IBO KBFU 80-3.7 400 V submersible sludge pump
The KBFU 80-3.7 is a three-phase sludge pump with a power rating of 3.7 kW, powered by 400 V, with a DN 3" connection and a head of up to 29 m. The model features a SiC-SiC / SiC-SiC mechanical seal - full ceramic on both sides of the seal provides greater resistance to abrasive particles than the carbon seal solutions used in smaller models in the series.
Who it's for
-
Open-pit mines and mining facilities - the SiC-SiC / SiC-SiC seal is a significant advantage when pumping media with a high content of quartz sand and other abrasive particles.
-
Construction companies carrying out deep excavations - a head of 29 m allows water to be pumped from deeper foundations without staging the installation.
-
Hydraulic engineering contractors - the combination of a capacity of 920 l/min and a head of 29 m meets most requirements for draining linear and point facilities.
-
Industrial plants with permanent installations - the 3.7 kW motor is suitable for continuous operation in permanent drainage systems in production halls and industrial facilities.
-
Drainage system installers and designers - well-documented specifications and a proven design make it easier to select the pump for construction and industrial projects.
Applications
The KBFU series is designed to drain water from construction sites, mines and quarries - wherever the pumped medium contains sand, sludge or abrasive particles that damage standard centrifugal pumps. The durable cast-iron hydraulic unit and impeller coated with a highly wear-resistant layer withstand harsh operating conditions, reducing the risk of unplanned downtime and service costs. The vertical DN 3" outlet makes it easy to install and connect discharge hoses directly above the pump.
A key element of the design is the cooling jacket surrounding the motor. Thanks to it, 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 water level in the excavation is already very low. Thermal protection built into the motor winding provides an additional layer of protection against overheating during prolonged continuous operation.

Frequently asked questions (FAQ) – KBFU 80-3.7 slurry pump
How does the SiC-SiC / SiC-SiC mechanical seal differ from the SiC-SiC / Carbon-SiC seal used in smaller models?
W the SiC-SiC / SiC-SiC mechanical seal, both sealing faces are made of silicon carbide, a material with very high hardness and abrasion resistance. W a seal with a carbon component (Carbon-SiC), one side is less hard, which can shorten its service life when exposed to abrasive particles. The 80-3.7 model with a full ceramic mechanical seal is the right choice wherever the medium contains more hard aggregate.
How do I connect a discharge hose to the KBFU 80-3.7 pump?
The 3" discharge outlet is threaded – connect the discharge hose using a clamp or a 3" quick coupling. Using smaller-diameter hoses with a reducer is possible, but it limits system performance.
What is the difference between the KBFU 80-3.7 and the KBFU 80-2.2 T?
The 80-3.7 model has higher power (3.7 vs. 2.2 kW), greater head (29 vs. 19 m), and a SiC-SiC / SiC-SiC mechanical seal instead of SiC-SiC / Carbon-SiC. Its flow rate is slightly lower – 920 vs. 1,000 l/min. It is the right choice for deeper excavations and more abrasive media.
Where can I buy the IBO KBFU 80-3.7 pump?
The pump is available from Dambat dealers, plumbing wholesalers, and specialist technical stores throughout Poland. Dambat does not sell directly.
What is the warranty period for the KBFU 80-3.7?
IBO – 24-month (2-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat, Adamów 50, Grodzisk Mazowiecki.
