KBFU 80-4-4.0P T sludge pump with agitator, 400 V, 1450 rpm
The KBFU 80-4-4.0P T is a 4 kW three-phase sludge pump equipped with a four-pole motor operating at 1450 rpm and a chromium-alloy agitator. The slower motor, combined with the bottom agitator and the ability to pass particles up to 30 mm, makes this model suitable for more demanding applications—dense sludge, bentonite suspensions, and media that smaller KBFU series pumps cannot handle.
Who is it for
-
Mines and quarries with dense suspensions – the permitted particle size of up to 30 mm and operation in media with a density of up to 1200 kg/m³ are parameters unattainable in standard KBFU series models.
-
Drilling companies working with bentonite – the chromium-alloy agitator actively breaks up sediment at the inlet, enabling the pumping of dense drilling suspensions.
-
Geotechnical and foundation contractors – the combination of the agitator and 4-pole motor performs well when pumping drilling spoil from piles and diaphragm walls.
-
Industrial plants handling high-density media – the 4-pole motor running at 1450 rpm offers significantly longer service life than 2850 rpm equivalents during continuous operation in extremely demanding conditions.
-
Equipment selection engineers – the extended pH range of 5–9 allows use in mildly acidic and alkaline environments where standard models are not recommended.
Applications
The KBFU 80-4-4.0P T model is designed for pumping dense sludge suspensions, drilling spoil, and media containing abrasive particles up to 30 mm in diameter—a range far exceeding the capabilities of standard KBFU series models. A chromium-alloy agitator mounted beneath the pump impeller sets the sediment into a swirling motion, breaking up clumps and enabling them to be sucked in without the risk of blocking the hydraulics. The cast-iron construction of the hydraulic unit, with a wear-resistant coating on the impeller and agitator, ensures resistance to intensive abrasion even when pumping media with a density approaching 1200 kg/m³.
The four-pole motor operating at 1,450 rpm is the key design difference compared with the other models in the KBFU series. The lower rotational speed results in lower mechanical stresses in the drive system, reduced vibration, and longer bearing life—particularly important during continuous operation in demanding conditions. The cooling jacket keeps the motor at a safe temperature without the need to fully submerge the pump.

Frequently asked questions (FAQ) – KBFU 80-4-4.0P T slurry pump
What does the “4P” designation in the model name mean?
The designation “4P” indicates a four-pole motor operating at 1,450 rpm, whereas standard KBFU series models have two-pole motors (2,850 rpm). The lower rotational speed results in significantly longer motor life, reduced vibration, and better resistance to loads when pumping dense slurries.
What is the maximum particle size for the KBFU 80-4-4.0P T?
The model allows solid particles up to 30 mm in diameter—six times larger than the standard 5 mm in other KBFU models. The chromium-alloy agitator actively breaks up sediment at the inlet, enabling the pumping of even dense mineral and drilling slurries.
Can the KBFU 80-4-4.0P T be used for pumping bentonite?
Yes – the model is designed, among other things, for use with bentonite and other dense drilling slurries. The permissible medium density is up to 1,200 kg/m³.
Where can I buy the KBFU 80-4-4.0P T pump?
The pump is available from Dambat’s trade partners, installation wholesalers, and specialist technical stores. Dambat does not sell directly.
How long is the warranty for the KBFU 80-4-4.0P T?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat, Adamów 50, Grodzisk Mazowiecki.
