Replacement CCW grooved volute case — not a complete pump.
The Franklin XS439 CCW grooved volute case, part 305462035, is a service component for XS3x4-9 water truck pumps. It has counterclockwise (CCW) rotation and grooved connections, with a 4-inch suction and 3-inch discharge.
Use this case when servicing the matching grooved pump configuration. The volute and impeller must match the pump rotation; a clockwise case is not a substitute for the counterclockwise version. Confirm rotation from the shaft end and compare the connection style before ordering.
| Feature | Benefit |
|---|---|
| Grooved suction and discharge | Matches a grooved piping arrangement rather than an NPT-threaded connection. |
| Rotation-specific case | Choose the case that matches the installed impeller and pump rotation. |
