A convenient lifting system with alarm contacts for single-room wastewater disposal; capable of handling wastewater from toilets, showers, dishwashers, and washing machines, as well as condensate from condensing boilers located below the backflow level.

The Wilo-DrainLift MINI5 is a convenient lifting system designed for the safe handling of domestic wastewater. Featuring a modern, aesthetic design and compact dimensions, this series is the ideal choice for situations where gravity drainage is not possible. The system offers customizable configuration options, including a choice of pressure connections (horizontal or vertical DN 32/40), multiple DN 40/50 inlets, and either side or central toilet connections. The pressure outlet eliminates the need for complex additional piping, making installation straightforward—particularly during modernization and renovation projects. To minimize the risk of clogging and ensure high operational reliability, the system is equipped with a sewage pump featuring a rotating cutter.

Type

Wilo-DrainLift MINI5-XS/C

Compact, ready-to-connect lifting system equipped with a submersible pump. Level detection via level sensor. Ventilation unit integrated into the inner cover, equipped with an activated carbon filter. In addition, the lifting system is equipped with a buzzer and a potential-free alarm contact (max. switching capacity: 42 V DC, 500 mA; contact type: NC/normally closed). If a high water level occurs in the collection tank, the buzzer emits an audible alarm. An external alarm device can also be connected via the potential-free contact. The collection tank cover completely seals the system.

Up to four connections are available:

1× 40 mm (DN 40) inlet, without non-return valve, facing upwards, sealed at the factory.
2× 40/50 mm (DN 40/50) inlets, with non-return valves, horizontal (left and right), open at the factory.
1× 32/40 mm (DN 32/40) discharge connection, with non-return valve, facing upwards, open at the factory. If required, the discharge connection can be positioned horizontally to the right; the corresponding opening is sealed at the factory.

Wilo-DrainLift MINI5-XS/WC

Compact, ready-to-connect submersible lifting system featuring a submersible pump. The submersible pump is equipped with a rotating cutter. The cutter reliably shreds faecal matter in the sewage. Level detection is achieved via a level sensor. The venting unit is integrated into the cover and includes an activated carbon filter. In addition, the lifting system is equipped with a buzzer and a potential-free alarm contact (max. switching capacity: 42 V DC, 500 mA; contact type: NC/normally closed). If a high water level occurs in the collection tank, the buzzer emits an audible alarm. An external alarm device can also be connected via the potential-free contact. The collection tank cover completely seals the system.

Up to five connections are available:

1× 40 mm (DN 40) inlet, without non-return valve, facing upwards, sealed at the factory.
2× 40/50 mm (DN 40/50) inlets with non-return valves; horizontal (left and right) orientation; open at delivery.
1× 110 mm (DN 110) WC connection; forward orientation; open at delivery. Can be configured for horizontal left orientation if required (corresponding opening is closed at delivery).
1× 32/40 mm (DN 32/40) discharge connection with non-return valve; upward orientation; open at delivery. Can be configured for horizontal right orientation if required (corresponding opening is closed at delivery).
