    摘要: A pump assembly (100) having improved cooling for use in a selective catalytic reduction system is disclosed. The pump assembly comprises a pump housing (104) having a body portion (106) and a nozzle portion (108) extending from the body portion (106), a jacket (130) including a cavity (132) for receiving the pump housing (104), first and second ports (232, 230) for cooling fluid, and a flow guide (200) disposed between the jacket (130) and the pump housing (104). The cavity (132) includes a first compartment (220) for cooling fluid defined in part by the flow guide (200) and in part by the pump housing (104) and being in fluid communication with the first port (230); and a second compartment (224) for cooling fluid defined in part by the flow guide (200) and in part by the jacket (130). The first compartment (220) is in fluid communication with the second port (232) by way of the second compartment (224).
