Every hydraulic breaker has a heart — for the Krupp HM2000, that heart is the lower hammer part, Part No. 2265129. It’s the component that takes the brunt of every strike, cycle after cycle, absorbing pressure and impact deep inside the tool. Over decades of quarries, demolition sites, and construction projects, thousands of HM2000 units wore this part down until replacements became nearly impossible to find.
That’s where MERIT comes in.
While most suppliers have long given up on sourcing parts for this discontinued model, we’ve kept searching, testing, and stocking genuine components — because we know that behind every worn-out breaker is a crew waiting to get back to work. Part 2265129, the HM2000 Lower breaker part, is one of the toughest parts to track down on the market today. We currently have it in stock, inspected and ready for shipment.
If your Krupp HM2000 has gone quiet because of a damaged front head, don’t scrap the machine — reach out to MERIT. We’ll confirm fit, check compatibility with your unit’s serial number, and get your breaker back to full power.
