Storage & logistics
Storing high-pressure pumps for OM651 engines requires attention to environmental conditions to preserve their condition until installation. Keep units in a dry, temperature-controlled space away from direct sunlight, as excessive heat or moisture can degrade seals and internal components. For garages, organize pumps by reference and engine compatibility to streamline retrieval during busy repair schedules. Avoid stacking units to prevent pressure on critical parts, and inspect packaging for damage upon arrival to address any transit issues promptly. If storing for extended periods, consider using desiccant packs in sealed containers to mitigate humidity risks, ensuring the pump remains ready for immediate use when needed.
