This in-line pump has a cast iron casing and bracket with a bronze face plate. It includes a 4.75" nominal diameter stainless steel impeller and a stainless steel shaft. The suction and discharge ports measure 1 1/2". A replaceable bearing cartridge assembly holds the rotating components and isolates the bearings from system fluid temperatures. The mechanical seal assembly consists of a Silicon Carbide stationary seat, a carbon rotating element, and Viton elastomers, which handle operating temperatures up to 250°F. The standardized cartridge arrangement simplifies maintenance requirements for the unit.
The pump accepts a 1/2 HP motor in a 48 frame size. 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.
