UPS4 GO is a high-efficiency circulator pump fitted with an electronically commutated motor and designed for circulating liquids in heating and air conditioning systems.UPS4 GO is equipped with intelligent controls and offers three control modes: constant pressure, proportional pressure and constant curve. Each mode has three adjustable speed settings.Replacement of older integrated and stand-alone circulator pumps, including replicating curves, is made easy by using the Grundfos GO app and operating panel.The toolless installer plug enables a fast and easy electrical connection.The automatic self-venting ability and dry-running protection ensure quiet operation and reliability of the pump.The product features robust startup which reduces the risk of blockages from dirt, magnetite and limescale build-up. In the unlikely case of a blocked pump, the motor continuously attempts to start at the highest possible torque, ensuring startup in tough conditions.The ceramic shaft and bearings experience minimal wear, resulting in a longer lifespan and a reduced likelihood of noise in the system due to increased bearing clearance from wear.Fault finding is fast and easy by using the error codes on the pump operating panel.

Main product features:

• High-efficiency EC motor: Reduces power consumption.
• Toolless installer plug: Quick and easy electrical connection.
• Grundfos GO app compatibility: Simplifies setup, mode selection, and curve replication for replacing older pumps.
• Dry-running protection: Prevents pump damage during startup without water.
• Robust startup: Overcomes potential blockages from dirt, limescale, or magnetite.
• Self-cleaning motor behavior: Repeated high-torque startup attempts for reliability.
• Ceramic shaft & bearings: Low wear, extended lifespan, and reduced noise over time.
• Integrated fault diagnostics: Clear error codes on the operating panel assist with fast troubleshooting.
• Retrofitting or replacing older integrated or stand-alone circulator pumps
• Residential or light commercial heating and cooling systems
