SEAL FLUSHING ARRANGEMENTSAll mechanical seals require flushing to lubricate the seal facesand maintain normal operating temperatures. Seals are normallyflushed with either a clean external fluid or by the liquid beingpumped. Fybroc Series 1500 pumps are furnished, as standard,with tapped glands for connection to the flush liquid or with theoptional configurations shown below.INTERNAL COVER FLUSHFybroc’s Internal Cover Flush option eliminates the need forexternal flushing of single mechanical seals from the pumpdischarge, which also eliminates the possible breakage ofexternal tubing and fittings.This option removes seal heat by circulating high pressureliquid internally through the drilled cover to the seal chamberand then recirculating this liquid back to the low pressure sideof the pump.HighPressureLiquidLowPressureLiquidFYBROC’S OPTIONAL FLUSH ASSEMBLYPACKAGEThe flush assembly* consists of the following items:1) Shut off valve and pressure gauge mounted on epoxy-coatedsteel bracket. Inlet side.2) Solenoid valve and flow meter/metering valve mounted onepoxy-coated steel bracket. Outlet side.3) Necessary tubing and fittings to pipe system to seal gland.*Note: The assembly is intended for use on pumps withdouble inside mechanical seals (Crane 8-1T, Flowserve RXO).Consult Factory for additional “special” configurations.The system is designed to operate as follows:1) Flush water is brought to the inlet side of the system andpiped away to a suitable drain on the outlet side.2) The normally closed solenoid valve is wired into the motorstarter controls and opens when the motor is energized.3) The inlet shut-off valve would remain open at all times andwould be used only when the system needed to be isolatedfor maintenance purposes.4) The flow meter/metering valve would be adjusted as necessaryto obtain a reading of 1 /4 - 1 /2 GPM.When properly installed and operated as referenced above, theflush system will ensure that the mechanical seal is operating in theproper environment and is being cooled and lubricated asrequired.8
