Automatic pressure maintenance station CB2-MKm3-4-N.

A reliable solution for stable water supply in private and commercial systems.
This automatic booster station is equipped with two vertical MKm 3-4 pumps and is designed to maintain water pressure within set limits, even under variable flow conditions.

The CB2-MKm3-4-N station operates fully automatically and can run either one pump or both at once, depending on demand. Switching between pumps is handled automatically by the built-in electronic control unit based on load. This ensures uninterrupted water delivery and an even load distribution between pumps, extending their service life.

The unit is mounted on a sturdy metal frame and includes suction and discharge headers, ball valves, check valves, two pressure switches, and a pressure gauge. The single-phase MKm 3-4 pumps feature:

▪️ High energy efficiency
▪️ Low noise levels
▪️ Resistance to voltage fluctuations

Motors run at 50 Hz and have built-in thermal protection to prevent overheating during continuous operation. The starting scheme eliminates backflow issues, preventing multiple starts during short water draws. Overload and undervoltage protection are also included.

This station is suitable for water supply in homes, hotels, and offices, as well as agricultural use—such as irrigation. It handles fresh water and chemically neutral fluids, delivering stable pressure even with unstable supply from the main line, tank, or well. Installation must be indoors or under shelter.

If you need a compact, quiet, and reliable booster station for stable pressure increase, Pedrollo CB2-MKm3-4-N is the optimal choice. It’s ideal for moderate water demands in private homes, vacation properties, farm buildings, cafés, and small commercial units. The station is easy to maintain, tailored to local conditions, and compatible with existing water systems.
