pipe work is not recommended.
3.
Required static pumping head
from base of cooling tower
is indicated by static lift
dimension and piping friction
losses.
4.
When tower is equipped with
safety railing package, inlet
piping should be designed to
clear the railing. Adjust static
lift as required.
5.
For units installed on vibration
isolation rails (provided by
