Buyer’s Guide: What to Consider

Choosing the right PTO hydraulic pump involves key factors like flow rate, mounting, and shift type. Here’s what to consider.

• Flow Rate (GPM): Higher GPM means faster lifting. For dump trucks, 49 GPM at 1,800 RPM is standard for efficient operation.
• Mounting Type: Direct mount attaches directly to the PTO, while remote mount allows flexible placement away from the transmission.
• Shift Mechanism: Air shift offers remote cab control; cable shift provides manual engagement. Choose based on your truck's setup.
• Pressure Rating: Look for at least 2,500 PSI working pressure. Higher ratings like 3,000 PSI ensure reliable performance under heavy loads.
• Shaft and Ports: Ensure the shaft spline count and size match your PTO. Common is 7/8-inch 13-spline; ports should be 1-inch NPT for secure connections.

Conclusion

Selecting the best PTO hydraulic pump for your dump truck depends on your specific needs. For direct mount with air shift, the National Drivetrain or ATRACYPART models excel. If you prefer cable shift, the World American and National Drivetrain options offer reliable manual control.

Consider your truck’s PTO setup, whether you need bi-directional flow, and your preferred shift method. Any of these five pumps will provide the hydraulic power you need for efficient dumping operations.
