A pump assembly includes a pneumatic pump with a pump body having a discharge passage. The pump is operable to discharge compressed air through the discharge passage. The pump assembly also includes a cap adjacent the pump body and at least partially enclosing a first volume in communication with the discharge passage, and a casing at least partially surrounding the pump. The pump assembly further includes a second volume defined between the casing and the cap, the second volume in fluid communication with the first volume via an opening in the cap, and a casing outlet in fluid communication with the second volume. The pump assembly is configured such that the compressed air flows through the first volume and the second volume before being discharged from the casing through the casing outlet.
