This line is built around the KB submersible ranges: drainage pumps for clean and dirty water, intelligent versions with built-in control, a high-head range for deep drainage, and the ZGWQ cutting range that shreds fibrous solids before they can block the impeller. All models are three-phase 380–400 V, 50/60 Hz, IP68, with pressure-resistant mechanical seals and 8 m cables as standard.

Questions buyers ask

Which voltages are available?

The KB ranges are three-phase 400 V ±10% at 50 Hz and 380 V ±10% at 60 Hz. Other voltages are available on request — tell us your local supply when you inquire.

How deep can these pumps work?

KBZ, KBZE, KBD and KBDE models are rated to 25 m water depth; the high-head SH range works to 30 m. The pressure-resistant mechanical seal design is what makes this possible.

Can the cable be longer than 8 m?

Yes — cable length is optional on all KB ranges. The SH high-head range ships with a 20 m cable as standard.
