Xylem Lowara DOC 3 and 7 drainage submersible pumps. The Doc range of pumps are suitable for applications including the emptying of residential sump pits, rain water tanks, garden and lawn irrigation and the emergency draining of flooded areas or rooms.
The Doc7 has a max head of 11m, nearly twice the power of the Doc3 with a much improved flow rate. Both pumps in standard format can handle solids to a maximum of 10mm but the Doc7 has a vortex "VX" propeller option. This vortex impeller is less efficient (drops the Doc7 max head to 7m) but it can then handle solids of up to 20mm.
Variants of this range come with or without a float switch, please check which you need before you order.
