5.7 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 consump-
tion 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. During
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 ex-
ceeds 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.
5.8 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 manu-
facturer.
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 mis-
alignment.
Should the pump housing and motor remain on the
base plate for repair work, a spacer type coupling is
required.
5.9 Coupling guard
The pump may only be operated with a coupling
guard in accordance with the accident prevention
regulations.
It must be ensured that the coupling guard
used is made of spark-free material.
5.10 Final check
Check the alignment of the coupling again in accor-
dance with
Section 5.3 .
It must be possible to easily turn the unit at the cou-
pling by hand.
5.11 Electric connection
Only have the electric connection performed by a
qualified electrician. Compare the available
mains voltage with the information on the
type plate of the motor and select a suitable
circuit.
It is urgently recommended to use motor protection
facilities (motor protection switch).
In potentially explosive areas IEC 60079-14
must also be observed for the electrical instal-
lation.
It must be ensured that the pump is grounded.
This can be achieved in the simplest case by
using a toothed-lock washer or contact disc at
the housing support if the substructure itself is
grounded.
Otherwise, grounding must be ensured by other
means, e.g. cable bridges.
Units supplied by Goulds (pump and base plates) are
to be grounded using suitable devices on the base
plate.
