Principle of Operation
LAKOS Separators are designed specically to remove solids from liquids.
Each model is calculated for use within a prescribed ow range for
maximum performance and solids removal. Flow rates above and below the
recommended range may aect such performance. Upon tangential entry,
the liquid/solids are drawn through internal tangential slots and accelerated
into the separation chamber where solids heavier than the carrying liquid
are centrifugally separated and allowed to accumulate in the unit’s collection
chamber for eventual purging (see Page 5). The liquid (free of separable solids)
is then drawn to the vortex and up through the separator’s outlet.
Installation Instructions
1. LAKOS Separators are shipped on skids or in wooden crates. Support legs (22
½° low proles only) are detached. Lifting Lugs, located on the unit’s side
and/or anges, are provided for hoisting as necessary.
2. A suitable foundation is necessary to accommodate the LAKOS Separator’s
weight including liquid. Anchor bolts are recommended in the base of the legs
(low prole) or skirt (vertical prole).
3. Prior to installation, inspect the inlet/outlet/purge connections for foreign
objects incurred during shipping/storage.
4. Inlet/outlet pipe connections to the LAKOS Separator should be a straight
run of at least ve pipe diameters to minimize turbulence and enhance
performance.
5. Proper purge hardware and/or solids-handling equipment is required to ush
separated solids from the separator.
6. All LAKOS Separators operate within a prescribed ow range (Pipe size is not
a factor in model selection). Use appropriate hardware to match the inlet/outlet
size.

Installation Instructions (continued)
Grooved couplings are not included with the separator. Optional anged
connections are available upon request.
7. Inlet pressure to the LAKOS Separator must be at least equal to or greater
than the anticipated pressure loss through the separator plus 15 psi (1 bar) plus
whatever downstream pressure is required.
8. Pressure gauges are required at both the inlet and outlet of the separator in
order to monitor pressure loss and proper ow. If separator operates with an
open discharge, a valve should be installed to create a back pressure of at least
5 psi (0.3 bar).
9. Winterizing is important if the LAKOS Separator is to remain idle in freezing
temperatures. Drain liquid as necessary to avoid expansion of water to ice and
related damage.

Maintenance/Purging
1. LAKOS Separators must be purged regularly. Otherwise, the accumulation of
separated solids will overll the separator’s collection chamber, substantially
aecting performance and causing undo wear.
2. Several purging options are available and all may be performed while the LAKOS
Separator is in full operation.
a. Manual: A full-port, straight-through valve may be installed on the standard
purge opening and actuated manually as necessary to purge separated solids.
b. Automatic: The use of LAKOS Separators in a given application typically
implies the need for heavy or unusual solids removal. A LAKOS Auto-Purge
System is therefore recommended. Consult your LAKOS representative for
details on motorized ball valves and other systems.
c. Semi-Automatic: The use of LAKOS Separators in a given application typically
implies the need for heavy or unusual solids removal. A LAKOS Solids Recovery Vessel
System is therefore recommended. The SRV-816 allows for continuous purging of the
solids collected into a separate collection bag. Once the bag is full with solids, the bag
is emptied. The bag can be cleaned and reused, or simply replaced. Consult your LAKOS
representative for details on the solids recovery vessel and accessories.
3. HTX/HTH Separators feature standard purge outlets. Prior to start-up, the installation
of a manual valve on the purge is recommended so that this outlet may be serviceable
at any time for either supplemental purging or as a stand-by, should the primary purge
line ever require servicing.
4. Important: All purge hardware should be installed prior to any elbows or turns in the
purge piping. Avoid “uphill” purging, which can clog piping and hinder eective
solids evacuation.
5. To determine the necessary frequency, purge often at rst and calculate the proper
rate with regard to the actual volume of separated solids. Purge duration should be
long enough to evacuate the purge chamber of solids. Frequency of purge should not
exceed the time it takes to over ll the collection chamber. Consult your LAKOS
representative for specic recommendations regarding your application.
6. When operating in sub-freezing temperatures, be sure to protect the separator’s
collection chamber and all purge line piping from freezing.

Maintenance Recommendations
LAKOS recommends periodic inspections of the separator to keep performance
at an optimum level.
Full Faced Flange Gasket or Victaulic Gaskets should be checked for leaks and
replaced as necessary. Gasket should be replaced at disassembly of separator.
Main Barrel Seal should be replaced when disassembly of separator is required.
Hand Hole Clean-out. Hand Hole should be removed to inspect the collection
chamber for unwanted build up. Inspection should be conducted monthly or
when shutdown is convenient for access.
Hand Hole Gasket, inspected for leaks and change as necessary.
Separator Slots should be inspected during facility pipe inspection is required.
Inspection of slots is recommended when separator performance is suspect.
Slots should be checked for obstruction and wear.
Note: Visual inspection of the separator should be conducted once a month.
Visual inspection should also include observing the inlet and outlet gauges
on the separator. This inspection will indicate the pressure drop across the
separator. The pressure drop and actual ow rate can be compared to the
product brochure to determine if the separator is operating within its expected
performance range. Automatic purge or manual purge should be checked for
leaks and operation. Purge valve seats or diaphragms should be changed as
necessary.
