Automatic pressure maintenance station CB2-2CPm25-130N

The CB2-2CPm25-130N is a fully assembled and ready-to-use automatic pressure-boosting station based on two single-phase Pedrollo CPm 25/130 pumps. This station is designed to supply clean water and chemically neutral liquids, enhancing pressure in residential, municipal, and commercial water supply systems. It is suitable for use in private homes, hotels, public buildings, as well as irrigation and filtration systems.

Design Features:

▪️CPm 25/130 Pumps:
Reliable single-phase centrifugal electric pumps, well-balanced for flow and pressure. They provide stable performance with moderate energy consumption.

▪️Metal Frame:
Ensures the stability of the entire unit, reduces vibrations, and protects against corrosion.

▪️Hydraulic Piping Assembly:
Includes suction and discharge manifolds, check valves, and ball valves — all pre-installed and ready for connection.

▪️Control System:
The QE2M electric control panel is equipped with:

pump alternation function (for balanced wear);

protection against overheating and overload;

low-voltage control circuit;

panel door lock;

anti-cycling system to prevent false activations from minor flow fluctuations.

▪️Pressure Gauge and Two Pressure Switches:
Mounted on the discharge manifold and adjustable by the user depending on system requirements (factory settings are based on average operating conditions).

Operating Principle:

The station operates automatically: when system pressure drops, one pump starts; if water demand increases, the second pump is activated. The electronic control logic automatically determines the optimal number of pumps to run, ensuring efficient water delivery and energy savings.

Applications:

▪️Water supply for cottages, summer homes, and private residences;
▪️Pressure boosting in hotels, resorts, and offices;
▪️Drip and micro-irrigation systems;
▪️Swimming pools and water purification stations;
▪️Laundries, car washes, cafés, and other facilities with variable water usage.

CB2-2CPm25-130N is a compact, reliable, and energy-efficient solution for stable water supply. The system is easy to install, fully automated, and requires no constant supervision. Ideal for sites where consistent pressure without drops or interruptions is essential.
