Гидронасос AP2D36 для экскаватора Hitachi ZX60

The AP2D36 serves as the "power heart" of this series of compact excavators. It features a highly efficient combined design:

Piston section (variable displacement): Handles high-flow, high-pressure excavation tasks; it automatically adjusts via a load-sensing mechanism to ensure smooth, precise operation.

Gear section (fixed displacement): Typically functions as a pilot pump or auxiliary pump, supplying constant pressure and flow for control circuits, swing motor brake circuits, or dozer blade operations.

Technical Highlights:

Compact size: Specifically designed to fit the smaller engine compartments of ZX60/70/75 models; lightweight and easy to install and maintain.

Balanced reliability: While not an ultra-high-pressure system like those found in mining-class machines (e.g., PC3000), its design is highly durable, capable of withstanding the frequent operational cycles and cold-start stresses typical of compact excavators.

Agile response: Operators of machines in this weight class place a premium on "feel"; the AP2D36 delivers responsive performance that aligns perfectly with joystick inputs, enabling fine, precise control.
