The centrifugal-action separator can remove grit, sand, metal chips, fines, and other solids from liquids. It is perfect for use as a pre-filter to extend the life of fine filtration systems. These units require little or no maintenance, as there are no moving parts to wear out, or filter media to replace. The unit only requires a simple purging, eliminatingdowntime. It handles flows from 6 gpm and retention ratings to 50 micron.

INSTALLATION
The Separator should be installed in a near vertical position. The unit should be supported by means other than the inlet/outlet piping. First, connect the outlet of the unit to the outlet piping. Then install any supports, such as U-bolts or legs.
Next, connect the inlet piping to the inlet. Test for leaks and separation. The unit is now ready for operation.
PURGING AND MAINTENANCE
Separators must be purged regularly. If they are not, the separated solids will accumulate and overflow the collection area, affecting performance and contaminating effluent.
Users can manually, automatically, or continuously purge the collection area of the separator. Manual purging requires that the operator open a simple valve and empty the contents. Automatic purging can be done many different ways, but the simplest is setting a timer to open and close the valve, purging the contaminant on a regular basis. Continuous purging simply requires leaving a manual valve partially open at all time, letting the contaminant leak out at a controlled rate.
For best results, all purging should be done while the separator is in operation. Avoid purging “uphill,” which will result in buildup and clogging, affecting performance and operation.
Simple rules of maintenance include checking the purge valve regularly for clogging, scale, and buildup. If the unit is installed in an area where the ambient temperature is below freezing, the collection area and all purge piping should be kept from freezing while operating. If left in idle state under freezing conditions, the entire unit must be drained of liquid, and the collection area must be purged of solids.
HOW IT WORKS
Fluid enters the pressure vessel tangentially at high velocity. A centrifugal action is created, which forces the solids to separate and enter the sump, while the clean liquid exits up through the standpipe. The solids collect in the sump, and can easily be purged. The operation is so simple, it can be set to automatically purge on a timed interval.
