This in-line pump uses a replaceable bearing cartridge assembly that isolates the bearings from system fluid temperatures. The unit includes a Type 21 mechanical seal, which consists of a ceramic seat, carbon mating ring, EPT elastomers, and stainless steel spring and retainer components. The construction has a standardized cartridge and seal arrangement to simplify long-term maintenance requirements. This assembly uses a cooler-running design to maintain thermal stability during operation.
The unit has a 0.5 HP, 1750 RPM motor with an ODP enclosure, configured for 115/230V, 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.
