Manual

Maintenance/Purging

1. LAKOS Separators must be purged regularly. The over-accumulation of separated

solids will overfill the separator’s collection chamber, substantially affecting

performance and causing undue 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. 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 (SRV) is therefore recommended. The SRV-816 or SRV-833

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 (10 micron

recommended) can be cleaned and reused or simply replaced. Consult your

LAKOS representative for details on the solids recovery vessel and accessories.

c. 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. The Automated Ball Valve (ABV) and Electric

Fail-Safe Valves (EFS) are electric actuated ball valve assemblies with timer

controls to allow for the adjustment of the purge frequency and duration based on

a job specific application. The EFS is a battery backup style failsafe actuator that

will ensure closure of the valve even if there is a loss of power to the controller.

Consult your LAKOS representative for details.

3. eHTX 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 effective

solids evacuation.

5. To determine the necessary ABV or EFS purging frequency, purge often at first 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 fill the collection chamber.

Consult your LAKOS representative for specific 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. Heat tracing and

insulation can also be used to keep liquid from freezing in the separator and causing

damage.
