Reverse return piping schematic
Conventional flow/return piping
The pressure characteristics of Solo were
designed to facilitate even flow sharing by
ensuring that the pressure drop at various
flow rates considerably exceeds the piping
friction loss.
Care must therefore be taken to ensure
that adequate pumping capacity exists to
guarantee adequate flow. A 6m head pump
is suggested, and approximately 6-8 Solo
units max per 22mm flow and return circuit
is recommended.It is suggested that
reverse return pipework be used where
possible.
The performance data must be derated as
outlined above if lower flow rates are opted
for.
Pipe connections to Solo are 15mm dia.
and space exists internally in the units to
allow for flow isolators if required
