1.1 Applications
The pump is suitable for clear water, industrial water, condensate,
w
ater/glycol mixtures up to a ratio of 35 % glycol as well as other
liquids free from mineral oil and without abrasives or long-fibred sub-
stances. Specially suited for use in conjunction with rain water utilization.
The main areas of use are in water supply installations, as a boiler
f
eed pump, in industrial circulation systems, in process technology,
in cooling water systems, in fire extinguishers and in washing and
sprinkler installations.
