Factory & FAQ
VG 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.
The VG Series Gear Pump is widely used in construction machinery, agricultural equipment, forklifts, dump trucks, hydraulic power units, and industrial hydraulic systems. It is suitable for medium and high-pressure hydraulic transmission applications.
The VG Series offers multiple displacement options, including:
VG0: 8–28 ml/r
VG1: 25–63 ml/r
VG2: 80–160 ml/r
Different displacements can meet various flow and pressure requirements.
The VG Series supports both rotation directions:
R = Clockwise rotation
L = Counterclockwise rotation
Rotation direction is viewed from the shaft end of the pump.
The pump provides different shaft configurations, including:
Straight key shaft
SAE spline shaft
Customized shaft options may also be available according to customer requirements.
The VG Series is compatible with several hydraulic fluids, including:
Mineral hydraulic oil (HLP)
Waterborne polymer solutions (HFC)
Biodegradable hydraulic oil (HEES)
HFD-U hydraulic fluids
Different sealing materials such as NBR and FKM are available for different oil types and working conditions.
Recommended operating temperature ranges are:
Standard hydraulic oil: -10°C to +80°C
Special hydraulic oil: -10°C to +50°C
Ambient temperature: -20°C to +60°C
Standard mounting: ISO 3019/2 or SAE flange
Rotation direction: right-hand (clockwise)
No radial or axial load should be applied to the shaft
Proper installation is critical for performance and durability.
They are widely used in:
CNC machine tools
Injection molding machines
Hydraulic power units
Industrial automation systems
Press machinery
VG 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.
