Principle of Operation
LAKOS Separators are designed specically 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 aect 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 proles 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 prole) or skirt (vertical prole).
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 overll the separator’s collection chamber, substantially aecting 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 eective 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 specic 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.
