PF4 Series Gear 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 PF4 Series Gear Pump is widely used in construction machinery, agricultural equipment, industrial systems, and material handling equipment, providing stable hydraulic power for lifting, steering, and actuation systems.
The PF4 pump typically supports a maximum continuous pressure of 250 bar (3625 psi), with some models allowing lower pressures depending on displacement.
The PF4 Series offers a wide displacement range, typically from 0.37 to 2.01 in⊃3;/rev (6–33 cc/rev), meeting different flow requirements.

The PF4 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.
