The Rehlko KDW1404 E530 sits in Rehlko’s KDW liquid‑cooled diesel range and delivers 18.8 kW (25.2 hp) at 3000 rpm, making it well suited to compact machinery that needs a capable, work-ready engine without moving into larger high-power packages. As a 4‑cylinder platform, the KDW1404 is often selected where smoother running characteristics and consistent performance matter in real-world duty.
For OEMs, the appeal is a well-established engine family that integrates cleanly into a wide range of equipment types, with a clear variant code for specification and procurement. For operators and service teams, it’s about predictable uptime and straightforward maintenance — backed by Rehlko’s documentation and long-term support ecosystem.
If you’re building this into a machine, the fastest way to ensure a clean install is to confirm your integration requirements up front — cooling layout, intake/exhaust routing, mounting arrangement, and electrical interfaces. Share those constraints and we’ll sanity-check that E530 @ 3000 rpm is the right match for the duty profile before you commit.

Applications

The Rehlko KDW1404 E530 is a great fit for compact industrial and mobile equipment that benefits from 3000 rpm operation and the smooth, consistent delivery of a 4‑cylinder diesel engine. Typical applications include compact construction and utility machinery, industrial power units, pumps, specialist OEM equipment, and other installations where packaging space is limited but dependable output is essential.
In many builds, the selection comes down to operating speed and the machine’s duty cycle. The E530 variant is particularly relevant where you want a clear 3000 rpm-rated engine specification for repeatable performance across builds or fleet standardisation. If you’re choosing between KDW1404 variants, we can help confirm the best-fit option by reviewing your target load profile and installation interfaces.
