Automatic pressure maintenance station CB2-MK3-6-N

Industrial pumping station with two high-performance three-phase pumps for stable pressure in large-scale water supply systems. The CB2-MK3-6-N model is designed for reliable and uninterrupted operation in facilities with high demands for water pressure performance and stability.

The station is equipped with two vertical three-phase Pedrollo MK 3-6 pumps, each designed for long-term intensive operation. The electronic control system provides automatic pump regulation: they operate alternately under normal load and simultaneously during peak water consumption. This ensures even equipment wear, energy savings, and consistent water supply regardless of pressure fluctuations in the system.

Structurally, the station is a monoblock unit mounted on a durable metal frame, and includes:

▪️discharge and suction manifolds,
▪️check valves and ball valves,
▪️two pressure switches and a pressure gauge,
▪️an intelligent control unit with overload and undervoltage protection, as well as anti-cycling (anti-bounce) start system.

The pumps connect to a three-phase power supply (230/400 V), operate at 50 Hz, and offer high efficiency with strong protection against external factors: insulation class F, protection rating IP44. They are suitable for pumping clean, chemically neutral water and are designed for continuous S1 operation.

Recommended areas of application:

▪️multi-story residential complexes, homeowners’ associations, administrative buildings;
▪️industrial enterprises, logistics and warehouse facilities;
▪️centralized second-stage pumping stations;
▪️irrigation, filtration, and cooling systems in the agricultural and industrial sectors.

The station should be installed in dry technical rooms with access for maintenance. All components are certified and designed for long service life under intensive operation.

The Pedrollo CB2-MK3-6-N is a powerful, intelligently controlled, and industrial-grade pressure station capable of ensuring stable water supply for the most demanding facilities. It is an ideal solution for large water consumers where not only performance but also the reliability of every component is crucial. A choice for those who prioritize flawless water supply system operation.
