CBHY-GF pumps are typically packaged securely to prevent damage during transit. The packaging includes:
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.
1.What type of pump is the CBHY-GF?
CBHY-GF is an external hydraulic gear pump designed for stable fluid power transmission.
2. What is the pressure range of CBHY-GF pumps?
Rated pressure is up to 25 MPa, with maximum pressure up to 28 MPa depending on model.
3. What displacement options are available?
Common displacement options include 25, 28.2, 32, and 36 mL/r for the fore pump section.
4. What equipment uses CBHY-GF gear pumps?
They are widely used in construction machinery, tractors, forklifts, and hydraulic power units.
5. Does the pump support different shaft types?
Yes, key shaft and spline shaft options are available depending on application needs.
6. Can CBHY-GF pumps support clockwise and counterclockwise rotation?
Yes, both rotation directions are available.
7. What hydraulic oil is suitable for this pump?
Standard anti-wear hydraulic oil is generally recommended.
8. Can you provide OEM or replacement models?

CBHY-GF 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.
