IBO KBFU INOX 50-0.75 M submersible sludge pump, 230 V
The KBFU INOX 50-0.75 M is a single-phase 0.75 kW sludge pump powered by 230 V, equipped with a vertical float switch and an AISI 316 stainless steel motor housing. The KBFU INOX series is designed for operation in environments requiring increased corrosion resistance, while remaining fully suitable for pumping water containing sand, sludge, and abrasive particles up to 7 mm.
Who is it for
-
Earthworks and construction contractors – the built-in float automatically stops the pump when the water level is low, protecting the motor from dry running without the need for supervision.
-
Mining and stone-processing companies – AISI 316 stainless steel and support for particles up to 7 mm enable operation in environments with more acidic media and mineral contaminants.
-
Maintenance departments and technical service providers – continuous operation, IP68 protection, and an automatic float are suitable for installations requiring prolonged unattended operation.
-
Property managers and commercial facilities – the compact 15.2 kg weight and 230 V power supply make it easy to start the pump quickly when a garage or basement is flooded.
-
Equipment rental companies and distributors – the model with an automatic float and corrosion resistance expands the product range with an INOX version ready for field use.
Applications
The KBFU INOX series is designed to drain water from construction sites, mines, and quarries—anywhere the pumped medium contains sand, sludge, or other mechanical impurities. The AISI 316 stainless steel motor housing and shaft provide corrosion resistance in conditions unsuitable for standard gray cast iron models. The KBFU INOX 50-0.75 M model pumps water down to a level of 90 mm, while the vertical float switch automatically stops the pump before the liquid reaches a critical level.
The power cable is fitted with a plug, and the threaded DN 2" connection allows the pump to be started quickly without specialist tools. Thermal protection built into the motor winding provides additional protection during prolonged continuous operation.

Frequently asked questions (FAQ) – KBFU INOX 50-0.75 M slurry pump
What is a vertical float switch, and how does it differ from a standard float?
A vertical float switch is integrated into the pump body and operates vertically along its axis, unlike a conventional cable float that moves freely from side to side. The vertical design is more compact and works better in confined sumps where there is not enough space for a traditional float to move freely. It also provides dry-run protection by automatically switching off the pump when the water level is too low.
How does the KBFU INOX differ from the standard KBFU series?
The key difference is the material of the motor housing and shaft—in the INOX series, AISI 316 stainless steel is used instead of gray cast iron. AISI 316 is more corrosion-resistant than the more common AISI 304, especially in media with increased acidity. It is the right choice for conditions where the standard cast-iron model would corrode too quickly.
What particles can the KBFU INOX 50-0.75 M handle?
The model allows solid particles up to 7 mm in diameter—more than the standard 5 mm in most KBFU series models. The steel and glass-fiber-reinforced polyamide impeller, along with the ceramic/carbon/NBR double mechanical seal, provides resistance to abrasion when pumping mineral suspensions.
Where can I buy the IBO KBFU INOX 50-0.75 M pump?
The pump is available from Dambat’s commercial partners, specialist installation wholesalers, and technical stores. Dambat does not sell directly.
