IBO KBFU 50-1.5 230 V submersible slurry pump
The KBFU 50-1.5 is a single-phase slurry pump with a power rating of 1.5 kW, powered by 230 V and designed for intensive dewatering work requiring high performance without the need for a three-phase connection. The KBFU series is designed to operate in media containing sand, sludge, and abrasive particles—where standard centrifugal pumps quickly fail.
Who is it for?
-
Drainage and road construction contractors – a capacity of 420 l/min and a head of up to 18.5 enable efficient dewatering of extensive linear excavations.
-
Mines and extraction plants – the cast-iron body with a wear-resistant chromium-alloy coating handles intense abrasive contamination.
-
Installers and service teams – the 2" threaded outlet and cable with a plug shorten the time needed to start the pump at the failure site.
-
Facility managers and property administrators – high performance with household power is ideal for removing the effects of flooding.
Applications
The KBFU series is designed to drain water from construction sites, mines, and quarries—wherever the pumped medium contains sand, sludge, or fine aggregate that damages standard centrifugal pumps. The durable cast-iron construction of the hydraulic unit and impeller coated with a wear-resistant chromium-alloy layer withstand difficult operating conditions, significantly reducing the risk of unplanned downtime and service costs. The vertical outlet direction facilitates installation in narrow collection wells and confined excavations where operating space is limited.
A key design element is the cooling jacket surrounding the motor. Thanks to it, the pump does not need to be completely submerged in the pumped medium to maintain a safe operating temperature—the motor is cooled through the jacket wall even when the water level in the excavation is very low. This is a significant advantage during the final stage of dewatering, when little water remains and a standard pump would have to be switched off. Thermal protection built directly into the motor winding provides an additional layer of protection against overheating during long-term continuous operation.
The KBFU 50-1.5 model operates on a single-phase 230 V power supply, making it particularly practical for emergency sites where power generators are used. A capacity of 420 l/min and a head of up to 18.5 allow it to handle deeper excavations without the need for intermediate pumps.

Frequently asked questions (FAQ) – KBFU 50-1.5 slurry pump
Why choose the KBFU 50-1.5 instead of a three-phase model?
The 50-1.5 model operates on a standard 230 V power supply, eliminating the need for a three-phase switchboard at the failure site. With a power rating of 1.5 kW and a capacity of 420 l/min, it is one of the more powerful single-phase slurry pumps in the KBFU series.
What solid particles can the KBFU 50-1.5 handle?
The pump is designed to convey liquids containing particles up to 5 m in diameter—sand, construction sludge, and fine aggregate. The gray cast-iron impeller coated with a wear-resistant chromium-alloy layer provides resistance to intense abrasion.
Does the KBFU 50-1.5 require full immersion in water?
No. The cooling jacket maintains a safe motor temperature even when the water level in the excavation is very low—the pump does not need to be completely submerged to operate safely.
Where can I buy the IBO KBFU 50-1.5 pump?
The KBFU series is available through the Dambat distribution network—from authorized commercial partners, installation wholesalers, and specialist technical stores throughout Poland.
How long is the warranty for the KBFU 50-1.5?
IBO – 24-month (2-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat, Adamów 50, Grodzisk Mazowiecki.
