-Type: Variable axial piston pump (commonly used in CAT medium-sized excavators).
-Displacement: Depending on the model, it is usually within the range of 100-200 cc/rev (depending on the actual model).
-Working pressure: The high-pressure side can reach 34-35 MPa (approximately 5000 psi), matching the design requirements of CAT hydraulic system.
-Material: High strength cast iron shell, wear-resistant alloy plunger, ensuring durability.
