GRUNDFOS CMB 5-46 .9kw PRESSURE PUMP

Grundfos CMB 5-46 Booster Pump Set

The Grundfos CMB PM is a compact booster set designed for efficient water supply in domestic and light commercial applications. Paired with a Grundfos PM pressure manager, it automatically starts and stops the pump based on demand — delivering reliable, consistent water pressure without you having to think about it.

Set-and-Forget Pressure Control
The pressure manager monitors demand and controls the pump automatically, protecting it from dry running while keeping pressure steady throughout your home. Installation is straightforward — once connected to your pipework, it's simply a matter of plugging in and the system is operational.

Built to Last
Constructed with a 304 stainless steel body, impeller, and pump shaft, along with a technopolymer diffuser, the CMB 5-46 is built for durability in both mains and rainwater applications.

Higher Flow for Bigger Demands
With a robust multistage centrifugal pump design, the CMB 5-46 steps up flow capacity over the smaller CMB models — well suited to larger households or light commercial sites with multiple outlets running at once. Note it's not self-priming, with a max suction lift of 1m.
