Reliable sewage and wastewater pumps for domestic and site drainage systems.
The Wilo-Rexa MINI3 is an ideal standard submersible sewage pump for domestic and site drainage applications. With a 40 mm solids passage, it is perfectly suited for transporting sewage and greywater (wastewater without fecal matter). The pump offers flexible installation options, suitable for both stationary and portable wet-well setups. When installed in the DrainLift WS 50 collection tank, it can handle sewage containing fecal matter, as the system is certified according to EN 12050-1. Optimized hydraulics ensure high reliability for this versatile pump, capable of handling a wide range of fluids. Its compact design allows for easy installation even in narrow drainage sumps. An oil-filled seal chamber and a double seal system ensure extended maintenance intervals. Direct access to key components significantly simplifies maintenance tasks.
