Noise Level
The noise generated by a pump depends on different factors. Most important are: power,
speed and brand name of the motor, whether there is cavitation or not, operating point of
the pump, and handling of small quantities of air. A guide value for the sound pressure level
measured in dB (A) at a distance of 3 feet from the pump with a 2 pole motor operating
at 60 Hz in ideal circumstances with cold water is 78 dB(A) for pumps up to 5 hp, 83 to
85 dB(A) for pumps with motors ranging from 7.5 to 50 hp. For pumps with 4 or 6 pole
motors, the value can be decreased with +/- 8 dB(A).
Name Plate
Model #
The various versions of the SMVT are identified by a product code number on the pump
label. This number is also the catalog number for the pump. The meaning of each digit in
the product code number is shown in the Appendix. Not all combinations are possible;
consult your Goulds Water Technology distributor for specific requirements.
Performance
Performance curves for your Goulds Water Technology Model SMVT may be found in the
selection program available on www.xyleminc.com/brands/gouldswatertechnology. The
correct performance curve can be determined from the name plate model number as defined
above. You will need to know the pump model number.
