This in-line circulator has a 3" suction and discharge configuration combined with a 4.30" nominal diameter impeller. The casing, impeller, face plate, and shaft use stainless steel construction, while the bracket is cast iron. This unit includes a replaceable cartridge bearing assembly and a mechanical seal built with a carbon rotor, ceramic seat, and EPT rubber. This seal selection is rated for fluid temperatures up to 250°F. The cartridge design isolates the bearings from system temperatures, making the pump suitable for chilled or heated water circulation and fresh water service.
The 1/4 HP motor operates at 1750 RPM with an open-drip proof (ODP) enclosure and 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.
