Product details

A JCB hydraulic gear pump is an essential component in the hydraulic systems of many JCB machines, such as excavators, telehandlers, and telescopic handlers. This type of pump works by converting mechanical energy into hydraulic pressure to drive hydraulic motors or cylinders.

Key Features:
1. Efficiency: JCB hydraulic gear pumps are designed for high efficiency, ensuring that they can deliver power effectively without significant losses.
2. Durability: They are built to withstand the harsh conditions typical in construction equipment, offering long service life.
3. Reliability: These pumps are known for their reliability, minimizing downtime and maintenance needs.
4. Versatility: They can be used across various models and applications within the JCB range, making them a versatile choice for different tasks.

• Key Parameters:

• Pressure Range: Low-pressure types (e.g., CB-B series, rated pressure 6.3 MPa) to medium-high pressure types (e.g., ZYB series for diesel/heavy oil, stable pressure).

• Media Compatibility: Mineral oil (ISO VG32-68), water-based hydraulic fluids, food-grade oil (H1 class); avoid chlorine/sulfur-containing corrosive media.

• Temperature & Viscosity: Operating temperature -10°C to +80°C, viscosity range 10-500 cSt (at 40°C); preheating required for low-temperature startup.

Structural Features & Operating Principle

• Structural Components: Composed of driving gear, driven gear, pump body, front/rear covers, shaft sleeve, and relief valve. Gears undergo heat treatment or nitriding for high hardness and wear resistance.

• Operating Principle: Sealed volume changes via gear meshing and rotation. In the suction chamber, gear disengagement increases volume to draw oil; in the pressure chamber, gear engagement reduces volume to discharge oil. The meshing line separates suction/pressure chambers for oil distribution.

• Leakage Control: Axial clearance accounts for 75%-80% of total leakage; compensated via floating shaft sleeves or elastic baffles. Radial unbalanced force mitigated by floating bearing installation or balance grooves.

Application Scenarios & Industry Cases

• Construction Machinery: Hydraulic drive systems (e.g., JCB excavator hydraulic steering/braking systems), loader working devices.
