Automatic pressure maintenance station CB2-MKm8-4-N

The CB2-MKm8-4-N is an automatic pressure-boosting station based on two Pedrollo MKm 8-4 pumps, operating on a 230 V single-phase power supply. It is ideally suited for private homes, agricultural facilities, and small commercial buildings where reliable clean water supply is required under variable demand and unstable pressure conditions.

Key Features:

▪️MKm 8-4 Pumps: High-efficiency single-phase multistage pumps that offer an excellent balance of performance and energy efficiency. Provide stable pressure even under high point-of-use demand.

▪️Single-phase power supply (230 V): Simplifies installation in areas without access to a three-phase network.

▪️Compact and versatile: Vertical assembly minimizes footprint, allowing installation in tight technical spaces.

▪️Industrial-grade design: Includes inlet and outlet manifolds, ball valves, check valves, and a durable metal base.

▪️Control panel:

automatic pump alternation;

anti-cycling protection;

ammeter protection;

integrated logic for smooth system operation.

Operating Principle:

The CB2-MKm8-4-N operates using adaptive activation: when system pressure drops, one pump starts; if demand increases, the second is engaged. The station automatically determines how many pumps are needed to reach the required pressure. Thanks to the electronic panel, the system runs without user intervention, with automatic protection against overheating and dry running.

Applications:

▪️Water supply for private and country homes;
▪️Irrigation and drip watering systems;
▪️Single-phase powered facilities: cafés, workshops, laundries;
▪️Greenhouses and agricultural sites;
▪️Automation of water treatment systems;
▪️Pumping stations for water supply from tanks and wells.

The Pedrollo CB2-MKm8-4-N is a compact, energy-efficient, and fully automated solution for locations with limited power supply that require stable water pressure. With its robust construction, intelligent control, and installation versatility, the station is perfectly suited for both residential use and small business applications.
