Noise Characteristics
WARNING
The addition of coarse solids, froth or cavitating conditions can significantly increase the noise levels in both the
pump and piping. If accurate noise levels are required for these conditions, field-testing will be required.
If running within the normal limits of operation and with clear water, the noise level for the pump alone (with gear box and motor
noises shielded) does not exceed 85 dB(A) at one meter.
Noise levels from motor and gear reducer must be added to the above in accordance with standard acoustic formulas, taking
into account the distance between units. For belt driven units, add an additional 2 dB.
4.5
Accessories
Couplings, pulleys, belts, motor mounts and/or base plates may be provided. Refer to the bill-of-materials, data sheets and/or
drawings for further information.
4.6
Dimensions and Weights
Dimensions and weights are listed on the pump installation plan.
4.7
Forces and Moments at Nozzles
Suction piping is normally not used in vertical pump applications. However, if a suction extension is used, the inlet end must be
located a minimum of 1.5 pipe diameters above the bottom of the sump and no closer than 300mm (12").
Discharge flange loads are limited to the weight of the discharge pipe section supplied with the pump by GIW. Any additional
pipe loads or moments must be compensated for by the system pipe supports.
For additional information please contact your GIW / KSB representative.
