Motor selection
Motors shall have nameplate power ratings, excluding the service factor ( if any), at least equal to the percentages of power at pump rated conditions given in below table. However, the power at rated conditions shall not exceed the motor nameplate rating.

Motor nameplate rating		Percentages of rated pump power (%)
(KW)	(HP)
< 22	< 30	125
≥22 ~ 55	≥30 ~ 75	115
≥ 55	≥ 75	110

For higher coolant temperatures and / or site altitudes higher than 1000 m above seal level, the specified motor output must be reduced.
Revise as shown in the picture below:
Vibration
In the operating range of 0.6 to 1.2 x Q_Opt: Veff ≤ 4.5 mm/s

Noise
According to ISO 3746
Attention must be given to the exposure of personnel to the noise, and local legislation will define when guidance to personnel on noise limitation in required, and when noise exposure reduction is mandatory. This is typically 80 to 85 dBA.

The usual approach is to control the exposure time to the noise or to enclose the machine to reduce emitted sound.

You may have already specified a limiting noise level when the equipment was ordered, however if no noise requirement were defined, then attention is drawn to the following table to given an indication of equipment noise level so that you can take the appropriate action in your plant.

Pump noise level is dependent on a number of operational factors, flow rate, pipework design and acoustic characteristics of the building, and so the values given are subject to a 3 dBA tolerance and cannot be guaranteed.
