Wilo-DrainLift XXL


Sewage lifting unit with 2 dry-mounted pumps


Sewage lifting unit for drainage of residential housing and commercial buildings (e.g. restaurants, department stores, etc.). Raw sewage that cannot be piped to the sewer system through the use of natural inclines and sewage from toilet systems below the backflow level are to be piped to the public sewer system by means of an automatic lifting unit in accordance with DIN EN 12056/DIN 1986‐100. Sewage containing mineral oils or explosive admixtures must be guided through oil precipitators and/or petrol precipitators; those containing fatty substances must go through grease traps and those with sand through sand catchers.

Fully submersible sewage lifting unit, ready for connection (flooding height: 2 mWS, overflow time: 7 days), with a gas- and watertight collection tank. Equipped with two sewage pumps of the Wilo-Drain TP 80 or TP 100 series (material: Inox and composite). Easy handling due to low total weight of system, e.g. double system with TP 80 pump only 160 kg (heaviest individual weight: pump 62 kg). Optimal tank drainage due to deep extraction by suction.

Important: The switchgear is not submersible and must therefore be arranged in such a way that it is safe from flooding.

Scope of delivery

  • Microprocessor-controlled switchgear with automatic duty cycling, standby and peak load operation, potential-free contacts and indicator lights for operation and malfunctions for each pump.
  • Elastic hose connection for ventilation DN 70.
  • Elastic hose connection for connecting a diaphragm hand pump. Kit for connecting the tank with a pump (including ventilation flange with hose).
