1. General

Installation and service by qualified personnel only
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
conjunction with rain water utilization.
The main areas of use are in rain water utilization systems, water
supply installations, in industrial circulation systems, in process
technology, in cooling water systems and in washing and sprinkler
installations.
Selfpriming pumps must not be directly connected to the public water
supply system.
