Amacan S

Summary

Product identification

The KSB Amacan S is a submersible pump designed for installation in a discharge tube, operating at 50 Hz.

Designation Key Example: Amacan S 1000-655 / 25O 8 UTG2

• Amacan: Type series

Feed water

The Amacan S is suitable for handling various water types, including:

• Grey water
• River water
• Stormwater
• Activated sludge (Max. dry substance 2 %)
• Seawater
• Brackish water

Recommendations:

• Waste water (without long fibres and large solid particles) and surface water require pre-screening.
• For seawater and brackish water, Material variant G3 is recommended for temperatures up to 25 °C, requiring the use of Zn anodes (anodes to be checked every 6 to 12 months).
• Screen bar opening sizes vary by pump size; See the official PDF for exact tabulated values.

Electrical
