GXR
- For clean water containing solids up to 10, 12 mm grain size.
- For draining rooms or emptying tanks.
- Extraction of water from ponds, streams or pits and for rainwater collection.
- For irrigation purposes.
GXV
- For clean or slightly dirty water, containing solids up to 25 mm grain size.
- Particularly suitable for liquids with a high solid content.
- Extraction of water from ponds, streams or pits and for rainwater collection.
- For irrigation purposes.
For outdoor use a power supply cable of not less than 10 m should be used in accordance with: EN 60 335-2-41.
