概要
Efficient submersible sewage pump in non-clog design with macerator for house and site drainage for detached and semi-detached houses.

主な特長

• Macerator with double shear effect ensures excellent clogging resistance
• Optimised hydraulics/macerator combination for a broad cover of the delivery head with the lowest power requirement for domestic power connections
• Use of the smallest possible pipework guarantee low overall installation costs
• Low weight ensures easy application in the domestic area
• High-quality motor with double sealing ensure long service life
• Stainless-steel motor housing provides high resistance to corrosion, even when the motor is non-immersed

Advantages / 製品説明
The Wilo-Rexa MINI3-S grinder pump ensures safe house and site drainage. The compact design and the radial macerator with double shear effect allow you to safely drain small pump sumps, such as soakaways or catchment shafts. In addition, using the smallest-possible pipework reduces installation costs. The high-quality motor has a double seal and is easy to maintain. The stainless steel motor housing is corrosion-resistant, even when non-immersed. The low weight and the built-in plug enables easy installation: Simply plug it into the existing socket. Pumps with an attached float switch start automatically. The pumps are switched on and off depending on the fill level.
