V10 Series Vane Pump, 03 Ring Size, 3/4 Straight Keyed Shaft, NPT Ports, Outlet Opposite Inlet Port, CW Rotation

For dump truck hydraulics, 4.5 GPM at the rated conditions is on the lighter end but can work depending on your cylinder size and how fast you need the bed to raise. This pump displaces 0.6 cubic inches per revolution and is rated up to 4000 RPM, so your actual flow will depend on what speed your PTO or drive is running. Dump truck use is listed as a supported application, so the pump is built to handle that duty. Just make sure your system pressure stays within the 2500 PSI max and your hydraulic connections matches the 1 inch NPT inlet and half-inch NPT outlet before bolting it up.

This V10 series vane pump is well-suited for plastic injection molding, along with metal cutting, dump trucks, and wheel loader systems.

For replacement matching, yes, this pump crosses to V101P3P1A20 and also C1JZ50. The model here is a V10 series single vane pump with the 03 ring size, 0.6 in³/rev displacement, and a 4.5 GPM rated flow.
