Product Specifications

Typical Applications

Product Features

• CP3S3 common rail high pressure pump
• Radial piston pump construction
• Direct cross-reference with Doosan OE 400912-00277
• Designed for diesel common rail injection systems
• Suitable for selected DL08 engine configurations
• Common application reference for Doosan DX340 excavators
• Individual pump number verification supported before shipment

Customers should not select the pump only according to the machine model. Different DL08 engine versions may use different common rail pumps. The most reliable confirmation method is to compare the number on the existing pump with 0445020253, 0 445 020 253 or 400912-00277.

Important Order Confirmation

Before ordering, please provide at least one of the following:

1. Old pump number: 0445020253 / 0 445 020 253 / 400912-00277
2. Pump label or product photo
3. Engine model and serial number
4. Excavator model

This avoids confusion between different DL08 common rail systems.

Doosan DL08 Fuel System Note

Doosan DL08 spans several emission versions and more than one common rail fuel system. This page locks only the reliably confirmed relationship: 0445020253 / 0 445 020 253 / 400912-00277 → Doosan DL08 → DX340 → CP3S3 common rail pump. Other DL08 injectors, high-pressure pumps and common rail components are treated as related DL08 products only; they are not mandatory matched parts for 0445020253. Always confirm by the number stamped on the existing pump, the engine and the machine information.
