Use For Doosan DX360LCA-7M Excavator Hydraulic Pump 400914-01154 A8VO200D2/63R1

Product Specification

The Doosan 360-7M hydraulic pump, model A8VO200D2/63R1-NZN05F021X-S, is part of the Rexroth A8VO series of swashplate-type variable displacement dual piston pumps. Below is a summary of key information:

Technical Parameters

• Displacement Range: 200 ml/rev (specific models may support a wider adjustment range)

• Pressure Rating: Rated 35 MPa, peak 40 MPa

• Control Mode: Supports LA0/LA1 dual-mode split power control, allowing independent adjustment of power for both piston assemblies

• Integrated Functions: Built-in auxiliary gear pump, relief valve, and PTO (Power Take-Off) expansion interface

Application Features

• Designed for construction machinery, such as the Doosan 360-7M and other large excavators, meeting precise power matching requirements under heavy-duty operating conditions.

• Utilizes load-sensing control technology to dynamically adjust pump output flow, reducing energy consumption (approximately 25% more efficient than conventional pumps) and minimizing hydraulic system heat generation.

Installation & Maintenance

• Installation Requirements: Requires a flexible coupling with high shaft alignment accuracy (concentricity deviation ≤ 0.1 mm, tilt angle < 1°).

• Maintenance Guidelines: Recommended use of ISO VG46 anti-wear hydraulic oil with a cleanliness level of NAS Class 7. Regularly monitor oil temperature, pressure pulsation, and piston wear.
