Hydro separator
548 series, 1" through 2" union connections
CALEFFI
Application
The hydraulic separator creates a zone with a low pressure loss, which
enables connected primary and secondary circuits to be hydraulically
independent of each other; the flow in one circuit does not create or
interupt flow in another. Hydraulically decoupling primary and secondary
circuits eliminates pump conflict.
Submittal Data 2909 NA — Issue Date 10/2018
Dimensions
Typical Specication
Furnish and install on the plans and described herein, a Caleffi Hydro
Separator
as manufactured by Caleffi. Each separator must be designed
with an epoxy resin painted steel body, 300 series stainless steel internal
baffle, preformed insulation, a ½" threaded thermometer pocket well front
center, a brass blowdown valve with garden hose connection and automatic
brass air vent isolated manually with service check valve. The separator
design must include sweat, press or NPT female connections with cast iron
union nuts. Each separator shall be a Caleffi model 548 series or approved
equal. (See product instructions for specific installation information.)

Hydraulic characteristics
The hydraulic separator should be sized according to the maximum
flow rate value at the inlet.The selected design value must be the greatest
required flow rate of either the primary circuit or the secondary circuit.
