KBFU-AUTO-50-0.48 – sludge pump
The IBO KBFU-AUTO-50-0.48 submersible pump features a built-in intelligent controller with a liquid-level probe, enabling fully automatic and virtually maintenance-free operation. Its design with a cooling jacket and wide impeller clearance allows it to operate in water containing sand and sediment without requiring the device to be fully submerged.
Who is it for?
- Construction companies – dewatering excavations and foundation pits without the need for constant water-level monitoring.
- Property and landowners – automatic emptying of soakaway pits and rainwater tanks.
- Installers – the compact design enables installation in wells and underground spaces with a small diameter.
- Service and equipment rental companies – the low weight and simple operation make transportation and quick commissioning at successive sites easier.
Applications
The pump is suitable for dewatering construction excavations, wells, various utility pits, and underground spaces. It also performs well when draining rainwater, muddy water, and slightly contaminated water where the liquid level changes irregularly.
The automatic level probe with adjustable activation height eliminates the need for manual monitoring of the device, while delayed shutdown at a low water level prevents the pump from switching on too frequently due to natural fluctuations in the liquid level. The KBFU-AUTO-50-0.48 230 V submersible pump operates on a single-phase power supply, making it easy to connect at a typical construction site.
Features
The pump controller is responsible not only for automatic switching on and off based on the liquid level, but also for motor protection – in the event of an incorrect supply voltage or a blocked impeller, the device shuts down automatically and resumes operation once conditions have stabilised. Water is drawn in from below and flows along the motor housing and water jacket, ensuring effective cooling and enabling continuous operation even when the pump is not fully submerged.
The semi-open impeller, positioned away from the pump body, reduces the risk of clogging with sediment or sand, while the cast-iron hydraulic components together with the AISI 420 stainless steel shaft provide corrosion resistance and a long service life in a damp operating environment. The threaded discharge outlet can be installed vertically or at an angle, making it easier to route the hose without kinking it in confined wells.

Frequently asked questions
What is the KBFU-AUTO-50-0.48 pump used for?
The KBFU-AUTO-50-0.48 pump is used for dewatering construction excavations, wells, utility pits, and draining rainwater, muddy water, and slightly contaminated water.
How does the KBFU-AUTO-50-0.48 differ from a standard pump in the KBFU series?
Unlike the standard KBFU version, the AUTO model is equipped with a controller and liquid-level probe, allowing it to switch on and off automatically depending on the water level, without manual operation.
Will the KBFU-AUTO-50-0.48 pump work in my well or excavation?
The compact design allows installation in wells and underground spaces with a small diameter, while the wide impeller clearance tolerates the presence of sand and fine sediment in the pumped water. If you need help selecting the right device for your installation, please contact our technical department
How does the automatic water-level sensor in the KBFU-AUTO pump work?
The pump operates as long as the level probe is submerged in water, and switches off with a delay of approximately 60 seconds once the probe is exposed. This prevents overly frequent activation when the liquid level fluctuates. The probe height can be adjusted according to the installation requirements.
Where can I buy the KBFU-AUTO-50-0.48 pump?
The pump is available from our commercial partners, plumbing and installation wholesalers, and authorised online distributors.
What warranty applies to the KBFU-AUTO-50-0.48 pump?
The IBO pump is covered by a 24-month manufacturer’s warranty, while warranty and post-warranty service is provided by Dambat.
