Flexible drainage for private homes and properties.

The compact Wilo-Padus MINI3 submersible pump is the ideal choice for wet-well installation in single- and two-family homes and on private properties. It reliably pumps wastewater and sewage (free of fecal matter, in accordance with DIN EN 12050-2) and is suitable for both stationary installation in a pump chamber and portable use. Optimized hydraulics made of composite material allow for use with a wide range of fluids. Two hydraulic options are available: a high-efficiency multi-channel version and a vortex version with a large solids passage.

Its compact design makes installation easy, even in narrow drainage pits. The design enables longer maintenance intervals, while direct access to key components ensures convenient maintenance.

Features/Product Advantages

Optimized hydraulics with enhanced performance
Stainless steel motor housing and composite hydraulics ensure excellent corrosion resistance—even when the motor is not fully submerged—resulting in high operational reliability and a long service life
Easy installation—even in narrow sumps—thanks to a compact design, integrated capacitor, low weight, and threaded connection with a non-return valve
Extended maintenance intervals due to a large-volume sealing chamber and double seal system
Easy maintenance with direct access to the sealing chamber and pump housing
