High-Quality Main Pump 272-6955 (2726955) - Cat320 Excavator Hydraulic Pump Assembly For Reliable Caterpillar Performance

Product Details of Caterpillar Excavator Hydraulic Pump

This hydraulic pump is specially designed for Caterpillar excavators to ensure efficient equipment operation and operational stability. As a core component, the caterpillar excavator hydraulic pump adopts variable hydraulic transmission technology, which accurately matches the power requirements of all Caterpillar excavator series. It can meet the needs of various working conditions such as heavy-duty mining operations and light municipal engineering, with a volumetric efficiency of over 90%. The hydraulic pump caterpillar complies with Caterpillar's original factory standards, using high-strength wear-resistant alloy materials and undergoing surface nitriding treatment. This extends the service life of the pump body by 30% and reduces maintenance costs. The cat 320 excavator hydraulic pump has undergone thousands of working condition simulation tests, and it is compatible with the hydraulic system of the Cat 320 excavator. It ensures flow stability under complex working conditions and provides guarantee for efficient operations.

1.Efficient Power Transmission: The caterpillar excavator hydraulic pump is equipped with a two-stage pressure regulating valve group, which automatically adapts to load changes. When excavating hard rock, the output torque is increased by 25%, significantly improving operational efficiency. The hydraulic pump caterpillar adopts a low-friction pair design, with a power response delay of ≤ 0.5 seconds, avoiding construction delays caused by power interruptions. It is compatible with anti-wear hydraulic oil (ISO VG 46). The cat 320 excavator hydraulic pump has an optimized internal oil circuit flow channel, which reduces along-the-way pressure loss, improves power transmission efficiency, and meets the main pump flow requirements of the Cat 320 excavator.?

2.High-Reliability Design: The caterpillar excavator hydraulic pump uses a combined structure of lip seal and dust seal to prevent hydraulic oil leakage. It is equipped with a 10μm high-precision filter element to filter impurities and protect internal components. The production process of the hydraulic pump caterpillar complies with the ISO 4413 hydraulic standard and has passed a 1.2-times rated pressure holding test, with a qualification rate of 100%. The cat 320 excavator hydraulic pump is additionally equipped with a forced heat dissipation oil circuit. When operating under high load, the temperature rise of the pump body is ≤ 40℃, reducing the failure rate by 40%.

?

The caterpillar excavator hydraulic pump is compatible with Caterpillar 312/315/320 and other series of excavators, and its interface conforms to the SAE J518 hydraulic connection standard. The hydraulic pump caterpillar adopts the original factory size design, which can be directly replaced without modifying the equipment, and the installation time is shortened to within 2 hours. The cat 320 excavator hydraulic pump is accompanied by an installation manual, which marks key torque parameters (bolt pre-tightening force: 80-85N·m), allowing even novice users to complete the installation efficiently.

The caterpillar excavator hydraulic pump is produced using a CNC machining center throughout the entire process, and has been inspected by a coordinate measuring machine, with a dimensional accuracy reaching IT7 grade. The hydraulic pump caterpillar provides a 12-month warranty period. If there are quality problems within the warranty period, free repair or replacement services will be provided. The cat 320 excavator hydraulic pump has an exclusive after-sales service channel to provide technical support.
