1.1 Applications
The multistage selfpriming pump is suitable for clear or slightly muddy
water, industrial water, condensate, water/glycol mixtures up to a ratio
of 35 % glycol as well as other liquids free from mineral oil and without
abrasives or long-fibred substances. Specially suited for use in conjunc-
tion with rain water utilization.
The main areas of use are in rain water utilization systems, water
supply installations, in industrial circulation systems, in process tech-
nology, in cooling water systems and in washing and sprinkler
installations.
Selfpriming pumps must not be directly connected to the
public water supply system.
