4. Application
This pump's basic function is to pump hot or cold
water, water with glycol or other low viscosity
fluids that contain no mineral oil, solid or abrasive
substances, or materials having long fibres. The
manufacturer's approval is required for use to
pump corrosive chemicals.
DANGER! Risk of explosion!
Do not use this pump to handle flammable or
explosive liquids.
Application areas:
• water distribution and boosting installations
• industrial circulation systems
• process fluids
• cooling water circuits
• fire-fighting and washing stations
• watering installations, etc.
