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.

Applications

The A4VSO series hydraulic pump is widely used in various heavy-duty industrial fields, especially suitable for high-pressure, high-power hydraulic systems. Main applications include:
  • Metallurgy & Steel Industry: Forging presses, rolling mills, hydraulic presses, continuous casting machines.
  • Mining & Construction Machinery: Excavators, crushers, tunnel boring machines, concrete pumps, bulldozers.
  • Marine & Offshore Equipment: Ship hydraulic systems, deck machinery, offshore drilling platforms.
  • Ceramic & Refractory Industry: Hydraulic presses for tile, brick and refractory production.

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.
