M5100 Loader Hydraulic Gear Pump | M5100-A767ADTL17-6 | M3100 M7600 High Pressure

The M Series Heavy-Duty Gear Pumps from LIC Hydraulic are engineered for the most demanding mobile equipment environments. Covering the M3100, M5100, and M7600 series, these pumps feature high-strength cast iron construction for maximum durability. Model M5100-A767ADTL17-6 is a high-pressure solution preferred by manufacturers for loader lift and steering circuits. We guarantee 100% mechanical interchangeability and subject every unit to 100% full-load efficiency and pressure testing, ensuring stable performance at pressures up to $3500\text{ PSI}$ ($241\text{ Bar}$).

Technical Configuration Details

• Frame Sizes: M3100 (Compact), M5100 (Medium), M7600 (High-Flow).

• Construction: Two-piece or three-piece high-tensile cast iron housing.

• Pressure Rating: Up to $3500\text{ PSI}$ continuous operation.

• Mounting: SAE Standard flanges and shafts (splined or keyed).

• Efficiency: Advanced axial pressure compensation for high volumetric output.

Key Technical Advantages

• Rugged Cast Iron Housing: Unlike aluminum alternatives, the cast iron body prevents housing expansion under extreme pressure, providing superior structural integrity and longevity in construction sites.

• Precision-Finished Gears: Alloy steel gears are case-hardened and ground to precise tolerances, reducing friction and ensuring quiet, smooth operation.

• Pressure-Balanced Thrust Plates: Floating side plates automatically optimize internal clearances, maintaining over $90\%$ efficiency even as the pump ages.

• Heavy-Duty Bearing Support: Equipped with oversized needle bearings designed to handle high radial loads and frequent shock loading typical of loader applications.

Application Areas

• Wheel Loaders: Primary pumps for lift, tilt, and steering functions.

• Earthmoving Equipment: Auxiliary hydraulic circuits for excavators and graders.

• Mining & Quarrying: Reliable power for heavy-duty dump truck hoists.

• Industrial HPUs: Compact but powerful hydraulic power units requiring high-pressure gear technology.

Expert Maintenance Tips

• Priming Before Startup: Always fill the pump with clean hydraulic fluid before the first start. A dry start can cause immediate scoring of the thrust plates and gear teeth.

• Inlet Filtration: To protect the precision internal surfaces, ensure your system uses a high-quality suction filter. Cavitation caused by restricted inlets is the leading cause of premature failure in cast iron pumps.

• Alignment Accuracy: Verify the alignment between the pump shaft and the PTO. Misalignment creates excessive radial stress, which will lead to shaft seal leaks and internal bearing damage.
