The Rear Cartridge houses elements that contribute to the pump's operation and performance. The Rear Cartridge incorporates a discharge port that allows the pressurized fluid to exit the pump and be directed to the desired hydraulic system. The discharge port is located opposite the inlet port in the Rear Cartridge. The rotor is a part within the rear cartridge. It features an eccentric profile and is responsible for driving the movement of the vanes. Attributes:• Ensure proper contact between the vanes and the rotor, maintaining optimal sealing and efficient fluid displacement by using Vane Spring• Part contains a pressure chamber where the fluid is compressed and pressurized. This chamber is formed by the interaction of the vanes and the rotor Applications:The Rear Cartridge used in the Vane Pump works in conjunction with the front cartridge to create the pumping action in a vane pump. As the rotor rotates within the rear cartridge, the vanes slide in and out of their slots in the front cartridge, creating variable chambers that draw in and discharge fluid.
