25VQ Series Vane Pump, 17 Ring Size, 7/8 Straight Keyed Shaft, Outlet Opposite Outlet, CW Rotation

Match the key identifiers: it is a 25VQ series single vane pump with a 17 ring size, 3.37 in³/rev displacement, and a 7/8 straight keyed shaft. Rotation is clockwise, the port layout is outlet opposite inlet, mounting is a 2-bolt SAE B flange, and the ports are SAE 4-bolt flange style with a 1-1/2 inch inlet and 1 inch outlet. If your old unit lines up on those points, it is the same fit style.

Rated right at 3,000 PSI max, this pump handles the pressure demands you'd see in dump truck hydraulics without issue. It's built for high-pressure, high-speed service, and the 25VQ series has a track record in exactly that kind of application. Flow comes in at 25.5 GPM with 3.37 cubic inches per rev displacement, so you're getting solid output alongside that pressure rating. Buna-N seals are standard, which hold up well in typical hydraulic fluid environments.
