Material Used as Description
PVC Pipes, valves, 󹪝t‐
tings and hoses
Use is not permitted.
Hoses  Reduce the use of hoses to a minimum (device connection). Must
not be used as the main pipe for the whole system. Recommenda‐
tion: EPDM hoses with an electrical resistance>10
9
Ω (e.g. Sem‐
per󹪞ex FKD supplied from Semperit or DEMITTEL; from PE/EPD,
supplied from Telle).
Gaskets Pipes, valves and
󹪝ttings
Use of Viton, AFM34, EPDM is recommended.
Hose connections Transition
Hose-pipe
Secure with clips conforming to DIN 2817, available e.g. from the
Telle company.
The following recommendation applies in order to achieve an optimum motor heatsink
(enclosure) lifetime:
• Engineer a closed cooling circuit with cooling unit manufactured out of stainless steel that
dissipates the heat through a water-water heat exchanger.
• All other components such as cooling circuit cables and 󹪝ttings manufactured out of ABS,
stainless steel or general construction steel.

You can also use equivalent products from other manufacturers.
Responsibility for the properties of third-party products resides with the plant manufacturer.
Consider the following pressure conditions when designing the cooling circuit.
Permissible pressure
• De󹪝ne the working pressure based on the 󹪞ow conditions in the supply and return pipes of
the cooling circuit.
