Dispenser Cgntaininent Sumps <br />Specifying Dispenser Sumps <br />Dispenser Sumps are installed directly under a product dispenser, providing a <br />means of secondary containment for the dispenser and associated plumbing. <br />They also provide a means of surface access to the flexible piping connections. <br />Two types of dispenser containment sumps are used with the GeoFlex Piping <br />System. The first is the 'Shallow Dispenser Sump' which can be used with <br />both suction and pressure piping systems providing the 'Liquid Interstitial <br />Monitoring System" is used in the pressure piping system. The second is the <br />'Deep Dispenser Sump' used primarily for pressure piping systems which are <br />mn in series and do not use the "Liquid Interstitial Monitoring System <br />Refer to th9 "Dispenser Directory' within the Environ Products Price List to <br />select the appropriate Dispenser Sump model. <br />Dispenser Sump Applications <br />Dispenser Sumps used with Georlex piping will involve two types of <br />installation applications. The first is a "Junction Application" which occurs <br />only in pressure piping systems routed "in -series" (from one dispenser to the <br />next). This application uses the Tee Fitting to interconnect one flexible pipe <br />section to the next as well as branching off to the dispenser. <br />Shallow Dispenser Sumps <br />These lower profile dispenser sumps have a <br />total height of 19 inches, permitting the GeoFlex <br />Pipe to exit out of the Dispenser Sump at a very <br />high elevation which is ideal for suction piping <br />systems requiring slope back directly to the tank. <br />They may also be used in pressure piping <br />systems that are run in series and use the <br />'Liquid Level Monitoring System'. <br />There are two types of Shallow Dispenser <br />Sumps available. The upper illustrations show <br />the 'stepped-oul' version used mostly for <br />conventional pressure type dispensing units. <br />The lower illustrations show the 'non -stepped' <br />Shallow Dispenser Sump which is used typically <br />with suction type dispensing units. Available <br />soon. <br />Deep Dispenser Sumps <br />These higher profile dispenser sumps have total <br />height of 30 inches permitting the GeoFlex Pipe <br />to exit out of the Dispenser Sump at a very low <br />elevation which is ideal for pressure piping <br />systems requiring slope back indirectly to the <br />tank. Also recommended for use with pressure <br />piping systems run in series which do not use the <br />'Liquid Level Monitoring System'. <br />These Dispenser Sumps are height adjustable to <br />accommodate piping fall requirements between <br />all containment sumps. <br />Junction Applications <br />an <br />Pi <br />a <br />The second application is called a "Terminating Application" which occurs <br />under the dispenser located at the and of a pressure piping system routed <br />"in -series" or under all dispensers for suction piping systems. This <br />application uses the Elbow Fitting attached to a rigid riser pipe, or the <br />Geoflex Connectorto Interconnect the flexible pipe section to the dispenser. <br />FIFil01F <br />Nlur PIpF <br />Terminating Applications <br />J <br />Rigid <br />R1- Plpe <br />
