Typical Non-Pressurized Flow Center
Installation
Standing column flow centers are designed to
operate with no static pressure on the earth loop.
The design is such that the column of water in the
flow center is enough pressure to prime the pumps
for proper system operation and pump reliability.
The flow center does have a cap/seal, so it is still a
closed system, where the fluid will not evaporate. If
the earth loop header is external, the loop system
will still need to be flushed with a purge cart.
The non-pressurized flow center needs to be isolated
from the flush cart during flushing because the flow
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
flow center can be mounted to the wall with the
included bracket or mounted on the floor as long as
it is properly supported.
