YP10-0.8A2H2-L Shimadzu Compatible High Pressure Gear Pump 20.6MPa

Product Overview

The YP10-0.8A2H2-L, YP10-1.7A2H2-R, YP10-2.5D2D2-R and YP10-3A2D2-R models are high-pressure external gear pumps fully interchangeable with the genuine Shimadzu YP10 series. Featuring a high-strength aluminum alloy body, alloy steel gears, special alloy side plates and precision bushings, these units deliver high volumetric efficiency and low noise operation. Every pump undergoes 100% simulated duty-cycle testing to guarantee exact matching of mounting flanges (horizontal or diagonal 2-bolt), shaft end (woodruff key), ports (G-thread side or rear), rotation direction and performance curves with original Shimadzu units. Ideal for forklifts, construction equipment and compact industrial systems, they provide a reliable drop-in replacement that reduces spare-part costs and downtime.

Key Technical Advantages

1. High-strength aluminum alloy body combined with precision alloy-steel gears and special-alloy side plates maintains high volumetric efficiency and low internal leakage even at 20.6 MPa.
2. Optimized gear and flow-path design significantly reduces operating noise, making the pumps suitable for noise-sensitive mobile and indoor applications.
3. Full dimensional interchangeability with genuine Shimadzu YP10 series (flange, shaft, ports and rotation) verified by rigorous testing, enabling true drop-in replacement without structural modifications.
4. 100% simulated duty-cycle testing covering pressure, speed and flow curves guarantees factory performance matching the original units and minimizes field failures.
5. Ultra-lightweight design (only 0.6–0.7 kg) with high power density simplifies installation and improves overall system compactness.

Application Areas

Forklift hydraulic systems, construction machinery auxiliary circuits, agricultural equipment, material-handling machinery, compact industrial power units, aerial work platforms and other mobile or stationary systems requiring a compact high-pressure gear pump.

Expert Maintenance Tips

• Ensure precise shaft alignment using a flexible coupling; avoid applying radial or axial loads directly to the woodruff-key shaft end.
• Keep suction line diameter at least equal to the pump inlet, minimize length and fittings, and maintain inlet pressure within –0.02 to 0.1 MPa to prevent cavitation.
• On first start-up, set the system relief valve to the lowest setting, run at low speed under no load for several minutes to purge air, then gradually raise pressure to operating level.
• Use ISO VG32 hydraulic oil at 40 °C and maintain high fluid cleanliness; replace filters regularly.
• Periodically check shaft-seal condition and mounting-bolt torque (standard M8 bolts approx. 24.5–27.5 N·m); keep the seal area clean to extend service life.
