The Hydro Multi-B, an all-variable-speed-controlled pump system, utilizes two to three Grundfos CME pumps and is designed to provide the greatest range of solutions for engineered packaged pumping systems. The Hydro Multi-B booster pump system has two key features: a CU323 controller for efficient, optimized pump control in constant-pressure applications; and simplicity of installation and operation — the key design concept for the system. Applications for the Multi-B include domestic water-pressure boosting, such as large homes, multistory buildings, apartment complexes, small hotels, rural areas requiring pressure boosting, and anywhere redundant pumping is required.
