Shop GEAR PUMP for KOMATSU PC200-6 | Partsdic®

The gear pump used in the Komatsu PC200-6 is a positive displacement pump that utilizes the meshing of gears to pump hydraulic fluid.

It consists of two intermeshing gears, namely the drive gear and the driven gear. These gears are housed inside a casing with tight tolerances to create a sealed chamber. As the gears rotate, the fluid is trapped between the gear teeth and the pump casing, creating a pressure difference that forces the fluid to move from the pump inlet to the outlet.

One of the essential specifications of the gear pump is its displacement, which determines the volume of fluid delivered per revolution of the gears. The Komatsu PC200-6 gear pump typically has a displacement of around 42 to 45 cubic centimeters per revolution (cc/rev). This displacement value ensures an adequate flow rate to meet the hydraulic demands of the excavator's various functions.

Another critical specification is the maximum operating pressure of the gear pump. The Komatsu PC200-6 gear pump is designed to withstand high pressure, typically up to 250 bars or 3,625 pounds per square inch (psi). This high-pressure capability allows the excavator to perform heavy-duty tasks with ease.

The gear pump also features an integrated pressure relief valve, which safeguards the system from excessive pressure buildup.

The relief valve ensures that the pressure remains within the acceptable range and protects the pump and other hydraulic components from damage.

The efficiency of the gear pump is an important consideration as well. The Komatsu PC200-6 gear pump is designed to minimize internal leakage and improve overall efficiency. This efficiency helps optimize the performance of the excavator while reducing energy consumption and minimizing heat generation.
