Grundfos UPSe 15-58FR is a high-efficiency cast iron ECM 115V circulator pump with integrated check valve and rotated flange, suitable for almost any hydronic (baseboard/radiator/fan coil), radiant floor heating and cooling application.
This model is an improved version of Grundfos's flagship UPS15-58FR model, boasting a significantly improved efficiency and (9) modes (3x constant speed/curve, 3x constant pressure and 3x proportional pressure) instead of (3) constant speeds.

- One-button operation with (9) operating modes to choose from: (3) constant pressure curves (the head across each zone is constant), (3) proportional pressure curves (the head pressure is reduced at falling heat demand and conversely), and (3) constant curve
- High-efficiency ECM motor uses up to 85% less electricity
- Built-in removable check valve
- Dry-run protection stops the circulator if water is not detected in the system
