How to read the curve charts
Curve conditions
The guidelines below apply to the curves shown on the
following pages:
1. Tolerances to ISO 9906, Annex A.
2. The curves apply to the performance of
sin-
gle-phase pumps
. For other versions, please see
the exact curves in WinCAPS or WebCAPS.
3. Measurements have been made with airless water
at a temperature of +68 °F (20 °C).
4. The curves apply to a kinematic viscosity of
1 St (1 mm
2
/s).
5. Due to the risk of pump overheating, the pumps
should not be used below the minimum flow rate
indicated by the
bold
-faced curves.
Note:
We do not recommend constant operation at
a flow rate below 10 %.
6. If the pumped liquid density and/or viscosity is
higher than that of water, it may be necessary to use
a motor with a higher performance.
7. Motor speed:
2-pole = 3400 RPM
4-pole = 1690 RPM
