Pump curves:-
The XB530 pump curve is not included below because it is not relevant to the
installation of the product. The XB530 (25/6) and XB531 (15/6) pump curves are
identical and are shown below. Both XB530 and XB531 are supplied set at constant
speed Ι Ι Ι.
Differential Pressure Variable Δp-v (Ι, Ι Ι, Ι Ι Ι)
Recommended for two-pipe heating systems
with radiators to reduce the flow noises at
thermostatic valves.
Constant differential pressure Δp-c (Ι, Ι Ι, Ι Ι Ι)
Recommended for underfloor heating or
for large-sized pipes, applications without
a variable pipe network curve (e.g. storage
charge pumps) or single pipe heating systems
with radiators.
Constant speed (Ι, Ι Ι, Ι Ι Ι)
Recommended for systems with fixed system
resistance requiring a constant volume flow and
for replacement of AC pumps.
