Storage & logistics
Storing high-pressure pumps for the OM611 109 HP requires protection from humidity, extreme temperatures, and physical shocks to maintain their condition. Keep units in their original packaging or sealed plastic bags with desiccant packs to prevent corrosion. Store them in a climate-controlled environment, away from direct sunlight or sources of vibration, such as heavy machinery. For bulk orders, use sturdy shelving with dividers to prevent contact between pumps, and label each batch with the remanufacturing date and OEM reference for easy retrieval.
