Water cooling
The turbopumps HiPace 800 P with TC 400 have water cooling as standard equipment.
●
In case of increased backing pressure (> 0.1 hPa) and/or operation with high gas
throughputs, either air or water cooling may be used.
●
Generally use water cooling if the ambient temperature is > +35 °C.
Cooling water requirements
Connecting to a cooling water system
Insert hoses for the water cooling fore- and return-line as far as they will go in one
cooling water connection each.
Recommendation:
install dirt trap in the fore-line.
