DESCRIPTION & WORKING PRINCIPLE

The 6650678 Hydraulic Gear Pump is a high-volumetric-efficiency external gear pump designed to withstand severe mechanical stress, extreme pressure cycles, and dusty construction environments.

Featuring a balanced, compact aluminum and cast steel construction, it utilizes two intermeshing gears to displace precise amounts of fluid per revolution. Driven directly by the engine's output shaft, this single gear pump generates consistent hydraulic power, preventing pressure loss or flow cavitation during demanding loader functions.

TECHNICAL SPECIFICATION

Engineered to exact factory specifications, this pump guarantees seamless integration with your existing hydraulic lines without requiring system modification.

KEY FEATURES & ADVANTAGES

• OEM Direct Compatibility: Built exactly to swap out faulty original pumps on major Bobcat legacy models seamlessly.

• Anti-Cavitation Performance: Optimized internal distribution plates prevent fluid trapping, resulting in quiet operation and reduced thermal buildup.

• Heavy-Duty Sealing System: Fitted with high-temperature Nitrile/Viton oil seals to prevent pressure drops and leaks under intense industrial applications.

• Cost-Efficient Alternative: Delivers identical hydraulic flow, pressure thresholds, and lifetime performance as the original part at an affordable price point.
