Grundfos Hydro Solo-E Optimum Pressure Boosting System
The Grundfos Hydro Solo-E Optimum range brings substantially more than an efficient pump with additional equipment to pressure-boosting applications. You get a fully-optimised package with constant pressure control, flow estimation, and plug-and-pump installation for immediate, always-optimised operation. The graphical display built into the pump provides a real-time overview of booster set performance, delivering technology, efficiency, and ease-of-use in one complete package. Quite simply, the delivery of a single, optimised package means a more efficient solution than combining elements yourself—avoiding oversized pumps or systems that are expensive to maintain over their lifetime.
As an authorized Grundfos Water Pump Dealer in Dubai, we supply the complete Hydro Solo-E Optimum range with genuine warranty and technical support across the UAE.
