Wilo Rexa MINI3 Wastewater Pump – Reliable Drainage

The Wilo Rexa MINI3-V04.11/T06-540/O-10M submersible pump is a robust solution for removing wastewater without fecal matter and contaminated water, both in domestic and industrial installations. The pump design allows for intermittent operation, as well as stationary or portable installation. This is a versatile device that will perform well in many applications where effective and reliable water drainage is required.

Construction and application

The pump is designed for pumping wastewater without fecal content and contaminated water with a small amount of sand and gravel. Made of high-quality materials, such as cast iron (housing) and stainless steel (motor housing), it ensures long-lasting and trouble-free operation. The impeller made of polypropylene (PP) is resistant to corrosion and mechanical damage. A vertical discharge port with a thread facilitates connection to the installation. A surface-cooled motor with automatic thermal control guarantees safe operation even under heavy load. The length of the power cable is 10 meters, which provides convenience during installation and use.

Key features and benefits

• Versatility: Can be used in stationary and portable installations and in intermittent mode.
• Efficiency: Maximum lift height is 10.97 m, and maximum flow rate is 20.88 m³/h, ensuring effective water drainage.
• Durability: The cast iron housing and stainless steel motor housing guarantee corrosion resistance and long life.
• Safety: Surface-cooled motor with automatic thermal control protects against overheating.
• Easy installation: Compact design makes it easy to install even in tight spaces.
• Contamination resistance: The free-flow impeller allows pumping water with solid particles up to 40 mm in diameter.
• Long cable: 10-meter cable provides flexibility during installation.
• Motor protection: Bimetallic protection protects the motor from overload.

Technical parameters in practice

The Wilo Rexa MINI3 pump operates at a voltage of 400 V and a frequency of 50 Hz, drawing a current of 1.6 A with a power of 0.83 kW (P1) and delivering a power of 0.6 kW (P2). It can be submerged to a depth of 7 meters, and its IP68 protection class guarantees tightness against water and dust. Insulation class F provides high thermal resistance of the motor. Thanks to the nominal S3 15% operating mode, the pump is adapted for intermittent operation, which extends its service life. A G 1½ inch discharge connection allows easy connection to an existing hydraulic installation.

Applications

The Wilo Rexa MINI3 pump is ideal for:

• Draining wastewater without fecal matter from homes and public buildings
• Draining flooded basements and utility rooms
• Pumping contaminated water from excavations and foundations
• Draining rainwater
• Working in DrainLift WS 50 systems (with the possibility of pumping wastewater containing fecal matter).

Please remember that the pump does not have a float switch or a plug – it requires a permanent connection to a controller and appropriate electrical circuit protection!
