CBK-2 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.
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.
