The Grundfos CM is a compact centrifugal water‑booster pump designed for freshwater domestic systems on vessels, featuring an easy‑replace cartridge seal and optional NSF food‑grade certification. As a Centrifugal Pump, it is normally installed in the engine room, pump room, cargo area or auxiliary machinery space within the service defined by the vessel piping arrangement. In that role, its primary purpose is to transfer liquid for the duty identified by the listed system. Centrifugal, screw, self-priming, progressive-cavity and service-specific pumps differ in hydraulic principle, suction behaviour and permissible media, so the exact construction must be confirmed from the installed documentation. Power: 3 kW; capacity: 3-25 m³/h @ 6 bar. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Free of charge — send us your request for Grundfos equipment. Our team checks it and replies by e-mail.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
