The casing assembly includes an inlet casing having first and second inlet ports, an inlet casing coupling port, and an inlet fluid passageway providing fluid communication between the first inlet port, the second inlet port, and the inlet casing coupling port. The casing assembly further includes an outlet casing having an outlet port, an outlet casing coupling port, and an outlet fluid passageway providing fluid communication between the outlet port and the outlet casing coupling port. The outlet casing coupling port is removably coupled to the inlet casing coupling port. The sleeve is disposed in the inlet fluid passageway of the inlet casing.
