7Installation Operations and MaintanenceTrouble-Shooting Guidelines For Separator Installation1. Verify Actual Flow Rate:Use pressure gauges to indicate differential pressure and flow meter to verify flow rate.(Multiple pumps used to increase flow are installed in parallel (into common manifold);multiple pumps to increase pressure are installed in series (one after another).Flow meters should be installed prior to the separator. Flow meters installed after theseparator will indicate erroneous data.2. Plumbing Two Separators:Do not plumb two separators from two independent pumps into the same outlet headerwithout installing balancing valves on the discharge of each separator. The balancingvalves must be set to achieve a pressure loss across each separator that indicates a flowrate (according to that model’s published flow chart) equal to the flow rate anticipatedthrough the pump that feeds each separator.3. Verify Actual Inlet Pressure:Actual inlet pressure must be at least 15 psi (1.03 Bar). A minimum back pressure of 5psi (.34 Bar) must be created at the separator discharge. This may be accomplished viaprocess equipment, piping, or a valve. Unrestricted open discharge to a pit, sump,etc., will result in unacceptable performance. Be sure that no source of vacuum/suctionexists in the piping arrangement. If vacuum/suction exist (i.e. downward piping afterthe separator, pump suction installation, booster pump etc.), put a valve between theseparator and the suction source and pressure gauges on either side of the valve. Throttlethe flow until the pressure loss across the separator indicates the published flow ratewhich most closely resembles the anticipated flow rate through the separator.4. Vibration:Check installation piping inlet & outlet configurations (see appropriate product sheets formodel of separator installed). Mild vibration is possible in some installations and shouldbe considered normal. Excessive vibration is typically due to entrained air (use airvents), improper piping (follow the installation instructions) or system vibration(amplified at the separator).
