This in-line pump has a cast iron casing and bracket paired with a stainless steel impeller and shaft. The unit includes 1 1/2" suction and discharge connections. A replaceable bearing cartridge assembly isolates the permanently sealed, grease-lubricated ball bearings from system fluid temperatures reaching 250°F. The hydraulic section includes a mechanical seal assembly with a ceramic seat, carbon mating ring, and EPT elastomers. This standardized cartridge construction simplifies maintenance and allows common service components throughout the assembly.
The assembly arrives less motor, but includes the 133-031 motor bracket for field installation. 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.
