1.1 Applications
The pump is suitable for clear water, condensate, water/glycol mixtu-
res up to a ratio of 35 % glycol as well as other liquids free from mine-
ral oil and without abrasives or long-fibred substances. Specially suited
for use in conjunction with rain water utilization.
The main areas of use are in water supply installations, as a boiler
feed pump, in process technology, in cooling water systems, in fire
extinguishers and in washing and sprinkler installations.
