| Duty | ECM end-suction — Xylem's current ECM answer to e-90 replacements |
Per the Xylem e-90ECM sell sheet (1/2026). HP-to-P/N mapping is inferred from the sell sheet's weight groups — send the P/N off your pump tag and we will quote the exact unit.
Replacing a fixed-speed e-90? See the BE9021S and BE9023S.
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 e-90ECM 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.
