An adhesive bin (10) for storing and moving adhesive particulate (14) to an adhesive melter (12) includes a supply hopper (16), a transfer pump (62) operable to generate a vacuum, and a shroud (94). The supply hopper (16) has a sidewall (20, 22, 24, 26) and defines an interior space (36). The transfer pump (62) extends through the sidewall (22) and into the interior space (36). In addition, the shroud (94) is connected to the sidewall (22) and extends into the interior space (36) and at least partially surrounds an inlet (82) of the transfer pump (62).
