High flow and high head secondary hot water loops in commercial or larger residential systems, along with solar heating and geothermal applications, are effectively served by the Lowara TLCHN 25-8L. This wet rotor circulator pump delivers robust performance for high capacity commercial potable hot water systems.
Three speed manual selection enables optimisation across varying system demands. Speed 1 at 260 W draws 1.23 A, Speed 2 at 270 W draws 1.24 A, and Speed 3 at 286 W draws 1.25 A on 240 V single-phase supply. Maximum head is approximately 8 m with flow reaching 160 L/Min.
The pump body is constructed from stainless steel with ceramic components throughout. The axial and radial bearings are ceramic for extended service life, while the composite impeller provides efficient hydraulic performance. The integrated terminal box is axially positioned in the motor for simplified electrical connection.
Installation is suitable for horizontal or vertical piping with motor axis horizontal. Threaded connections include 1"1/4 and 1"1/2 sizes. Liquid temperature capability ranges from +2°C to +110°C with recommended maximum of 65°C. Maximum operating pressure is 10 bar PN10 with insulation class 180 (H).
