Key:
1. Pump body: The pump body houses the internal components of the pump.
2. Impeller: The impeller is a rotating part that creates suction to draw in hydraulic fluid.
3. Vanes: The vanes are attached to the impeller and help to move the hydraulic fluid.
4. Outlet port: The outlet port is where the hydraulic fluid exits the pump.
5. Inlet port: The inlet port is where the hydraulic fluid enters the pump.
6. Relief valve: The relief valve helps to control the pressure of the hydraulic fluid.
7. Suction port: The suction port is where the hydraulic fluid is drawn into the pump.
8. Pressure port: The pressure port is where the hydraulic fluid exits the pump under pressure.
9. Drive shaft: The drive shaft connects the pump to the engine.
10. Bearing: The bearing supports the drive shaft and helps to reduce friction.
11. Seal: The seal helps to prevent hydraulic fluid from leaking out of the pump.
