2.3.3 Correction factor - Temperature
When the temperature of the water exceeds 15°C,
the pump’s capacity will be affected with respect
to the specified values.
To determine the output at a higher temperature,
the correction factor can be used.
Capacity at water temperature higher than 15°C :

Normal atmospheric air contains water vapor. In this case water will condense inside the pump and will
create a higher flow.
Below you can find a correction factor table for the performance based on condensing gas with an inlet
temperature of 50°C 100% saturated and water temperature of 15°C.
