JHP3 Series Hydraulic Gear Pump | JHP3100, JHP3125, JHP3160 | SL50W Wheel Loader Pump

JHP3 Series High-Performance Hydraulic Gear Pumps for SL50W Wheel Loaders

Product Overview: The JHP3 Series is a heavy-duty hydraulic gear pump specifically developed for 5-ton wheel loaders such as the SL50W. As the heart of the loader’s hydraulic system, this series provides powerful and steady oil flow for boom lifting, bucket tilting, and steering circuits. This range covers the complete lineup from JHP3100 to JHP3160. Engineered with a high-strength split cast-iron housing, these pumps are designed to withstand instantaneous impact pressures during extreme excavation tasks, ensuring maximum operational efficiency and stability.

Key Technical Advantages:

• Heavy-Duty Construction: Built with specialized wear-resistant cast iron for superior fatigue strength, capable of enduring thermal shocks from frequent directional changes and high-pressure relief cycles.

• 100% Plug-and-Play Replacement: Strictly manufactured to match OEM installation standards for SL50W and mainstream 5-ton loaders. Standard rectangular flanges, involute splined shafts, and flanged ports ensure seamless compatibility.

• Efficient Axial Pressure Compensation: Utilizing patented floating side-plate compensation technology, maintaining volumetric efficiencies over 93% even at a continuous pressure of 20 MPa, significantly speeding up the loader’s work cycle.

• Superior Sealing Performance: Equipped with premium high-pressure oil seals and heat-resistant O-rings to prevent external leakage in dusty environments, extending maintenance intervals.

• Target Applications: Working/Steering pumps for SL50W Wheel Loaders, mining machinery hydraulic systems, heavy-duty truck-mounted cranes, and industrial HPU.
