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.

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. Fault finding is fast and easy by using the error codes on the pump operating panel.

The New UPS3 supersedes the best-selling domestic circulator in the UK

Built on a platform proven in millions of boilers, the new UPS3
combines increased energy efficiency, an easier to wire plug and
on board diagnostics with stalwart features such as ceramic bearings
and shafts, a manual deblocking port and robust start-up functionality.

Plus, clever design means the new UPS3 can be used not only in system
installations but also inside many of the UK’s domestic boilers. Simply scan
the old pump with the new Grundfos GO Replace smartphone app and it will
tell you if the UPS3 is a compatible fit.

That gives you the chance to fix even integrated pump issues
in one visit, saving you time and your customer money.
