Installation and service by qualified personnel only
1.1 Applications
The pump is suitable for drinking water, heating water, industrial water,
condensate, water/glycol mixtures up to a ratio of 40% glycol as well
as other liquids 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 feed pump, in industrial circulation systems, in pro-
cess technology, in cooling water systems, in fire extinguishers and in
washing and sprinkler installations.
Approval from the manufacturer must be obtained beforehand if corro-
sive chemicals are to be pumped.
