Wilo-DrainLift SANI-XL


Large wastewater lifting unit with twin pump for apartment buildings and industrial facilities.

The large Wilo-DrainLift SANI-XL sewage lifting unit is ideal for use in large apartment blocks and industrial facilities with uncontrolled wastewater intake due to its large twin pump volume and electric motor with selectable "continuous operation" and "intermittent operation" modes. The easy-to-install unit is virtually universal thanks to its 44 mm to 65 mm free passage, selectable air inlets and an optional version for particularly aggressive pumped liquids.

The user-friendly design maximizes ease of maintenance for the user.
