Controlador de bomba Einhell 4174230, preto, diâmetro da mangueira 3,33 cm

Einhell 4174230 pump controller is an inline accessory designed to convert compatible water pumps into an automatic domestic water system. Finished in black, the unit monitors flow and pressure to control pump start/stop cycles. It fits hoses with a 3.33 cm diameter and is intended for use with garden pumps where automatic switching, dry-run protection and basic pressure regulation are required. The device includes an electrical socket for the pump and a 1.45-metre mains cable for connection to power.

Advantages

The controller provides automatic on/off operation based on pressure and flow conditions, reducing the need for manual intervention. Integrated dry-run protection helps prevent damage to the pump when no water is present, while the built-in non-return valve maintains system pressure and avoids backflow. The compact inline design allows straightforward retrofitting to existing pump installations and the included connection adapter simplifies assembly.

Suitable for

• Automatic garden irrigation systems
• Rainwater harvesting and household water reuse
• Domestic water transfer from tanks or wells
• Retrofit of compatible garden pumps to enable automatic control

Key specifications

• Color: black
• Hose/connection diameter: 3.33 cm
• Integrated mains cable length: 1.45 m
• Maximum working pressure: 10 bar
• Features: electronic flow/pressure switch, dry-run protection, non-return valve, pump socket

How to use

Install the Einhell pump controller inline between the pump and the system piping using the supplied connection adapter, ensuring the hose diameter matches 3.33 cm. Connect the pump into the controller's socket and plug the controller's mains cable into a suitable power outlet. When a tap or outlet is opened and pressure in the line drops, the electronic controller will automatically start the pump; when the outlet is closed and pressure rises, the controller will stop the pump. Observe local electrical safety rules and isolate power before any installation or maintenance.

Recommendations

For reliable operation, use the controller only with compatible garden pumps and piping that match the specified hose diameter and working pressure. Protect the unit from freezing temperatures and ensure electrical connections are made by a qualified person where required by local regulations.
