1. Core Functions

Automatic Operation: Starts and stops automatically based on tank water level; supports two control methods—float switch or level sensor tube with control cabinet—minimizing manual intervention.
Dual-Pump Option: DUOLIFT models support dual-pump redundancy, enhancing system reliability.
High-Capacity Handling: 270L PE tank with high corrosion resistance; suitable for handling blackwater (including toilet waste) and greywater (excluding toilet waste) in residential and commercial buildings.

2. Key Design Features

Stainless Steel Construction: Pump body made of stainless steel for corrosion resistance and long service life.
High Compatibility: Complies with EN 12056-4 standards; fits DN50 discharge pipes; supports 45° elbow design to minimize sediment buildup.
Smart Control: Optional LC 220/221 control cabinet allows adjustment of parameters such as start levels and alarm levels; supports high-level alarm functionality.

3. Safety and Maintenance

Multiple Protection Measures: Equipped with isolation valves and check valves to prevent backflow; features dual monitoring via level sensor tube and alarm float switch.
Easy Maintenance: Flexible connection pipe design facilitates pump removal; recommended maintenance frequency is 1–4 times per year (depending on usage).
Optional Diaphragm Pump: Allows for manual tank emptying during maintenance or power outages.

4. Technical Parameters

Operating Conditions: Ambient temperature 0–40°C; liquid temperature ≤60°C (short-term); system pressure rating 6 bar.
Electrical Safety: Requires an external residual current device (RCD <30 mA); power outlet must have grounding protection.

5. Application Scenarios

Typical Uses: Locations lacking natural drainage gradients, such as basements and restrooms.
Prohibited Uses: Not to be used for discharging surface water accumulation (e.g., rainwater).

6. Additional Features

Multilingual Support: Installation manuals available in over 20 languages, including Chinese.
Eco-friendly Design: PE tank is recyclable and complies with environmental disposal requirements.
