Product details

A4VG125DA2D2/32R‑NSF02F071DP Hydraulic Piston Pump

Product Overview

A4VG125DA2D2/32R‑NSF02F071DP is a high‑pressure hydraulic piston pump, the core power component for engineering machine. This hydraulic pump supplies pressurized hydraulic oil for the complete hydraulic system, delivering reliable power for travelling, slewing, boom and bucket actions of construction machinery. It is available as original replacement spare unit when the existing pump suffers wear, pressure drop or internal leakage.

Technical Specifications

- Part Number: A4VG125DA2D2/32R‑NSF02F071DP

- Type: Hydraulic piston pump

- Displacement: 125 cc/rev

- Series: A4VG

- Working Pressure: High‑pressure operation for heavy‑duty circuits

- Control Mode: Variable displacement

- Application: Construction engineering machine

- Medium: Standard anti‑wear hydraulic oil

Working Principle

This variable‑displacement hydraulic piston pump converts mechanical rotational energy into hydraulic pressure energy. Inside the pump housing, the rotating cylinder block and piston assembly generate pressurized flow. It adjusts output flow according to machine load requirements, feeding each branch circuit of the hydraulic system. Continuous and stable oil pressure guarantees smooth movement under heavy‑load, impact‑prone construction‑site conditions.

Key Advantages

1. Variable displacement design, good power adaptability, reduces energy consumption for the whole hydraulic system.

2. Robust internal friction pairs, low internal leakage, maintaining high working efficiency under long‑time continuous operation.

3. Excellent pressure‑holding performance, effectively avoids machine weak action, slow response and insufficient power.

4. Precise manufacturing, strong shock‑resistance, suitable for complex and harsh construction working environment.

5. Standard installation dimensions, high interchangeability, convenient for on‑site disassembly and overhaul.

Application Scope

Mainly fitted for large‑scale engineering machine including excavators, concrete mixers, road rollers and other heavy‑duty construction equipment. As the heart of the hydraulic system, this hydraulic piston pump directly affects the working efficiency and service life of the whole machine.
