Gear Pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the high-precision pump body and shaft from moisture and environmental damage.
Custom Cartons or Crates: Individual reinforced packaging with shock-absorbent inserts for single pumps, and sturdy wooden crates for bulk or tandem pump orders to ensure safe handling.
Documentation: Includes technical data sheets, installation guides, and quality inspection certificates.
Delivery time depends on the specific model, port configurations, and destination but typically ranges from 1 to 4 weeks from the order date.
