Komatsu Pumps Guide
Komatsu pumps are used across hydraulic, cooling, lubrication, fuel, injection, and support systems throughout a wide range of Komatsu equipment. This master hub is designed to keep customers inside a guided pump ecosystem: first understand the pump category, then move into deeper pump-type resources, then into model-based pump hubs, and finally toward the correct part number.
This page is not intended to replace the Komatsu parts book. Instead, it helps narrow the search faster by connecting pump type, machine family, and model-level pump guidance in one place. The Komatsu parts book for the exact machine serial number remains the final authority for fitment.

How This Pump Hub System Works
Use the pump-type guides to understand what kind of pump you need. Then move into the model-based guides to review example pump references associated with your machine family. Once you have a likely part number, use the site search to go directly to the relevant product page or continue cross-checking against the parts book.
Some part numbers shown throughout the hub system may be stocked products and others may be quote-based references. That allows the pump ecosystem to support both direct sales and research-driven parts requests.

Need Help Confirming a Pump?
If you are researching a Komatsu pump and are not fully sure which part applies, gather the machine model, serial number, and any visible pump number before reaching out. That information can be used to guide you toward the correct pump and quote options.
For final confirmation, always verify against your Komatsu parts book for the exact machine serial number.
