A Pump You Can Truly Rely On

On a commercial property, equipment that lets you down is not an option. From keeping offices warm to ensuring hot water in a hotel, reliability is everything. The Grundfos UP 40-50 F (product code: 52021295) is built to prevent that headache. It’s a fit-and-forget solution from a brand trusted by UK professionals.

As one of the most dependable commercial circulators available, its powerful UP40-50 3-phase head is designed for constant, efficient operation. The three speed settings give you the flexibility to tailor performance to your system's demands, preventing energy waste and reducing running costs. The clever canned-rotor design means the pump and motor are a single, sealed unit that runs so quietly you'll barely notice it.

With no shaft seal and liquid-lubricated bearings, it’s virtually maintenance-free, meaning no leaks, hassle, or costly call-outs. Installation is straightforward thanks to the standard DN 40 flanged connections and tough cast iron body. For a seamless setup, add the right flanges and pump valves from our accessories range. It’s designed to make your job easier from day one.

• Set Your Speed: The 3-speed motor lets you match performance to your system, saving energy and money.
