Applications
The 3PG Hydraulic Gear Pump is highly versatile and used in a wide range of industries and applications where efficient and reliable hydraulic power is required.
3PG Hydraulic 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 maximum pressure varies depending on the model, but the 3PG series can handle pressures up to 250 bar (3625 psi) in different configurations, with some models offering even higher pressure capabilities.
The displacement for the 3PG Hydraulic Gear Pumps ranges from 19.3 cm³/rev (1.2 in⊃3;/rev) to 77.2 cm³/rev (4.7 in⊃3;/rev), making them suitable for a wide variety of flow requirements.
The 3PG series is used across multiple industries, including construction, agriculture, industrial machinery, material handling, mining, oil and gas, and marine, among others.

The 3PG Hydraulic Gear 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.
