Typical Applications
- Domestic andlight-commercial hydronic heating: radiator, underfloor and fan-coil circuits.
- Boiler,calorifier and solar thermal primary circuits.
- Hot-water recirculation to keep draw-off points primed.
- Air-conditioning and chilled-water secondary circulation.
- Water/glycolmixtures up to1:1 for frost-protected systems.
Operating Conditions
- Suitablefluids: heatingwater (to VDI 2035), clean water, water/glycol mixtures to a maximum mixing ratio of 1:1.
- Not for solids-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 classF.
- Three manually selectable speeds (I / II / III) via the terminal-box switch; the motor is non-overloading at every speed.
- 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.
Materials of Construction
- Pump body: Castiron
- Impeller: PP
- (polypropylene) Shaft: Ceramic
- Bearings: Ceramic
- Rotor can / motor: Stainless steel can, wet-rotor canned motor
- Connection: Threaded union (BSP)
