Specification

Product Details

Description

The 564-9801 (5649801) piston pump grouping is a core high-pressure fuel injection pump component designed for CAT 374, 336, 345 series excavators. It is responsible for providing stable high-pressure fuel supply to the engine injection system, serving as a key hydraulic part to ensure excavator power output and fuel efficiency. Manufactured with CAT’s original precision casting process, it features a gear-driven interface and pressure-regulating control module, compatible with the high-pressure injection system of excavator engines, and can directly replace original parts.

Advantage

Original Equipment Compatibility:Fully matches the engine interfaces of 374/336/345 excavators, requiring no additional adjustments for installation, with compatibility consistent with original parts.
High-Pressure Stability:Equipped with a precision piston structure, it can stably deliver high-pressure fuel (up to 1800bar) to ensure the atomization efficiency of the injection system.
Excellent Durability:The main body is made of high-strength cast alloy, withstanding high-frequency vibration and high-temperature working conditions of excavators, with a service life of 5000+ hours.
Intelligent Pressure Regulation:Built-in pressure-regulating module dynamically adjusts fuel pressure according to engine load, optimizing power output and fuel consumption.

Performance

Operating Pressure:Maximum output pressure of 1800bar, compatible with high-pressure common rail injection systems.
Drive Method:Gear-driven (compatible with the transmission structure of excavator engines).
Flow Parameter:Rated flow matches the fuel demand of 374/336/345 engines (specific value varies by model).
Operating Temperature:-40°C~120°C, resistant to extreme working condition temperatures.
