.1 Uses
The pump is suitable for hot and cold water and other fluids free from
mineral oil and without abrasives or long-fibred substances. The main
areas of use are in water supply installations, as a booster pump, as a
boiler feeder pump, in industrial circulation systems, in process tech-
nology, in cooling water systems, in fire extinguishers and in washing
and sprinkler installations.

) When using a water-glycol mixture containing up to 40 % glycol (or media with a viscosity different to that of pure water, the flow data for the pump must be adjusted accord-
ing to the higher viscosity of the flow media, regardless of the percentage of the viscous matter. Only use branded goods with corrosion protection-inhibitors, follow manufac-
turer’s instructions.

) If other and also aggressive chemical fluids are to be pumped, be sure to follow catalogue instructions and first obtain the approval of WILO.
