Description
Variable speed, wet-rotor ECM pump for closed-loop hydronic systems
The Honeywell/Resideo AquaPUMP PCVF-ECM2020 automatically adjusts its speed to match system demand, so radiators and in-floor loops get steady comfort without constant tinkering. It can run in “auto-adapt” mode or on fixed pressure/speed curves, and it installs like a standard 2-bolt flange circulator with a front-facing control panel for quick setup.
Stainless-steel version available for open/potable loops
What it Does Well
Auto-Adjusts to the Load
“Auto” mode learns your system and varies pump speed on its own. You can also select constant-pressure or proportional-pressure curves, or lock in a fixed speed.
Covers Common Hydronic Layouts
Suited for underfloor heating, one-pipe/series, two-pipe/parallel, and multi-zone systems.
ECM Efficiency
Electronically commutated motor with built-in logic delivers high efficiency and quiet operation.
Simple to Install
Non-submersible, dry-location pump with a front control panel and wiring box. Same flange pattern you’re used to.
Cast-Iron Body
Cast iron for closed loops.
