2CB-4.2/1.0 Log Splitter Hydraulic Pump 2 Stage Log Splitter Pumps

The 2CB-4.2/1.0 Log Splitter Hydraulic Pump is a two-stage hydraulic gear pump designed for log splitters, compactors, and press-type applications. It features a dual-stage operation, combining a high-volume, low-pressure stage (4.2 cubic inches per revolution) for rapid cylinder extension and a low-volume, high-pressure stage (1.0 cubic inch per revolution) for powerful splitting, achieving pressures up to 3000 PSI. Typically constructed with a cast iron or aluminum housing, it ensures durability and efficiency, operating at speeds up to 3600 RPM.

The log splitter hydraulic pump is ideal for small to medium engines (5–15 hp), delivering flow rates around 11–16 GPM. Its compact design allows direct coupling to gas engines or electric motors, with standard inlet/outlet ports (e.g., 1” NPT inlet, 1/2” NPT outlet) and a 1/2” or 5/8” drive shaft. This pump enhances cycle times and performance in demanding wood-splitting tasks.

Key Features of 2 Stage Hydraulic Log Splitter Pumps

What Size Hydraulic Pump for Log Splitter?

• 5 GPM Log Splitter Pump: This pump is suitable for small, lightweight log splitters used for splitting softwoods like pine or cedar with diameters under 10 inches. It requires a modest engine (around 4-5 HP) and provides slower cycle times, typically 15-20 seconds, making it energy-efficient for casual users with low-volume splitting needs. Ideal for homeowners with small fireplaces or occasional use, but it may struggle with harder woods or larger logs.
• 7 GPM Log Splitter Pump: A 7 GPM pump is appropriate for small to medium log splitters handling logs up to 12 inches in diameter, like soft to medium hardwoods. Paired with a 5-6 HP engine, it offers cycle times around 12-18 seconds. This pump balances efficiency and power for occasional use, but it’s less suited for heavy-duty tasks or frequent splitting of dense woods like oak.
• 8 GPM Log Splitter Pump: Designed for medium-duty log splitters, an 8 GPM pump works well with 5-7 HP engines, splitting logs up to 14 inches, including some hardwoods. Cycle times range from 10-15 seconds, providing decent speed for regular home use. It’s a cost-effective choice for users needing more power than smaller pumps without requiring large engines, though not ideal for commercial tasks.
• 9 GPM Log Splitter Pump: A 9 GPM pump suits medium log splitters for logs up to 16 inches, including mixed hardwoods like maple. Requiring a 6-8 HP engine, it delivers cycle times of 9-14 seconds. This pump is versatile for frequent home use or small-scale firewood production, offering a good balance of speed and force, but may be underpowered for very dense logs.
• 11 GPM Log Splitter Pump: Ideal for medium-duty log splitters, an 11 GPM pump pairs with 5.5-6 HP engines, handling logs up to 18 inches, including hardwoods like oak. Cycle times are around 10-13 seconds, making it efficient for regular firewood processing. It’s a common choice for commercial splitters due to its reliability and compatibility with standard setups.

• 13 GPM Log Splitter Pump: This pump is suited for medium to heavy-duty log splitters, requiring a 6.5-9 HP engine. It handles logs up to 20 inches, including tough hardwoods, with cycle times of 8-12 seconds. Perfect for frequent users or small commercial operations, it offers faster splitting than smaller pumps but requires a robust engine to avoid stalling.
• 16 GPM Log Splitter Pump: A 16 GPM pump is designed for heavy-duty log splitters, needing an 8-11 HP engine. It splits logs up to 24 inches, including dense hardwoods, with cycle times of 7-10 seconds. Ideal for high-volume firewood production or commercial use, it provides fast cycles but demands a powerful engine and larger hydraulic system.
• 22 GPM Log Splitter Pump: Suited for high-performance log splitters, a 22 GPM pump requires an 11-13 HP engine and handles large logs (up to 30 inches) of any wood type. Cycle times are 6-8 seconds, making it excellent for commercial operations. It ensures rapid splitting but needs a robust engine and hydraulic components to handle the high flow rate.
• 28 GPM Log Splitter Pump: This pump is for industrial-grade log splitters, requiring 15+ HP engines. It splits massive logs (over 30 inches) with cycle times of 5-7 seconds, ideal for high-volume commercial use. It delivers maximum speed and power but requires a heavy-duty engine, large hydraulic tank, and robust hoses to manage the high flow and pressure.
