The low-power Koller 146-400-WE circulation pump provides optimal performance with very quiet running. Thanks to SUPA STEALTH (SST) technology it adapts perfectly to the hydraulic design of the hot tub and increases energy efficiency. The pump has an integrated C-profile, is compatible with the Quick Fix Vario system and resists chemicals and UV radiation, which guarantees a long service life even with intensive operation. It is intended for systems with automatic self-drain.
The compact dimensions and a weight of 4.3 kg make handling and installation easier even in limited spaces. The two-way union allows connection without gluing and the pump can be used in a wide range of filtration applications.
