MCI 4 AUTO - multistage pump with inverter
MCI 4 AUTO is a stainless-steel multistage surface pump equipped with a high-efficiency inverter. It maintains constant pressure in the system regardless of current water demand, adjusting the motor speed to match consumption. Thanks to inverter operation, a constant-pressure water supply system can save up to 60% energy compared with a system without an inverter. The pump delivers up to 115 l/min and has a maximum delivery head of 54 m.
Who it’s for
- Owners of single-family homes and larger properties – steady water pressure throughout an extensive system, even at high delivery heads.
- Residents in elevated areas – effectively boosts low water pressure from the mains.
- Installers – one-button operation, with no need to select separate automation equipment, clear specifications and manufacturer support.
- Gardeners with automatic irrigation systems – supply irrigation systems with water from a well or rainwater tank.
- Those investing in durability – fully stainless-steel AISI 304 hydraulics designed to withstand long-term use.
Applications
The MCI 4 AUTO pump is ideal for domestic and residential water systems: it draws raw water from a private well or boosts low water pressure from the mains, maintaining a steady flow. With a maximum delivery head of 54 m and an operating pressure of up to 10 bar, it is suitable for extensive systems and upgrades to home water installations. The pump does not treat water. If water from a private well is to be used for drinking, it must be appropriately treated and its quality monitored.
The unit can also be used to irrigate a garden with rainwater drawn from a tank and to supply smaller buildings with water. The MCI 4 AUTO 230 V pressure-boosting pump works with standard systems found in Polish single-family homes.
MCI 4 AUTO features
MCI 4 AUTO is a pump with a built-in inverter that smoothly adjusts the motor speed and maintains the set pressure regardless of how many outlets are open. The soft-start and gentle-stop function eliminates water hammer, while the lower average rotational speed reduces shaft wear and extends the unit’s service life. W To ensure smooth operation, the pump is equipped with a diaphragm pressure tank and a check valve.
The controller provides comprehensive protection: overcurrent, surge, undervoltage and short-circuit protection, rotor lock protection, and dry-running protection without the need to install probes or sensors in the well. Operation is as simple as setting the working pressure with a button. The pump runs quietly, making it suitable for installation in living spaces.
The entire construction is made of AISI 304 stainless steel – housing, impellers, diffusers and covers, intermediate wall, shaft, motor rotor, and ports. The mechanical seal uses a SIC/SIC/EPDM configuration, and the pump is driven by a closed-construction asynchronous squirrel-cage motor in an aluminum housing with external ventilation.

Frequently asked questions (FAQ) – What is the MCI 4 AUTO pump used for?
What is the MCI 4 AUTO pump used for?
The MCI 4 AUTO is a complete solution for drawing and pumping untreated water from a private well in homes and on properties, as well as for boosting water pressure when the pressure in the mains supply is too low. Thanks to its built-in inverter, it maintains constant pressure at every outlet, with an operating pressure of up to 10 bar.
How does a pump with an inverter differ from a conventional pressure booster system?
Instead of cycling on and off, the pump smoothly adjusts the motor speed to match the current water demand. This results in constant pressure, smooth starts, quieter operation, and energy savings of up to 60% compared with a system without an inverter.
Can the MCI 4 AUTO be used to water a garden with rainwater from a tank?
Yes, the pump can draw water from a rainwater tank or well to supply an irrigation system. When drawing water from an open water source, a check valve must be installed on the suction pipe to prevent the pipe from draining on its own. You can find the appropriate components in our accessories for surface pumps and pressure booster systems.
How is the pump protected against dry running?
The MCI 4 AUTO has built-in dry-run protection managed by its controller, with no need to install probes or sensors in the well. It also has overcurrent, surge, undervoltage, and short-circuit protection, as well as protection against impeller blockage.
Where can I buy the MCI 4 AUTO pump?
As a manufacturer, we do not sell directly to customers. The MCI 4 AUTO pump is available from our retail partners, plumbing wholesalers, and authorized online distributors.
What warranty does the MCI 4 AUTO pump come with?
The IBO MCI 4 AUTO pump comes with a 24-month (2-year) manufacturer's warranty.
