Lubricant Quality (recommendation) ISO high-quality oil VG 32 or VG 46 to DIN ISO 3448, TD 32 or TD 46 to DIN 51515, or equivalent. If a gear or geared variable speed coupling is included in the scope of supply, observe the manufacturer's instructions. Lubricant Quantities Bearing Lubrication Quantity Unit Radial bearing Oil ring 1.5 Liter Coupling Type Lubricant Quantity Unit Pump - motor ZIZS 2 Grease 0.16 dm3 Cooling water quality (recommendation) Only cleaned water not liable to precipitation of salts causing hardness may be used as coolant. The cooling water temperature at the outlet must not exceed 55 °C.

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.
