Packing & Delivery

To ensure the safe delivery of variable piston pump and hydraulic motor, we utilize multiple layers of protective packaging. The pump is first sealed in a durable plastic bag to prevent moisture and contamination. Next, it is securely fixed within a reinforced plywood case to prevent movement and damage during transportation, given the heavy weight of the product. Finally, the plywood case, built to standard export specifications, provides sturdy protection suitable for international shipping.
