How many inlet ports and how many discharge ports would you see in a balanced vane pump flex plate?

In a balanced vane pump design, the flex plate serves a crucial role in facilitating the movement of the vanes within the pump. Typically, a balanced vane pump features a unique configuration that incorporates multiple ports to manage fluid flow effectively.

The correct choice indicates that there are two inlet ports and two discharge ports. This design allows for improved efficiency and balanced loading of the pump components, which is essential to maintain optimal performance and reduce wear on the mechanism. The dual inlet and discharge setup helps in handling a higher volume of fluid while minimizing pressure variations during operation.

This configuration is beneficial for maintaining consistent flow rates and pressures, which is a key aspect of hydraulic systems that rely on balanced vane pumps. Therefore, understanding the port arrangement is essential for anyone working with hydraulic systems, as it directly impacts the pump's efficiency and reliability.
