Reliable dirty and wastewater pump for building and groundwater drainage.
The Wilo-Rexa MINI3 is a standard submersible sewage pump with ideal features for the basic drainage of houses and plots. The 40 mm free ball passage is perfect for the transport of dirty water and sewage-free sewage. The pump can be flexibly used for stationary or portable wet well installation. If the pump is installed in a DrainLift WS 50 pump chamber, the pumping of sewage containing sewage is also possible, as the system is approved in accordance with EN 12050-1. The optimised hydraulics ensure high reliability for universal use with different fluids. The compact design allows installation even in narrow drainage pits. The oil-filled sealing chamber and double sealing ensure longer maintenance intervals. Maintenance can be carried out conveniently thanks to direct access to the most important components.
Features/Product benefits
- Best efficiency and high operating safety thanks to improved hydraulics
- Easy installation even in narrow drain pits thanks to the integrated condenser, light weight and compact design with threaded flange
- Reliable use during drainage in different applications thanks to the corrosion-free impeller and cast cable.
- Longer maintenance intervals thanks to the high-volume sealing chamber and double seal
- Fast maintenance thanks to direct access to the sealing chamber and pump housing
Construction
Submersible pump for stationary and portable wet well installation in intermittent operation.
Liquids
