It features SAE 16 inlet and SAE 12 outlet ports for a standard, compatible connection with common hydraulic lines. The sturdy iron casing with a power-coated finish resists rust and impact, helping to extend service life in demanding environments typical of trucks, log splitters and tailgate lifts.
PTO Dump Pump Hydraulic (National Drivetrain)
This direct-mount C Series pump provides high-capacity performance, delivering 49 GPM at 1800 RPM with a CCW air shift design and a 7/8″ 13-tooth spline shaft. It supports up to 2400 RPM for demanding dump applications. A pre-mounted air shifter cylinder simplifies installation, while heavy-duty bearings and seals ensure reliability under heavy workloads.
EBUY 21.2GPM Hydraulic Pump
The EBUY model mirrors the 21.2 GPM class with 540 RPM and 2500 PSI capacity. It uses SAE 12 outlet and SAE 16 inlet ports for straightforward installation and fluid compatibility. The iron housing with a durable finish resists rust and impact, ensuring long service life in trucks, log splitters, and scissor lifts.
RYFT 11 GPM PTO Pump
This compact option focuses on 11 GPM with 540 RPM and 2500 PSI, offering SAE 12 outlet and SAE 16 inlet ports. The robust iron case and powder-coated finish provide durability for lighter-duty PTO tasks like smaller log splitters or tailgate lift operations, while preserving mounting compatibility with standard fittings.
Bestauto 21.2GPM Hydraulic Pump
The Bestauto 21.2 GPM variant combines high flow with a 540 RPM speed, delivering up to 2500 PSI. It uses SAE 12 outlet and SAE 16 inlet ports for standard fitment. A rugged cast iron body with a power-coated finish provides resistance to rust and impact, targeting heavy-duty use in trucks, dump trailers and log splitters.
Bestauto 16.6GPM Hydraulic Pump
This option emphasizes 16.6 GPM at 540 RPM with 2500 PSI capacity. It includes SAE 12 outlet and SAE 16 inlet ports for easy compatibility with standard hydraulic hoses. The durable iron housing and powder-coated finish promote longevity in demanding conditions common to trailers and log splitters.
Buying Guide: Key Purchase Considerations
- Flow rate and pressure: Higher GPM and PSI support faster lifting, quicker dumping and more powerful operation. Choose a pump that matches the hydraulic cylinder or motor on your equipment.
- Inlet/outlet ports: Ensure SAE 12 outlet and SAE 16 inlet ports align with your system fittings to prevent leaks and reduce modifications.
- Mounting and shaft compatibility: Verify direct-mount options or shaft spline compatibility (commonly 7/8″ 13-tooth) to fit your existing hardware without adapters.
- Construction quality: Look for cast iron or steel housings with rust-resistant finishes for durability in outdoor or dusty environments.
- Duty cycle and reliability: Consider units with robust seals, bearings and relief valve testing for continuous operation in dumping or lifting tasks.
- Installation ease: Pre-mounted shifters or easily accessible mounting studs simplify installation and alignment with hydraulic lines.
- Brand and support: Established brands often offer better parts availability, documentation and warranty.
- Application fit: Match the pump to your specific vehicle or machinery (log splitters, trucks, trailers) and ensure compatibility with the hydraulic pump system architecture.
The models above provide a range of flow rates, mounting options and durability levels to cover common PTO-driven applications. When selecting, balance flow and pressure with the load requirements of your equipment and the space available for mounting the pump.
