The Series 100 3-piece design (bearing assembly, seal, motor) has been the industry standard for decades — every wearing part is field-serviceable. Always include the part number (106189, 106197LF, 106190, 106192LF) when quoting.
Confirming the right replacement
Before we quote, compare these fields on your failed pump's nameplate. If any of them differ, send us a photo of the nameplate and we'll match it exactly rather than guessing:
- Full model number — including the part number (e.g. B&G P/N) where one exists
- Voltage and phase
- System duty: flow (GPM), head (ft), and fluid — heating water vs. potable water matters
- Flange size and orientation for in-line replacements
