Excavator gear pump PVD-2B-42 PC50MR-2 PC55 PC56 mini excavator parts


The gear pump is a critical hydraulic component in excavators, responsible for converting mechanical energy into hydraulic energy by generating fluid flow and pressure. It plays a vital role in ensuring the smooth operation of hydraulic systems in construction machinery. This article provides a comprehensive overview of excavator gear pumps, including their working principle, construction, functions, applications, and maintenance procedures.

  • Product Name: Hydraulic Gear Pump
  • Port: Huangpu
  • Standard: Standard
  • Model:PVD-2B-42
  • Part number:PC50MR-2 PC55 PC56

The main components of an excavator gear pump include:

3.1 Housing (Casing)

  • Made of high-strength cast iron or aluminum alloy to withstand high pressure.

  • Provides structural support and contains internal components.

3.2 Gears (Drive & Driven Gears)

  • Precision-machined gears with tight tolerances to minimize leakage.

  • Typically made of hardened steel or alloy materials for durability.

3.3 Bearings & Bushings

  • Support the rotating shafts and reduce friction.

  • Lubricated by the hydraulic fluid to enhance longevity.

3.4 Shaft Seal

  • Prevents hydraulic fluid leakage.

  • Common types include lip seals and mechanical seals.

3.5 Inlet & Outlet Ports

  • Allow hydraulic fluid to enter and exit the pump.

  • Designed to minimize flow resistance and cavitation.

4. Functions of Gear Pump in Excavators

The gear pump serves several essential functions in an excavator’s hydraulic system:

4.1 Fluid Flow Generation

  • Provides the necessary hydraulic oil flow to actuators (cylinders, motors) for movement.

4.2 Pressure Build-Up

  • Creates hydraulic pressure required for lifting, digging, and rotating operations.

4.3 Lubrication & Cooling

  • Circulates hydraulic oil to lubricate moving parts and dissipate heat.

4.4 Power Transmission

  • Converts engine power into hydraulic energy for efficient operation of attachments.
