IBO KBFU AUTO 50-1.5 sludge pump with agitator, 400 V
The KBFU AUTO 50-1.5 is a three-phase automatic sludge pump with a power rating of 1.5 kW and a 400 V supply. It is equipped with a chromium-alloy agitator and a built-in control system with a level sensor. The KBFU AUTO series is designed for unattended operation in collection wells and pumping stations—the pump starts and stops automatically according to the liquid level, with no need for manual operation.
Who it's for
-
Investors and building managers with collection wells – The built-in level sensor and controller eliminate the need for manual supervision, allowing the pump to operate fully automatically around the clock.
-
Construction companies carrying out long-term drainage work – Automatic activation based on the water level eliminates the need to assign an employee to operate the pump on the construction site.
-
Mines and extraction plants – The chromium-alloy agitator and ability to handle particles up to 10 mm ensure reliable operation with thicker sludge than standard KBFU models.
-
Drainage system installers – Built-in automation simplifies system design, while the DN 2" connection, which can be positioned vertically or horizontally, offers installation flexibility.
-
Municipal utilities with pumping stations – Automatic operation and no need for constant supervision reduce operating costs when groundwater flows in continuously.
Applications
The KBFU AUTO series builds on the standard KBFU series with an agitator, a control system with a level sensor, and a double mechanical seal. These features make the pump suitable for use in collection wells and pumping stations, where it must respond automatically to changing liquid levels without operator intervention. The chromium-alloy agitator actively breaks up sediment at the inlet, allowing the pump to handle slurry containing particles up to 10 mm—twice as large as those handled by standard models in the series.
A key feature of the design is the cooling jacket surrounding the motor. Thanks to this, the pump does not need to be fully submerged in the pumped medium to maintain a safe operating temperature—the motor is cooled through the jacket wall even when the liquid level in the tank is already very low. The control system and thermal protection in the motor winding provide additional protection during extended unattended operation.

Frequently asked questions (FAQ) – KBFU AUTO 50-1.5 sludge pump
How does the KBFU AUTO differ from the regular KBFU series?
The AUTO series has three components not found in the standard KBFU series: a liquid level sensor that controls the pump’s automatic start and stop, a chrome alloy agitator that stirs sediment at the inlet, and a control system. A double mechanical seal is also used. W practice: you put the pump in the sump, connect the power supply, and it manages its operation by itself.
Why is a level sensor better than a float switch?
A conventional float switch is a mechanical component with moving parts, vulnerable to cable tangling, clogging from sediment, mechanical damage, and the effects of the medium’s pH level. The level sensor used in the KBFU AUTO series has a sealed, watertight design with no external moving parts. It is more resistant to challenging operating conditions in sludge and acidic environments, and requires no extra space in the sump.
How can I protect the pump from oversized particles and stones?
The pump itself has perforations at the inlet, which act as the first barrier against larger particles. When operating in environments with stones or coarse rubble, it is worth using a submersible pump basket as well – a metal cover resembling a basket with small perforations that fits directly over the pump and effectively filters whatever enters the inlet. Alternatively, a protective mesh with openings smaller than 10 mm secured around the pump works well. Both solutions are inexpensive, easy to install, and significantly extend the device’s service life when operating in contaminated areas.
Where can I buy the IBO KBFU AUTO 50-1.5 pump?
The pump is available from Dambat’s sales partners, plumbing wholesalers, and specialist technical stores. Dambat does not sell directly.
