable cartridge bearing assembly that isolates internal bearings from system fluid temperatures up to 250°F. For sealing, the pump has a mechanical assembly with a ceramic seat, carbon rotor, and EPT rubber. A flexible rubber drive coupling connects the motor to the pump to handle parallel and angular misalignment.
The 1/4 HP motor operates at 1750 RPM within an ODP enclosure and uses 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.
