4.1 Flushing out the heating system (with pump removed)
In order to avoid undesirable interruptions in operation
and non-starting of the pump after long periods of standstill,
it is recommended for a newly-installed or converted heating
system that the system be drained, flushed through well
and then refilled again after heating up for the first time.
The system must comply with the latest state of technology.
(Positioning of expansion vessel or initial safety feed.)
3. Intended application
Circulation pumps of the series
LXE/HXE (single pumps)
LXED/HXED (twin pumps)
are used to circulate liquids in
– hot-water heating systems
They are glandless and not suitable for secondary
hot water services.
Heating water in accordance with VDI 2035, water/glycol mixture
with up to 50% glycol ratio. The pumps must not be used
in the food sector nor for drinking water.
Pumps with bronze housings should be used in industrial water
installations if the water hardness is below 20° tH (=14 °dH).
A dry running meter should be used in the case of greater water
hardness.
3.1 Operating temperature/Operating pressure
Permissible water temperature: +15 °C to +95 °C
Permissible operating pressure: max. 6 bar
Special versions (PN 16):
max. 16 bar
Check the unit’s permissible operating pressure
Ambient temperature:
max. 40 °C
Noise level: < 70 dB (A)
4. Assembly
4.2 Antifreezers (as far as necessary)
Important: Flush the piping network through particularly well
before the antifreeze mixture is filled.
Follow the antifreeze supplier’s instructions with respect to mixing
and filling, as well as the choice of material in the piping and
apparatus network (pay particular attention to protection against
corrosion!). Water/glycol mixture up to 50% glycol ratio permissible.
Over 10% glycol ratio, correct the pumping data of the pumps
accordingly.
