Grundfos Hydro SOLO-E CRIE32 Variable Speed Pressure Booster Set (Max 750LPM) - Three Phase 

The Grundfos Hydro SOLO-E CRIE 32 is a fully integrated, single-pump variable speed booster system designed to deliver constant pressure and high energy efficiency for a wide range of commercial, light industrial and agricultural applications.

This stand-alone plug-and-pump solution combines a premium Grundfos CRIE vertical multistage pump with IE5 motor technology and an intelligent variable speed drive, maintaining precise system pressure regardless of demand changes — all while minimising energy use and water hammer.

Constructed from robust, corrosion-resistant stainless steel, the Hydro SOLO-E CRIE 32 includes a stainless steel outlet manifold, isolation and non-return valves, a Grundfos steel pressure tank, discharge pressure transmitter, and integrated pressure gauge — all pre-mounted on a sturdy 304 stainless steel base plate for quick, hassle-free installation.

Pre-programmed factory functions, flow estimation, and an easy-to-use interface ensure reliable day-to-day performance with minimal setup and maintenance. Whether boosting water supply for apartment buildings, schools, hotels, offices, or industrial wash systems, the Hydro SOLO-E CRIE 32 is a sustainable, low-maintenance booster that delivers constant pressure and significant energy savings over its long lifetime.
