The glanded pumps of the IP-E (in-line) / DP-E (double) series are
meant to be used as circulation pumps in building services.
They may be used for:
• Hot water heating systems
• Cooling and cold water circulation systems
• Industrial circulation systems
• Heat carrier circuits
Typical installation locations are technical rooms within the building
with other domestic installations. Installing the device directly in
other used rooms (residential and work rooms) is not intended.
Outdoor installation is not permitted for this series.
CAUTION! Risk of material damage!
Impermissible substances in the fluid can destroy the pump. Abra-
sive solids (e.g. sand) increase pump wear.
Pumps without an Ex rating are not suitable for use in potentially
explosive areas.
• The correct use of the pump/installation also includes following
these instructions.
• Any other use is considered to be incorrect use.
