This in-line circulator uses cast iron construction for the casing and bracket, while the 4.90" nominal diameter impeller and shaft use stainless steel. The unit includes a ball bearing cartridge assembly and is equipped with a mechanical seal consisting of a carbon rotor, ceramic seat, and EPT rubber. This configuration handles fluids up to 250°F through 3" suction and discharge connections. The hydraulically balanced impeller and shaft sleeve protect internal components from high system temperatures while maintaining fluid movement in heated or chilled water systems.
The pump has a 1/2 HP, 1750 RPM, ODP motor configured for 115/230V 1PH power. 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.
