Systems and methods for minimizing pressure fluctuations within a pumping apparatus are disclosed. These plate-shaped elements comprise a finger-shaped tongue as well as a rectangular plate, which are constructed in one piece. The TWIs may be formed prior to forming the RDLs, after forming the RDLs, or substantially simultaneously to forming the RDLs. End plates having at least one inlet port and at least one outlet port are located on either end of the rotor. Also, the distribution is verified to ensure all package dependencies are included.
