This in-line circulator has 3" suction and discharge connections and includes a 4.90" nominal diameter impeller. The pump casing, impeller, face plate, and shaft use stainless steel construction, while the bracket is cast iron. It is built with a ball bearing cartridge assembly and a high-temperature mechanical seal. This seal has a Sealide-C silicon carbide stationary seat combined with a carbon rotating element and Viton elastomers rated for service up to 300°F. The internal rotating assembly is paired with a flexible rubber drive coupling to manage shaft misalignment.
The motor is a 1/2 HP, 1750 RPM ODP model configured for 200-230/460V, 3PH 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.
