CHARACTERISTIC CURVES AND PERFORMANCE DATA 50 Hz n= 2900 1/min HS= 0 m
INSTALLATION AND USE
Suitable for use with clean water and liquids that are not chemically
aggressive towards the materials from which the pump is made.
The self-priming JSW pumps are designed to pump water even
in cases where air is present. As a result of their reliability and
the fact that they are easy to use, they are recommended for
use in domestic applications such as the distribution of water in
combination with small or medium sized pressure sets, and for the
irrigation of gardens and allotments, etc.
APPLICATION LIMITS
•• Manometric suction lift up to 9 m (HS)
•• Liquid temperature between -10 °C and +40 °C
•• Ambient temperature up to +40 °C
•• Max. working pressure 6 bar
•• Continuous service S1
