Flynsu 28 GPM Two Stage Hydraulic Pump

The Flynsu pump is designed for two-stage operation with 28 GPM in the first stage and 7.6 GPM in the second stage, making it a strong choice for fast wood splitting and other high-flow duties. Best for users who need quick actuator travel and a robust, durable build.
Why selected: Cast iron body and hardened steel gears support demanding environments. 4000 PSI intermittent, 3000 PSI continuous pressure rating aligns with typical log splitter specs. Needle bearing construction reduces friction and wear.
Best for: Wood processors and heavy-duty splitters that require rapid initial stroke and dependable performance. Choose this if you prioritize high first-stage flow and durable gears.
Caution: Ensure your engine rotates counterclockwise when viewed from the shaft side and provide 100% positive fluid supply to avoid pump damage. Requires about 15 hp or more for efficient operation.

HonHuCo 28 GPM 2-Stage Hydraulic Pump

HonHuCo’s pump targets users upgrading home wood splitters or small shops. The two-stage design provides a balance of speed and splitting force, with a 4000 PSI peak and 3000 PSI continuous rating. Best for affordable, robust performance without compromising duty.
Best for: Home wood splitters and small woodworking operations seeking reliable two-stage flow. Avoid if you require taller mounting flexibility or a different shaft arrangement.
Caution: Engine must rotate counterclockwise when viewed from the shaft; ensure a clean, full fluid supply to prevent premature wear.
Holdia 2 Stage Hydraulic Log Splitter Pump

Holdia is positioned for flexible installation, supporting vertical or horizontal mounting. This makes it well-suited for compact setups where space is constrained but high flow is still needed.
Why chosen: The pump delivers 28 GPM in the first stage and 7.6 GPM in the second, with a 4000 PSI intermittent/3000 PSI continuous rating. It uses a 5/8″ shaft and 3/16″ keyway, with 1″ NPT inlet and 3/4″ outlet. The design emphasizes reliability and mounting versatility.
Best for: Installers who need a versatile pump for varied orientations. Limitation: As with other two-stage pumps, proper fluid supply and mounting alignment are critical to prevent premature wear.
ToolTuff Direct 28 GPM 2 Stage Pump

ToolTuff Direct offers a straightforward two-stage pump with 28 GPM first-stage flow and standard 5/8″ shaft and 3/16″ keyway. It is a simple, dependable option for users who want a reliable upgrade without extra features.
Best for: Budget-conscious buyers needing a reliable two-stage setup. Limitation: The listing provides concise specs; verify compatibility with your system’s mounting and porting before purchase.
Tivora 28 GPM 2-Stage Hydraulic Pump

Tivora’s model is built to handle the pressure and duty of log splitters with a robust cast iron frame and needle-bearing components for reduced friction during operation. It includes a 5/8″ shaft, 1″ NPT inlet, and 3/4″ outlet, with a 4000 PSI intermittent rating and 3000 PSI continuous.
Best for: Industrial-style wood splitters and presses where consistent high-flow is needed. Choose this if you value a sturdy, cast-iron construction and smooth operation. Caution: Ensure correct orientation of motor rotation and a proper fluid supply to prevent damage.
BestParts 28 GPM 2-Stage Pump

BestParts provides a complete two-stage wood splitter pump with a cast-iron body and hardened steel gears. The unit uses a 5/8″ shaft, 3/16″ keyway, 1″ NPT inlet, and 3/4″ outlet. It delivers up to 4000 PSI intermittent and 3000 PSI continuous.
Best for: Users seeking a full kit that emphasizes durability and a straightforward mounting footprint. Limitation: Some listings emphasize basic features; confirm mounting compatibility with your setup.
Buying Guide: 28 GPM Two-Stage Hydraulic Pumps
- Flow and pressure needs: Match first-stage flow (28 GPM) with the required cylinder speed for your application, and verify the continuous PSI rating (commonly 3000 PSI) to ensure sustained performance.
- Mounting and shaft: Check SAE mounting compatibility, shaft diameter (5/8″), and keyway size (3/16″). Ensure inlet/outlet ports match your hydraulic system (usually 1″ NPT inlet and 3/4″ outlet).
- Mount orientation: Most models allow vertical or horizontal mounting, but confirm fluid pickup orientation and the need for a 100% positive fluid supply to avoid pump damage.
- Power requirements: Expect around 15 hp or more for efficient operation. Verify your power source and drive setup to avoid under- or over-revving the pump.
- Durability: Cast iron housings and hardened steel gears contribute to longevity under demanding workloads. Needle bearings help reduce friction and wear in moving parts.
FAQ
- What does 28 GPM mean in a hydraulic pump?
GPM stands for gallons per minute and indicates the maximum hydraulic fluid flow the pump can deliver. Higher GPM enables faster actuator movement for quicker cycles.
- Can I use a 28 GPM pump on a single-stage system?
These are designed as two-stage pumps; a single-stage setup may not utilize the first-stage flow efficiently. Confirm compatibility with your equipment’s valve and cylinder configuration.
- Is a 4000 PSI intermittent rating necessary for log splitters?
Many log splitter applications benefit from 4000 PSI intermittent rating, which provides higher peak capability during short bursts. Continuous ratings around 3000 PSI are typical for steady operation.
- What mounting considerations should I know?
Check for SAE mounting compatibility, shaft size (5/8″), keyway (3/16″), and inlet/outlet threading. Ensure the pump can be mounted in your desired orientation with a 100% reliable fluid supply.
- What maintenance is required for these pumps?
Regularly check fluid cleanliness, inspect seals and bearings, and ensure the system remains free of air. Follow the manufacturer’s guidance for lubrication and replacement intervals.
