Storage & logistics

For B2B buyers, storing remanufactured high-pressure pumps for the OM642 320 CDI 224 hp requires a climate-controlled environment to prevent seal degradation and corrosion. Units should be kept in their original packaging until installation, with desiccant packs added if storage exceeds three months. Rotate stock based on expiration dates (if provided) to ensure the oldest pumps are used first, and avoid stacking crates to prevent pressure points on the seals. Always inspect incoming shipments for transit damage before accepting delivery.
