1. General
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.

8
Motor power: see rating plate,
Maximum current: see rating plate,
Fluid temperature: –15 °C to 110 °C
with gaskets – EPDM
(KTW/WRAS),
–15 °C to 80 °C version with
with gaskets – VITON
Max. permissible working pressure: 10 bar,
Max. permissible inlet pressure: 6 bar,

Other voltages/frequencies and material properties are optional and/or
available on request.
When pumping viscous fluids (e.g. water/glycol mixtures) adjust the
pump data to allow for the higher viscosity.
Only use branded glycol mixtures with corrosion inhibitors and follow
the manufacturers instructions.
