GRUNDFOS - CMBE MULTI-STAGE BOOSTER SYSTEMS CMBE 1-44 - Phase 1 0.75 200-240 - 98548109

The Grundfos CMBE 1-44 Booster System, MPN 98548109, is a compact variable-speed multistage pump engineered to maintain consistent water pressure in residential and light-commercial plumbing systems. Operating on single-phase 200–240V power, it combines a stainless steel centrifugal pump, high-efficiency permanent-magnet motor, integrated frequency converter, pressure sensor, diaphragm tank, pressure gauge and non-return valve in one preassembled package. The controller automatically adjusts motor speed as water demand changes, improving pressure stability and energy efficiency. It is ideal for municipal water boosting, storage tanks, irrigation, rainwater systems and other clean-water transfer applications.

Cross references: Grundfos 98548109; Grundfos CMBE 1-44, 1 × 200–240V; Grundfos 98810910, the corresponding 115V CMBE 1-44 configuration. The 115V and 200–240V versions are not direct electrical substitutes unless the site power supply is compatible.

Usage: The CMBE 1-44 is installed between a clean-water source and the building’s plumbing distribution system. Its pressure sensor detects changes in demand and signals the integrated speed controller to raise or lower motor speed, maintaining the selected discharge pressure as faucets, showers, appliances or irrigation zones open and close. The included diaphragm tank reduces unnecessary starts, while the non-return valve prevents reverse flow. Typical installations include municipal supply boosting, cisterns, break tanks, irrigation systems and light-commercial water supply.
