This in-line circulator has 3" suction and discharge connections paired with a 6.15" nominal diameter impeller. The pump uses stainless steel construction for the casing, impeller, face plate, and shaft, while the support bracket is cast iron. A replaceable cartridge bearing assembly isolates the internal bearings from system fluid temperatures. The mechanical seal consists of a ceramic seat, carbon rotor, and EPT rubber, allowing the unit to handle system fluids up to 250°F. The enclosed impeller is dynamically and hydraulically balanced for stable operation in heated or chilled water applications.
The 1 HP, 1750 RPM open-drip proof (ODP) motor operates on a 230/460V, 3PH 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.
