Variable-speed retrofit for single-speed pool pumps — meets current energy codes. Programming is application-specific; tell us the pump and we'll set it up.
Lifecycle: two distributors list the ECM16SQU as discontinued. The compliant replacement is the EVQ165 — or the US Motors Neptune NPTQ165. This page is kept for reference and replacement matching.
Not CA/NY Title 20 compliant per InyoPools — the EVQ165 is the compliant option.
Confirming the right replacement
Before we quote, compare these fields on your failed motor'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 any suffix letters
- HP, RPM, and voltage
- Frame size (e.g. 284T) and enclosure (TEFC, ODP, etc.)
- Full-load amps
