These vane pumps are classified as fixed displacement, positive displacement pumps.
They operate based on the principle of using rotating vanes or blades that slide in and out of slots in the pump rotor. As the rotor rotates, the vanes create chambers of varying volume, drawing in hydraulic fluid at the inlet and pushing it out at the outlet. This design ensures a consistent flow of hydraulic fluid, making them suitable for various hydraulic systems.
The series consists of multiple models, each with different specifications. The numbers in the series (e.g., 2520VQ, 3520VQ) represent the specific model variations, and these models vary in terms of flow rates, pressures, and displacement volumes. For example, a 3520VQ pump will have different performance characteristics than a 4525VQ pump. The choice of model depends on the hydraulic system's requirements and the desired flow and pressure levels.
Flow Rate and Displacement:
One of the primary specifications of these vane pumps is their flow rate, which refers to the volume of hydraulic fluid they can deliver per unit of time. The specific flow rate varies among the different models in the series. Flow rates can range from several gallons per minute (GPM) to over 100 GPM, making them suitable for both low-flow and high-flow applications.
The displacement volume refers to the volume of fluid displaced by the pump per revolution. Different models in the series will have varying displacement volumes, which can be chosen based on the application's requirements.
These vane pumps are designed to operate within a wide range of pressure levels.
The pressure rating for these pumps can vary significantly among different models in the series, with some pumps capable of handling pressures from 500 psi (pounds per square inch) up to 3000 psi or more. The choice of a specific model depends on the system's pressure needs, and it's essential to select a pump that can handle the operating pressure without issues.
Materials and Durability:
The 2520VQ, 3520VQ, 3525VQ, 4520VQ, 4525VQ, and 4535VQ series vane pumps are typically constructed from durable materials such as cast iron, aluminum, or steel. These materials are chosen for their resistance to wear and corrosion, ensuring a long lifespan for the pump. The choice of material may depend on the specific application and the compatibility with the hydraulic fluid used.
