6.2 Maximum differential and discharge pressures
The maximum differential pressures and discharge pressure specified
below must not be exceeded.
6.3 Maximum permissable moment
For motors of 45kW capacity onward it is recommended, due to the
inertia of the motor, to equip the coupling between the pump and
gearmotor with a safety device ensuring that the maximum
transferred moment does not exceed the pump's maximum allowable
moment given in the table below.
The coupling supplier’s demands for lining up must be kept.
6.4 Maximum permissable temperature
Check the nameplate of the pump to see the maximum permissable
temperature limit for the pump. This temperature must not be
exceeded.
Furthermore, the maximum rotor temperature should be checked.
Rotors with maximum temperature of 110°C are marked with . or ...
or .... on the spline.
Rotors with maximum temperature of 180°C are marked with .. on the
spline. See fig. 17 for DW1-5 and fig. 18 for DW6&7 and the
description under the illustrations on the left.
6.5 Sound Pressure and Sound Power Level
Measurements have been carried out in accordance with:
DS/ISO 3744 grade 2, class 2 for DW1
DS/ISO 9614-2 for DW2-7
Tolerance ±3dB.
