QT Internal 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.
1. What industries use the QT Internal Gear Pump?
The QT Internal Gear Pump is widely used in industries such as construction, agriculture, manufacturing, material handling, marine, and oil & gas. Its versatility makes it suitable for hydraulic systems in machines like tractors, forklifts, excavators, and more.
The QT Internal Gear Pump can typically handle a maximum pressure of up to 320 bar (4640 psi), depending on the specific model and configuration. This makes it ideal for high-pressure applications in heavy-duty machinery.
High Efficiency: It offers high efficiency in hydraulic fluid flow, leading to better overall performance in various hydraulic systems.
Compact Design: Its compact size ensures that it can be used in space-constrained environments.
Durability: The robust design and high-quality materials ensure long-term reliability and minimal maintenance.
The QT Internal Gear Pump commonly uses flange mounting, which ensures easy installation and secure attachment to the hydraulic system. Some models may also offer other mounting configurations, depending on the application.
The QT Internal Gear Pump offers a wide range of displacements to meet various hydraulic system requirements. Displacement ranges typically vary from as low as 0.5 ml/r to 7.8 ml/r, depending on the model (QT2, QT3, QT4, etc.).

The QT Internal 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.
