One bearing cartridge services the whole line (removable). Factory order numbers are longer (e.g. 1619E3E3 = 2 HP 3-phase) — send the full number off your pump tag and we will quote the exact configuration.
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
Which 1600 Series do you have?
Send the exact model or part number off your nameplate. We'll confirm the match and quote it with availability and lead time.
