Rexroth A8VO double hydraulic pump for Caterpillar excavator 330BL 345BII E322 E320B 133-8908 123-2235-06 311-9541 247-8975-01 123-2233-01

The Rexroth A8VO series is a variable displacement axial piston pump, and the double-pump configuration in the Caterpillar 330BL excavator serves as its core hydraulic power source. This compact, robust unit typically consists of a main pump and a smaller auxiliary pump (often a gear pump) on a common drive shaft, engineered for heavy-duty excavator duty cycles.

Key features include:
• Variable Displacement: The main piston pump automatically adjusts its swashplate angle to vary flow output based on system pressure and demand, optimizing efficiency and control.

• Load-Sensing Control: Often integrated to deliver precise, responsive flow matched to the operator's commands, reducing energy loss and heat generation.

• High Power Density: Designed for the high-pressure, continuous operation required in excavation, providing reliable power for the machine's implements, travel, and swing functions.

• Rugged Construction: Built to withstand extreme pressure spikes, contamination, and severe vibrations typical of earth-moving equipment.

In the CAT 330BL, this pump ensures powerful, smooth, and fuel-efficient operation of the hydraulic system, directly contributing to the machine's digging force, lift capacity, and overall productivity. Its reliability and serviceability are critical for minimizing downtime in demanding construction and mining environments.

Q1: What is the primary function of the Rexroth A8VO double pump in the Caterpillar 330BL?

A1: It serves as the core hydraulic power source for the entire machine. It generates the high-pressure fluid flow required to operate the excavator's main implements (boom, arm, bucket), its travel motors, and its swing system, directly enabling digging, lifting, and movement.

Q2: What key design features of the A8VO hydraulic pump make it suitable for the harsh operating conditions of excavators?

A2:The A8VO hydraulic pump is designed with a robust and durable structure, capable of withstanding extreme pressure peaks, high contamination, and severe vibrations. It is designed for high power density and continuous operation, providing reliable performance even under harsh conditions such as earthmoving and mining.

Q3:What is the price and delivery time of the A8vo hydraulic pump for Caterpillar excavator？

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
