Large-scale twin-pump lifting system for multi-family residential and commercial buildings.

With its large tank volume and motor modes supporting both continuous and intermittent operation, the Wilo-DrainLift SANI-XL large-scale twin sewage lifting system is the ideal solution for quiet operation in large apartment complexes and commercial buildings handling uncontrolled sewage inflows. It offers flexible application and easy installation thanks to a 44 mm or 65 mm solids passage, freely selectable inlets, and optional specifications for handling particularly corrosive media. Spring-loaded non-return valves minimize noise levels at the end of each pump cycle. The user-friendly design makes maintenance particularly convenient.

Features/Product Advantages

Compact design and low weight ensure simple installation and easy transport
High operational reliability due to the twin-pump system, high switching volume, thermal motor protection, and a mains-independent alarm system

Construction

Ready-to-connect, submersible twin-pump lifting system for pumping sewage containing fecal matter.

Applications

As a lifting system, it can be installed free-standing or against a wall within a building, or installed concealed on the floor within a pump chamber:

For situations where sewage cannot be discharged directly into the sewer system via gravity flow
For drainage when the discharge point is below the backflow level, ensuring protection against backflow

Sewage containing faeces
Sewage free of faeces

The "C" version is used for pumping the following corrosive liquids:

Boiler condensate
Seawater
Maximum sodium chloride content (brine): 30 g/l, at a maximum temperature of 20°C
