5.6 Drive
The power consumption of the pump at the operating design point is specified in the data sheet and
works certificate. If the operating design point was not known when the pump was dispatched, the power
consumption can be read off the appropriate performance curves. The max. density, the max. viscosity
and a safety margin are to be allowed for.
Care must be taken when selecting the motor size to ensure that the excess power is not too great. Dur-
ing start-up the magnetic drive could otherwise stop.
The magnetic drive rating at the nominal speed of 2900 rpm is given in the pump data sheet.
If the motor power exceeds this rating, it is necessary to check the stoppage of the magnetic drive.
The same also applies if the required drive rating exceeds 80 % of the magnetic drive rating.
Consult ITT Goulds if necessary.
Different operating data can be achieved without changing the pump through the use of different speeds,
e.g. by means of a frequency converter.
The pump with base plate and motor is illustrated in the installation drawing.
The operating manual of the motor manufacturer must be observed.
A motor with a valid ATEX certificate is to be used if employed in zone 1 and 2.
5.7 Coupling
If one coupling half engages with the other, the claw section is normally to be mounted on the pump shaft
and the coupling half with the smooth end face on the motor shaft.
Observe the operating manual of the coupling manufacturer.
NOTICE:
A coupling with a valid Atex certificate is to be used if deployed in zone 1 and 2.
Regulations exist, e.g. for the following details:
• Arrangement of the coupling halves
• Max. bore diameter
• Max. transmitted power
• Spacing of the coupling halves
• Maximum values for offset and angular misalignment
Should the pump housing and motor remain on the base plate for repair work, a spacer type coupling is
required.
