Wilo-Rexa MINI3-V04.11/M06-523/A-10M - Reliable Submersible Wastewater Pump

Item number: 3094012

The Wilo-Rexa MINI3 is a versatile submersible pump designed for wet, stationary and portable settings, ideal for intermittent operation. Designed for pumping fecal-free wastewater and contaminated water (with a small amount of sand and gravel), it is used in domestic applications for both building drainage and groundwater discharge. When installed in a DrainLift WS 50 sump, the system allows pumping of wastewater containing fecal matter - according to EN 12050-1 certification.

Key Benefits

• Optimized hydraulics for high efficiency and reliable operation.
• Compact, compact design for easy installation even in narrow drainage sumps.
• Long maintenance intervals thanks to capacious double-sealed seal chamber.
• Quick and easy maintenance thanks to direct access to key components such as the seal chamber and pump body.
• Environmentally friendly features - optimized hydraulic system minimizes unscheduled service visits.

Design Characteristics

The Wilo-Rexa MINI3 pump has a free-flow impeller and a vertical threaded connection. The hydraulic body is made of gray cast iron (EN-GJL-200), and the impeller is made of plastic (PK-GF30). The 1~ surface-cooled motor, with integrated operating capacitor and automatic thermal control, is made of stainless steel (1.4301). The oil-filled seal chamber, equipped with a double seal (a seal ring on the motor side and a mechanical seal on the pump side), ensures long-term operation without frequent maintenance. The pump is equipped with a 10m detachable power cable with float switch and built-in plug (CEE 7/7).

Application
