OEM Rexroth A4VTG 71 A4VTG90 Hydraulic Piston Pump Parts Uchida Excavator | Tonkee®

At the core of the A4VTG 71 A4VTG90 pump is its axial piston design.

Axial piston pumps are known for their high efficiency and compact size, making them suitable for applications where space is limited, such as in excavators. The axial piston configuration ensures a smooth flow of hydraulic fluid, resulting in precise control and enhanced overall performance.

One of the notable features of the A4VTG 71 A4VTG90 pump is its variable displacement capability. This means that the pump can adjust the volume of fluid it displaces per rotation, allowing for dynamic control of the hydraulic system. Variable displacement pumps are particularly valuable in excavators as they enable operators to optimize hydraulic power based on the specific requirements of the task at hand, improving efficiency and reducing energy consumption.

The pump is designed to operate under high pressure conditions, delivering the necessary power to drive the hydraulic components of the excavator. This is crucial in heavy-duty applications where substantial force is required for digging, lifting, and other excavation tasks. The robust construction of the pump ensures durability and longevity, even in demanding working environments.

Uchida excavators, known for their reliability and performance, benefit from the integration of the Rexroth A4VTG 71 A4VTG90 pump.

The compatibility between the pump and the excavator's hydraulic system is essential for seamless operation and optimal performance. The pump's design takes into consideration the specific requirements of excavator applications, offering a reliable and efficient solution for hydraulic power transmission.

In terms of specifications, the A4VTG 71 A4VTG90 pump is characterized by its displacement, pressure rating, and rotational speed capabilities. The displacement refers to the volume of fluid the pump can displace in one rotation, typically measured in cubic centimeters per revolution (cc/rev). The pressure rating indicates the maximum pressure the pump can handle without compromising its integrity. Rotational speed defines the speed at which the pump operates, typically measured in revolutions per minute (RPM). These specifications are crucial for ensuring that the pump meets the performance requirements of the Uchida excavator.

Regular maintenance and proper care are essential for maximizing the lifespan and performance of the Rexroth A4VTG 71 A4VTG90 pump. This includes monitoring fluid levels, checking for leaks, and following the manufacturer's guidelines for service intervals. By maintaining the pump in optimal condition, operators can ensure the reliable operation of the Uchida excavator and minimize downtime.
