Product details

I. Product Overview

The A10VO28DFR1/31L hydraulic plunger pump is an axial piston variable-displacement pump with a swashplate structure from the Rexroth brand, specifically designed for hydrostatic transmission in open circuits. This pump features a flow rate proportional to the drive speed and displacement, and enables stepless variable displacement by adjusting the angle of the rotating swashplate, making it widely applicable in scenarios requiring precise control of the pump's output flow.

II. Product Features

1. Swashplate Structure: The swashplate design ensures a compact structure and ease of maintenance.

2. Axial Piston Design: The axial piston configuration enhances the pump's efficiency and durability.

3. Variable Displacement Control: Stepless variable displacement is achieved by adjusting the angle of the rotating swashplate, meeting flow demands under various operating conditions.

4. Low Noise Level: The pump generates minimal noise during operation, improving the working environment.

5. Low Pressure Pulsation: The pump delivers a steady output flow, reducing pressure fluctuations within the system.

6. High Efficiency: The pump's design ensures high energy conversion efficiency, reducing energy consumption.

7. High Cavitation Resistance: The pump exhibits excellent cavitation resistance, enabling stable operation in harsh working environments.

8. Universal Through-Shaft Drive: The pump's drive method is flexible, accommodating different drive systems.

III. Technical Specifications

• Model: A10VO28DFR1/31L

• Nominal Pressure: 32 MPa (also stated as 30 MPa in some cases, depending on the product batch or configuration)

• Operating Temperature: 30-90℃

• Applicable Medium: Hydraulic oil
