5.2.3 DIRECTION OF ROTATIO N
Serious damage can result if the pump is started or run in
the wrong direction of rotation.
Ensure that the direction of rotation is correct before first start-up
or if maintenance work has been carried out on the electric power
supply.
Direction of rotation must correspond to the arrow
attached or engraved in the pump.
Check direction of rotation when motor is apart (coupling spacer
dismantled or motor not coupled to pump). If not feasible due to
pump design (pump fitted with rigid coupling) it is necessary to
check that pump shaft turns freely after the test and before final
pump start.
To check direction of rotation start motor briefly and check
direction of rotation just before rotation stops. If direction of
rotation must be modified then reverse two phases in motor
junction box.
It is possible to change two phases in the control cabinet on
motor starter connections. If this solution is preferred then
it will be necessary to modify the identification of the cables in
the electrical drawings too.
5.2.4 NOISE LEVEL
Noise level of a complete pump set depends on motor type and
speed, on quality and wear of flexible coupling (if concerned), on
fluid velocity, piping design, … Values given hereafter are only
indicative and based on fan cooled electric motors average noise
levels.
The test must be perfomed on the supplied pump if the
noise level must be certified.
If noise level is higher than 85dBA, personel working in
pump area should wear hearing protections.


Suction flange axis is horizontal and the face is vertical.

Discharge flange axis is vertical and the face is horizontal.
5.2.6 PERMISSIBLE FORCES A ND MOMENTS
No other stress than the one due to tightening of
pipe and pump flanges together should apply. No
stress must be applied to pump casing by the pipe work. A
pre-stress may exceptionally be applied to flanges to
compensate a pipe expansion. But in any case the resulting
forces should not exceed values given hereafter.
The values are determined on the basis of ISO
5199/ISO 13709(API610).
