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.

Certifications & Quality Assurance

Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
