Komatsu series Hydraulic pump Accessories , piston Variable pumps Parts

Hydraulic pump accessories are essential for the proper operation of the pump and to ensure its longevity. Some common hydraulic pump accessories include:

1. Filter: A filter is used to remove impurities from the hydraulic fluid before it enters the pump. This helps prevent damage to the pump's internal components.
2. Seal: Hydraulic pumps are equipped with various seals to prevent fluid leakage. O-rings, mechanical seals, and dynamic seals are some of the most common types of pump seals.
3. Gasket: Gaskets are used to create a seal between the pump's housing and cover plate, preventing fluid leakage.
4. Bearing: The bearing supports the pump's rotating components and reduces friction, which helps improve pump efficiency and longevity.
5. Shaft: The shaft is the main component of the pump that transfers power from the motor to the pump impeller. It must be strong and durable to withstand the forces generated by the pump.
