Magister Hydraulics Hydraulic Gear Pump
Displacement: 0.61 cubic inches. Rotation: Clockwise. Max RPM: 3500. This gear pump is designed for compact hydraulic applications where precise, reliable flow is needed. The cast iron flange and 5/8″ key shaft integrate easily with standard drives, making it suitable for small machinery or retrofit projects that require consistent displacement and predictable output.
VEVOR 8 Quart Hydraulic Power Unit
High-Powered Performance: A 12V, 1.6kW DC motor delivers up to 0.91 GPM with an 8-quart tank and 16-20 MPa oil pressure, reaching up to 3200 psi. Precision double-acting lifting distributes force evenly, and a built-in safety relief valve helps prevent overpressure. The unit arrives pre-assembled for quick setup and includes SAE#6 connectors for compatibility with common interfaces.
ATRACYPART H2136201 Hydraulic Pump
High Flow Performance: Delivers up to 15.3 GPM at 1000 RPM, ideal for lift mechanisms and plow controls. Durable cast iron housing with Teflon-coated bronze thrust plates provides thermal stability and abrasion resistance. A 7/8″-13 spline shaft ensures tight engagement with drive motors or PTOs, reducing vibration and wear for high-efficiency hydraulic performance.
VEVOR 8 Quart Dump Trailer Pump
Single-Acting Power Unit: This 12V hydraulic pump offers up to 0.91 GPM flow with a maximum relief pressure of 3200 psi. A robust build includes sealed components and a rust-resistant steel tank designed for heavy-duty daily use. Quick lifting and a built-in safety relief valve promote safer operation with fewer failures.
Bestauto 16 GPM Hydraulic Pump
16 GPM with 3600 RPM and 4000 PSI max pressure. This unit is designed to deliver high flow for demanding log splitting or heavy-duty hydraulic tasks. It uses a 1″ inlet, 1/2″ NPT outlet, and a 1/2″ shaft with a 3/8″ key, rotating clockwise. Aluminum housing provides resistance to rust and impacts for extended service life.
Gdrasuya10 13 GPM Log Splitter Pump
Two-stage hydraulic gear pump capable of 13 GPM at 1000 RPM with a maximum pressure around 3000 PSI. The 1/2″ shaft and standard 1″ inlet design suit a range of log splitters and heavy equipment. High-strength aluminum housing offers durability and resistance to rust, supporting reliable long-term use in demanding environments.
LCyindu 16 GPM Two-Stage Pump
Two-stage design with 16 GPM and 3600 RPM, max pressure around 3000 PSI. Made from high-strength extruded aluminum, the pump resists rust and high pressures. It features a 1″ inlet, 1/2″ NPT outlet, and a 1/2″ diameter shaft with clockwise rotation. This unit is intended for robust log splitter or similar hydraulic tasks requiring high flow and dependable performance.
AGKNX Log Splitter Build Kit
New Hydraulic Log Splitter Pump with 16 GPM at 3600 RPM, includes shaft, inlet/outlet ports (1″ and 1/2″ NPT), and mounting hardware. This kit aims at quick setup for a 1″ engine crankshaft connection, enabling faster operation and easier installation for DIY log splitter projects.
Buying Guide: Key Purchase Considerations
- Flow rate vs. application: Higher GPM means faster cycling for lifting and splitting, but may require more power and cooling. Match the flow rate to the workload and drive source capabilities.
- Pressure rating: Ensure the max relief pressure aligns with system requirements. Over-pressurization can damage seals and components; look for integrated relief valves and robust housings.
- Drive compatibility: Check shaft size, spline count, and rotation direction to fit motors, PTOs, or engines. Verify inlet/outlet thread types (NPT vs SAE) for hose and port fittings.
- Build material and durability: Cast iron housings are durable and good for heavy use; aluminum housings save weight but may require careful handling in rugged environments. Consider seals and corrosion resistance for outdoor use.
- Mounting and installation: Look for flange or bolt-mount options that fit your frame. Pre-assembled units save time, but kits offer customization for specific setups.
- Maintenance and serviceability: Access to replacement parts (seals, gaskets, bearings) and ease of disassembly influence long-term costs and downtime.
- Power source and efficiency: DC motors (12V) suit mobile setups, while AC or higher-voltage configurations deliver sustained performance for shop use. Consider efficiency ratings for energy savings.
- Safety features: Integrated relief valves, proper enclosure, and leak prevention measures reduce risk during operation and maintenance.
- Warranty and support: Check manufacturer warranty terms and availability of technical support for troubleshooting and parts.
Note: The products listed above are selected for relevance to an 8 GPM-oriented hydraulic workflow, including gear pumps and power units suitable for trailers, log splitters, and heavy-duty hydraulic tasks. Always verify compatibility with your specific system before purchase.
