Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 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.

Axial Piston Pump vs Radial Piston Pump FAQ

1. What is the main difference between axial and radial piston pumps?

The primary difference lies in the arrangement of pistons:

• Axial piston pump: Pistons are arranged parallel to the drive shaft.

• Radial piston pump: Pistons are arranged perpendicular (radially) around the shaft.

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.
