EcoVortec Advanced Centrifugal Filtration
EcoVortec Centrifugal Separators are installed on the pipe line after the pumping equipment and function with the same pressure as the system.
Separators have no moving parts, filters, mesh or cartridges to replace.
Centrifugal Separators require only periodic solids purges which are done without stopping the system, eliminating solids during the normal production process.
Acceleration Chamber Water enters the separator tangentially creating a circular flow.
Separation Chamber Centrifugal force keeps. Solids heavier than water on the periphery of the separator Central Vortex Returning water in the center of the separator is free of solids and flows upwards through the separator’s central vortex due to the cyclonic action generated by the separator.
Collection Chamber Gravity attracts solids to the bottom of the separator to be purged.

EcoVortec Centrifugal Separators are selected according to the flow rate. In general separators have an input / output diameter smaller than the line where they are to be installed. We recommend the use of conical reductions.
Verify that the installation point is optimal for particle removal and close to the solids deposit.
The foundation where the separator is to be installed has to meet standards according to its weight in function (see data).
To avoid turbulence at the input of the separator, straight pipe of at least 5 diameters in length should be installed. The separator´s input is always on the side and the output on the top; a centrifugal separator cannot work otherwise.
Be sure there are no foreign objects inside the unit before it is installed.
EcoVortec Centrifugal separators have pressure gauge ports (1/4 NPT) at the inlet and outlet. It is convenient to install pressure meters to monitor pressure drop. This should be between 0.35 and 0.85 kg/cm2 to ensure the correct flow for the separator´s function.
If the separator has a discharge directly to atmosphere pressure use a throttling valve at the end to check pressure.
The Purge of a Centrifugal Separator is Vital to its Function:
- - Choose a proper place where solids discharge and collection can be achieved. To avoid clogging, purge lines should not have any sharp turns or upward flow. Purge deposit should be as close as possible to the separator. To change direction, if needed, an ample ratio is recommended.
- - The purge should be performed before the collection chamber is full. The time used to fill this volume depends directly on the amount of solids in the liquid. The higher the concentration the shorter the purging period will be. This time can be calculated with the solids concentration and the flow rate.
- - If the solids concentration is too high or the time between purges is too short, a continuous bleed can be used at aprox. 2% of the flow. For best results use a pinch valve.
- - For a better evacuation of solids, purge the separator while in operation.
- - It is convenient to install a manual ball valve on the auxiliary purge for eventual inspection.
- - During the start up of the system, the separator can be purged every 30 min and the time adjusted according to the amount of solids purged. Be sure to purge the separator until clean water comes out to ensure a complete purge and to protect the purge valve.
- - A centrifugal separator is blocked when the purge valve is open and no fluid comes out, or very little (sometimes clear liquid). The auxiliary purge should then be opened, and the separator tapped while operating until solids start to purge. Reduce time between purges to prevent clogging.
Our automatic purge systems work purge cycles from10 minutes, to 30 hours with a purge time from 1 second to 1 minute or more according to your application.
We have diaphragm valves actuated by the systems pressure, or automatic valves with pneumatic or electric actuators.
