MULTIFUNCTION (4-IN-1)
HYDRAULIC SEPARATOR
PRODUCT FEATURES
High performance multi-function hydraulic separator
The Caleffi SEP4™ saves on system installation and maintenance costs with four high performance
functions combined into one device: hydraulic separation, micro-bubble coalescing air separation, dirt
separation and magnetic separation. Includes thermowell tap, pre-formed insulation jacket and easy-to-
use drain valve. Constructed of corrosion-resistant functional parts for a long, trouble free operating life.
Four functions combined into one device:
Minimizes components and labor costs for
system requiring primary/secondary piping.
Separate air and dirt separators not required.
Unique geometry and design:
Prevents pump conflict by hydraulically de-coupling
primary and secondary circuits. Preserves design
flow in all circuits.
Internal upper and lower mesh element:
Causes micro-bubbles to collect and coalesce
for efficient air separation. Deflects and collects
both ferrous and non-ferrous debris down to 5
microns size.
Anti-rotation/anti-vibration pinned oat:
Creates space between float and air vent wall to
prevent float hang-up from debris formation. Enables
needle valve to reliably vent out collected air.
Powerful neodymium rare-earth magnet:
Attracts ferrous impurities with 2 ½ times
the removal performance of a standard dirt
separator.
Additional value-added features:
Convenient union press, sweat and NPT connections,
½” thermowell tap, pre-formed insulation jacket and
easy-to-use drain valve.
