Typical Applications

Larger residential and commercial hydronic heating circuits with high pipe-friction losses.
Boiler, buffer-tank and calorifier primary circuits requiring flow up to 11.5 m3/h.
Air-conditioning and chilled-water secondary circulation.
Multi-zone and long-run systems with variable demand.
Replacement of large fixed-speed circulators where energy saving is required.

Operating Conditions

Suitablefluids: heatingwater (to VDI 2035), clean water, water/glycol mixtures to a maximum mixing ratio of 1:1.
Not forsolids-bearing, aggressive or explosive liquids.
Liquid temperature range -10 C to +110 C; maximum ambient temperature +40 C.
Maximum system working pressure 10 bar.
Power supply 1~ 220-240 V, 50 Hz; enclosure class IP44, insulation class F.
Integrated frequency inverter with automatic (proportional-pressure) mode, constant-pressure and constant-speed modes selected on the control panel; LED display of actual input power.
Wet-rotor, glandless canned-motor design: the pumped liquid lubricates the ceramic bearings and cools the motor. Never run dry.
Install with the pump shaft horizontal and the terminal box / control panel not facing downwards; maintain a minimum inlet pressure to prevent cavitation noise at high liquid temperatures.
