SERIE VERTINOX

3.3Working conditions

-Liquid temperature: Low temperature : -20 ~+70
Normal temperature : +15 ~+70
Hot water : +70 ~+104
-Flow range: 0.4~120m3/h
-Maximum pressure: 30bar
-pH value range: PH3~9
-Maximum ambient temperature: +50
-Maximum elevation: 1000m

3.4 Pumped liquids

Thin, non-fl ammable, non- explosive liquids , not containing solid particles or fi bres.The liquid
must not attack the pump material chemically. When pumping liquids with a density and/or visc
sity higher than that of water, oversized motors must be used, if required.
-VERTINOX For liquid transfer, circulation and pressure boosting of cold or hot clean liquids.
4. DATOS TÉCNICOS

4.1 ambient temperature

Maximum +40 . If the ambient temperature exceeds +40 or if the motor is located 1000 metres
above sea level, the motor output(P2) must be reduced due to the low density and consequently
low cooling effect of the air(Figure 1). In such cases, it may be necessary to use a motor with a
higher output.
Fig.1 Relationship between motor output (P2) and ambient temperature
Example:
Figure 1 shows that P2 must be reduced to 88% when the pump is installed 3500 metres above
sea level. At and ambient temperature of 70oC,P2 must be reduced to 78% of the output.
