The U3 K(S) special is a variant of the U3 K(S) designed to pump aggressive media such as brine from water softeners, brackish water, condensate from gas condensing boilers, silage liquid, whey or liquid fertilizer.
Residential grey water from dish washers or washing machines (even boil wash program) or outdoor applications like drainage or rainwater can easily be handled by this pump.
Depending on the application it can be used either in a fix installation or as a mobile pump. For fix installations the pump can be combined with existing sumps but also with a variety of our chemically resistant tanks.
Aggressive media are not precicely specified and occur in countless different compositions. In order to provide reliability and warranty, please contact our technical support for consultance.
The U3 K(S) spezial provides the same technical features like the standard model U3 K(S). Guide rail systems offer the advantages of quick and easy maintenance. The Easyfix installation sets are particularly convenient. They are pre-assembled ready to plug in and can be installed as single or duplex systems.
Despite its high range of possible applications, the U3 K(S) spezial must not be used to pump effluent containing faeces or wastewater from urinal systems.
If submersible pumps are being used outdoors, the mandatory minimum length of the power cord is 10m. This is a directive from the VDE regulation 0100.
