It replaces the Cummins OE numbers 5511748 and 4329470, and is fitted to Cummins ISB 6.7, ISC 8.3, ISL 8.9 and ISX 11.9 and 15 litre engines from 01\/2010 onwards. Supplied new in the original sealed Bosch box, made in the Czech Republic, and covered by a 1-year manufacturer warranty.\u003c\/p\u003e\n\u003cp\u003eThe supply module is the pump unit of the SCR aftertreatment circuit. It draws diesel exhaust fluid from the tank through the INLET connection, filters it, and delivers it under pressure through the OUTLET connection to the dosing module, which injects it into the exhaust upstream of the SCR catalyst. A diaphragm pump, an integrated filter, a pressure sensor and a reverting valve set are combined in one heated housing. In the Denoxtronic 2.2 system a throttle in the return path holds the circuit at roughly 9 bar, and when the engine is switched off the reverting valve changes the flow direction so the module pumps the fluid back to the tank through the BACKFLOW connection, emptying the lines before the fluid can freeze and crystallise.\u003c\/p\u003e\n\u003cp\u003eAlso known internationally as: AdBlue Supply Module \/ DEF Pump \/ Urea Pump (EN), AdBlue Fordermodul \/ Harnstoffpumpe (DE), Module d'alimentation AdBlue \/ Pompe a uree (FR), Modulo di alimentazione AdBlue \/ Pompa urea (IT), Modulo de alimentacion AdBlue \/ Bomba de urea (ES), Modul de alimentare AdBlue \/ Pompa de uree (RO) -
