1. Explanatory Notes
The noise data below conform to DIN standard 45635 - Measurement of noise emitted by machines - Part 1 – Airborne noise emission,
Enveloping surface method, Basic method divided into 3 grades of accuracy and Part 24 – Measurement of airborne noise emitted by
machines, Enveloping surface method, Liquid pumps.
The noise data meet the requirements of accuracy grade 2.
DIN 45635 standards for measurement largely correspond to international stipulations such as EN ISO 3744-09.1994 and
ISO 11201-12.1995.
The equipment used for measurements meet the requirements placed on precision sound level meters DIN EN 60651.
It was submitted to the standardising authority for examination within the required period of 2 years.
The non-weighted and A-weighted sound pressure levels were used as acoustic measurands expressed in dB.
The frequency weighting curve A is defined in DIN EN 60651.
2. Prerequisites
The noise data refer to the pump without sound insulation.
The data apply without electric motor.
The noise particulars apply to the normal operating range of the pump, i.e. Q/Qopt = 0.8 – 1.2
No allowance is made for operation under extreme part-load, overload or cavitation conditions.
3. Definitions
LpA: The surface sound pressure level is the A-weighted sound pressure level averaged over the measurement surface S, expressed in dB.
LS: The measurement surface ratio is calculated from the measurement surface S, whose size depends on the position of the measuring
points.
The measurement distance is typically chosen to be 1 m from the machine outline. LS is expressed in dB.
LWA: The A-weighted sound power level is the rate of the total noise radiated by the machine into the ambient air, expressed in dB.
The air-borne sound octave spectrum supplements the surface sound pressure level LpA data and provides information on the noise
composition in the acoustic frequency range from 63 Hz to 8 kHz.
This frequency range is subdivided in octave bands characterised by their centre frequency.
4. Noise Characteristic Values
The following values are expected noise values and cannot be warranted. The values indicated do not include the measurement tolerance.
If the values are to be warranted, an allowance for design and measurement tolerances of +3 dB has to be made.

The minimum flow valve protects the pump against overheating during operation in the low load range. Increased
wear on the pump and the minimum flow system is not avoidable.
If the installation's mode of operation requires low load, at flow rates below 1.35 x Qmin (e.g. operation at extremely
low flow, filling of the boiler, stand-by heating and minimum flow rate, etc.), notification thereof shall be given. In this
case, a minimum flow valve with branch for manual operation must be used.
The characteristics of the boiler control valve can influence the behaviour of the minimum flow valve, and the valve
must be suitable for low flow operation.

The strainer in the inlet pipe serves as an additional pump protection and is destined to hold back welding beads,
scale and other impurities (>500µm) from the pump. It is not intended to as a filtration system, since the gaps within
the pumps are smaller than 500µm. A strainer with smaller mesh width can be quoted as an additional option. In any
case, a filtration system must be installed by customer, independent from the mesh size of the strainer.

KSB’s HG pumps are designed for compliance with the vibration velocity limits according to nach DIN ISO 10816-7, category I. These are
determined as overall root-mean-square values v eff [mm/s] in the frequency range of 10 – 1000 Hz.
The permissible root-mean-square value of the vibration velocity is determined by the type of assembly and the evaluation zone B.
The following applies to HG pumps, all values in mm/s

The measurement points are schematically represented in the figure above.
NDE: Non Drive End DE: Drive End
2. Prerequisites
The above-mentioned vibration velocity values shall apply under the following conditions:
1. Measurement of vibrations in steady-state operation at nominal speed or within the specified speed range (not under transient
operating conditions, not with changing speeds or loads).
Measurement at nominal flow rate or in the preferred operating range of between 0.7 .... 1.2 x Q opt (extreme part load or overload as
well as operation at cavitation are excluded), permitted operating range is defined as 0,5 .... 1.25 x Q opt .
2. The measurements are performed at the positions indicated using vibration velocity sensors. Only measuring instruments that were
calibrated within the framework of the applicable quality assurance system are used.
3. Measurement of vibration velocity in the installation/plant:
For operation in the installation/plant, the machine has to be installed in compliance with the instruction manual.
