A11V series variable displacement axial piston pump

Introduction: Powering the Machines That Move the World

In the modern landscape of heavy machinery, construction, mining, and industrial automation, the hydraulic pump stands as the beating heart of every mobile and stationary system. Among the most trusted and widely deployed hydraulic components in the world, the A11V series variable displacement axial piston pump has earned a reputation for exceptional performance, durability, and engineering versatility.

Shandong Feici Engineering Machinery Co., Ltd., headquartered in Jinan, Shandong Province, China, is a professional enterprise specializing in the supply, distribution, and technical support of hydraulic power components. With a strong focus on quality, reliability, and customer-centric service, the company offers the A11V variable displacement axial piston pump as one of its flagship hydraulic solutions — engineered to meet the rigorous demands of today's most challenging working environments.

What Is the A11V Variable Displacement Axial Piston Pump?

The A11V is a swashplate-type axial piston variable displacement pump designed primarily for hydrostatic drives in open-circuit hydraulic systems. It is widely recognized across the global hydraulic industry for its robust construction, high power-to-weight ratio, and adaptability to a broad spectrum of applications — from mobile working machines to stationary industrial equipment.

The "A11V" designation refers to the pump's core architecture: an axial piston design with variable displacement capability, meaning the output flow can be continuously adjusted from maximum to zero without stopping the drive. This makes the A11V an ideal choice for systems requiring precise flow control, energy-efficient operation, and responsive power delivery under fluctuating load conditions.

Key Technical Features and Design Advantages

1. High-Pressure Performance

The A11V series is engineered to operate at high pressures, making it suitable for heavy-duty applications where consistent power output is critical. The pump delivers reliable performance at elevated working pressures, with the ability to withstand peak pressure spikes during demanding operational cycles. This ensures sustained productivity even in the most punishing environments — from deep-pit mining operations to high-reach concrete pumping.

2. Wide Displacement Range

One of the standout features of the A11V series is its extensive range of displacement options. Available in multiple sizes — including 40, 60, 75, 95, 130, 145, 190, and 260 mL/r — the pump can be precisely matched to the power requirements of virtually any hydraulic system. This scalability allows engineers and system integrators to select the optimal configuration for their specific application, minimizing energy waste and maximizing operational efficiency.

3. Versatile Control Options

The A11V pump supports a comprehensive range of control mechanisms, providing unmatched flexibility in system design:

• LR — Power Control: Enables constant power output, automatically adjusting flow in response to pressure changes. This is ideal for applications where engine power must be optimized and protected from overload.

• DR — Pressure Control (Constant Pressure): Maintains a stable system pressure regardless of flow demand, making it perfect for systems with multiple actuators operating simultaneously.

• EP — Electro-Proportional Control: Offers fast, precise, and electronically adjustable flow regulation, enabling seamless integration with modern digital control systems and intelligent machine platforms.

• HD — Hydraulic Pilot Control: Provides a simplified, self-contained control solution that reduces system complexity and installation costs.

These control options can be externally adjusted even while the pump is in operation, offering real-time adaptability that enhances both safety and productivity on the job site.

4. 100% Through-Drive Capability

The A11V features a full through-drive design, allowing additional pumps — such as gear pumps or other axial piston pumps of the same size — to be mounted directly onto the rear of the unit. This 100% through-drive capability enables compact, multi-pump configurations that save space, reduce component count, and simplify hydraulic circuit design.

5. Optional Charge Pump (Impeller)

For applications requiring enhanced self-priming capability, the A11V can be equipped with an optional built-in charge pump (centrifugal impeller). This feature ensures reliable lubrication and cooling at high rotational speeds, significantly extending the pump's service life and reducing maintenance intervals — particularly important in continuous-duty applications.

6. Stepless Flow Regulation

The output flow of the A11V is directly proportional to the drive speed and can be steplessly varied between maximum displacement and zero. This infinitely variable flow characteristic provides smooth, precise control over hydraulic actuators, resulting in improved machine handling, reduced shock loads, and enhanced operator comfort.

Typical Applications

The versatility and ruggedness of the A11V pump make it suitable for a wide array of demanding applications, including but not limited to:

• Construction Machinery: Excavators, wheel loaders, bulldozers, and compact track loaders

• Concrete Equipment: Concrete pumps, mixer trucks, and placing booms

• Mining Equipment: Drill rigs, haul trucks, and underground loading machines

• Material Handling: Forklifts, cranes, and aerial work platforms

• Agricultural Machinery: Tractors, harvesters, and sprayers

• Industrial Systems: Press machines, injection molding equipment, and steel mill machinery

• Special-Purpose Vehicles: Fire trucks, mobile cranes, and military vehicles

Its proven track record in these sectors underscores the A11V's ability to deliver consistent, dependable performance across diverse operating conditions — from extreme cold to high ambient temperatures, from dusty construction sites to corrosive marine environments.
