An apparatus for servicing a wellbore comprising a housing, high-pressure ports, high-volume ports, and a mandrel slidably positioned within the housing. The housing defines an axial flowbore and the mandrel defines a mandrel axial flowbore. The mandrel is alternatingly movable from a first position to a second position and to a third position. When the mandrel is in the second position, a route of fluid communication via the high-pressure ports is provided and a route of fluid communication via the high-volume ports is obstructed. When the mandrel is in the third position, a route of fluid communication via the high-volume ports is provided. The apparatus is transitionable from the second position to the third position without communicating an obturating member to the apparatus, without removing an obturating member from the apparatus, or combinations thereof.
