Typical Non-Pressurized Flow Center
Installation
Standing column ow centers are designed to
operate with no static pressure on the earth loop.
The design is such that the column of water in the
ow center is enough pressure to prime the pumps
for proper system operation and pump reliability.
The ow center does have a cap/seal, so it is still a
closed system, where the uid will not evaporate. If
the earth loop header is external, the loop system
will still need to be ushed with a purge cart.
The non-pressurized ow center needs to be isolated
from the ush cart during ushing because the ow
center is not designed to handle pressure. Since this
is a non-pressurized system, the interior piping can
incorporate all the above-mentioned pipe material
options (see interior piping), including PVC. The
ow center can be mounted to the wall with the
included bracket or mounted on the oor as long as
it is properly supported.
