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. Because of their reliability and the fact that they are easy to use, they are recommended for use in domestic, civil and industrial applications such as water distribution in combination with pressure tanks, and for the irrigation of gardens and orchards, etc.
Installation must be undertaken in well-ventilated closed areas or protected from bad weather.
