Product Overview

The A4VSO series is a swashplate-type axial piston variable pump designed by Rexroth for open-circuit hydraulic systems, delivering high efficiency and reliability for heavy-duty industrial applications. It features a robust construction, wide displacement range, and multiple control options, making it ideal for high-pressure hydraulic drives. Our A4VSO pumps are 100% compatible with original Rexroth products, serving as a cost-effective replacement while maintaining the same performance and durability.

Core Features

Swashplate Design: Enables infinitely variable flow adjustment by changing the swashplate angle, meeting different flow requirements of hydraulic systems.
High Efficiency & Low Noise: Optimized internal structure reduces energy loss and operating noise, improving the overall efficiency of the hydraulic system.
Durable Construction: Adopts heavy-duty bearings and precision-machined components, ensuring stable operation under high pressure and long service life (≥10000 operating hours).
Versatile Control Modes: Multiple control options (constant pressure, constant power, manual, proportional) to adapt to diverse application scenarios and control requirements.
Through-Shaft Drive: Allows combination pump setup for multi-circuit hydraulic systems, saving installation space and reducing equipment costs.
Easy Maintenance: Modular design simplifies disassembly and assembly, convenient for daily inspection, maintenance and parts replacement.
Visual Indicator: Equipped with swashplate angle indicator, facilitating real-time monitoring of pump operation status.

FAQ

Q: What’s the difference between A4VSO and A10VSO hydraulic pumps?

A: A4VSO is designed for high-pressure (350bar nominal pressure) heavy-duty applications, with larger displacement range and stronger load-bearing capacity; A10VSO is suitable for medium-pressure (280bar nominal pressure) general industrial use, with smaller volume and lighter weight.

Q: Can the A4VSO pump use water-glycol fluid?

A: Yes, but it is only applicable to 180-355 size models, and the performance parameters (such as pressure and service life) will be slightly reduced. It is recommended to consult our technical team before use.

Q: What is the warranty period of your A4VSO pump?

A: The warranty period is 12 months from the date of delivery, covering manufacturing defects. Damage caused by improper use, installation or maintenance is not covered by the warranty.

Q: Do you provide samples?

A: Yes, we provide samples for testing. The sample delivery time is 3-7 days, and the sample fee can be deducted from the bulk order payment.

Q: Can you customize the pump according to our requirements?

A: Yes, we provide OEM/ODM customization services. You can provide the required displacement, pressure, control mode, mounting type and other parameters, and we will design and produce accordingly.
