This in-line circulator has a 3" suction and discharge. The casing and bracket use cast iron construction, while the 6.15" nominal diameter impeller and shaft are stainless steel. The assembly includes a replaceable cartridge bearing design that isolates internal bearings from system fluid temperatures, allowing operation up to 250°F. This unit is equipped with a standard mechanical seal consisting of a carbon rotor and ceramic seat with EPT rubber. To manage misalignment, the pump uses a rugged flexible rubber drive coupling. The balanced impeller works within the cast iron casing for heated or chilled water circulation.
The pump has a 1 HP, 1750 RPM ODP motor for 115/208-230V and 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.
