The applicator of claim 1, wherein the plurality of diverter passages, the pump channel, or both the plurality of diverter passages and pump channel can be blocked such that the adhesive cannot pass therethrough. 3. The applicator of claim 1, wherein the pump channel comprises a plurality of pump channels, wherein the fourth opening of each of the pump channels is in fluid communication with a respective one of the plurality of pump assemblies. 4. The applicator of claim 1, wherein the plurality of diverter passages comprises a first quantity of first openings that is different from a second quantity of second openings. 5. The applicator of claim 1, wherein each of the plurality of diverter passages extends along a linear axis from the first surface to the second surface. 6. The applicator of claim 1, wherein each of the plurality of diverter passages extends along a nonlinear axis from the first surface to the second surface. 7. The applicator of claim 1, wherein the flow diverter plate is removably received within the applicator. 8. The applicator of claim 1, wherein the flow diverter plate comprises a first piece and a second piece separable from the first piece. 9. The applicator of claim 8, wherein the first piece of the flow diverter plate defines a first portion of one of the plurality of diverter passages, such that the first portion extends from a front surface of the first piece to a back surface of the first piece, the second piece of the flow diverter plate defines a second portion of the one of the plurality of diverter passages, such that the second portion extends from a front surface of the second piece to a back surface of the second piece, and the back surface of the first piece and the front surface of the second piece engage when the flow diverter plate is assembled. 10. A method of diverting flow in an applicator, the method comprising: positioning a flow diverter plate in fluid communication with a pump assembly having an outlet and with a dispensing module having an inlet;flowing an adhesive out of the outlet of the pump assembly and into a first opening of a diverter passage defined within a body of a flow diverter plate;moving the adhesive through the diverter passage, the diverter passage including a second opening in fluid communication with the inlet of the dispensing module, such that the adhesive exits at the second opening of the diverter passage; andflowing the adhesive from the second opening of the diverter passage into the inlet of the dispensing module. 11. The method of claim 10, wherein moving the adhesive through the diverter passage includes moving the adhesive through a plurality of diverter passages, wherein at least some of the plurality of diverter passages are in fluid communication with each other. 12. The method of claim 10, further comprising moving at least a portion of the adhesive into another diverter passage after flowing the adhesive into the first opening of the diverter passage. 13. The method of claim 10, further comprising flowing the adhesive from a supply channel into a pump channel defined by the body of the flow diverter plate, the pump channel having a third opening in fluid communication with the supply channel and a fourth opening in fluid communication with an inlet of the pump assembly. 14. The method of claim 10, further comprising blocking the first opening, the second opening, or both, of the diverter passage such that the adhesive cannot move through the diverter passage. 15. The method of claim 10, wherein positioning the flow diverter plate in fluid communication with the pump assembly comprises selecting one flow diverter plate from among a plurality of flow diverter plates, each having a different flow pattern. 16. The method of claim 10, wherein positioning the flow diverter plate in fluid communication with the pump assembly comprises assembling the flow diverter plate from a first piece and a second piece. 17. The method of claim 16, wherein the first piece of the flow diverter plate defines a first portion of the diverter passage, such that the first portion extends from a front surface of the first piece to a back surface of the first piece, the second piece of the flow diverter plate defines a second portion of the diverter passage, such that the second portion extends from a front surface of the second piece to a back surface of the second piece, and the back surface of the first piece and the front surface of the second piece engage when the flow diverter plate is assembled.
