Axial Piston Variable Pumps Rexroth A4VSG

Rexroth Series Equivalent A4VSO A4VSG A10VO52/53 Series A10VSO A7VO A11vo A15vso A20vso High Pressure Hydraulic Oil Axial Piston Pump

Axial Piston Variable Pumps A4VSG series 1X and 3X

The A4VSG series axial piston variable displacement pump is specifically engineered for closed-loop hydrostatic drives. As a high-performance alternative to Rexroth A4VSG, it excels in high-pressure applications where precise control and compact design are critical. It features an integrated boost pump (charge pump) to replenish oil and provide pilot pressure, making it the heart of heavy-duty transmission systems.

Features:

1. Robust pump with very long service life
2. Low operating noise
3.Through drive for mounting of further pumps up to same nominal size
4.Flow direction changes smoothly when the swashplate is moved through the neutral position
5.Axial and radial load capacity of the drive shaft
6.Modular design
7.Visual swivel angle indicator
8.Short response times
9.Operation on HF-fluids under reduced operational data possible
10.Swashplate design

Typical Applications

Marine & Offshore: Winch drives, crane systems, and propulsion steering.

Industrial Machinery: Large forging presses, heavy-duty shunted drives.

Mining & Construction: Tunnel boring machines (TBM), crawler drives, and mobile drilling rigs.

All of HYLEMAN products are completely equivalent and interchangable with the original.

FAQ

Q: How do I identify the correct replacement model?
A: You need to check the Nameplate on the motor. Key information includes: Model Code,Displacement ,Shaft Type

Q: How does your pricing compare to the original brand?
A: We offer a significant cost advantage compared to the original manufacturer. As a high-quality aftermarket alternative, we eliminate the premium branding costs while maintaining rigorous manufacturing standards. You get the same robust performance and reliability at a much more competitive price point, helping you reduce your equipment BOM (Bill of Materials) costs.

Q: What is your standard delivery time?
A: Our standard delivery time is 15 to 30 days. We understand that project timelines are critical. Unlike the original brand, which may have unpredictable lead times or supply chain bottlenecks, we maintain a steady production schedule to ensure you receive your hydraulic components within this timeframe, allowing you to plan your production or maintenance schedules with confidence.

Q: Do you offer technical support for installation?
A: Absolutely. We provide comprehensive technical support to ensure a smooth installation process. If you have questions, our engineering team is ready to assist you to ensure the pump integrates perfectly into your hydraulic system.
