JS200 excavators hydraulic pump 215/11278

The 215/11278 is a part number for a hydraulic pump used in JCB JS200 and JS210 excavators. It is a main hydraulic pump, also known as a main hydraulic gear pump or axial piston pump, responsible for providing pressurized hydraulic fluid to power the excavator's various functions, such as lifting the arm, moving the bucket, and turning the tracks.

Here's some information about the 215/11278 hydraulic pump:

Manufacturer:

The 215/11278 hydraulic pump is likely manufactured by Kawasaki Heavy Industries, based on the Kawasaki part number format. Kawasaki is a well-known manufacturer of hydraulic components for heavy machinery.

Applications:

The 215/11278 hydraulic pump is primarily used in JCB JS200 and JS210 excavators, but it may also be compatible with other models or applications.

Functions:

The main function of the 215/11278 hydraulic pump is to convert mechanical energy from the excavator's engine into hydraulic pressure. This pressurized fluid is then distributed to various hydraulic actuators throughout the excavator to control its movement and perform work functions.

Key Specifications:

Displacement: The displacement of a hydraulic pump refers to the volume of fluid it can move per revolution. The specific displacement of the 215/11278 pump is not readily available, but it is likely in the range of 50 to 100 cc/rev (cubic centimeters per revolution).

Pressure: The maximum pressure rating of the 215/11278 pump is also not explicitly stated, but it is likely in the range of 300 to 400 bar (4,351 to 5,880 psi).

Maintenance:

Regular maintenance of the 215/11278 hydraulic pump is crucial for ensuring the excavator's optimal performance and longevity. This includes:

Oil Changes and Filter Replacement: Changing the hydraulic oil and filter regularly according to the manufacturer's recommendations is essential to prevent contamination and maintain proper lubrication.

Fluid Level Checks: Regularly checking the hydraulic fluid level and ensuring it is within the specified range is important to prevent cavitation and damage to the pump.

External Inspection: Inspecting the pump for leaks, loose connections, or visible damage is crucial for early detection of potential issues.

Troubleshooting:

If you experience problems with the hydraulic system of your JCB JS200 or JS210 excavator, the 215/11278 hydraulic pump could be the culprit. Common symptoms of a faulty hydraulic pump include:

Loss of power or weak hydraulic performance

Erratic or uncontrolled movements

Noisy operation

Visible leaks

Replacement:

If the 215/11278 hydraulic pump needs to be replaced, it is essential to use a genuine Kawasaki replacement part or a high-quality equivalent from a reputable manufacturer. Non-genuine or low-quality parts can compromise performance, reliability, and safety.

Safety Considerations:

Hydraulic systems operate at high pressures and can cause serious injuries if not handled properly. Always follow safety procedures when working on hydraulic systems, including:

Depressurizing the system before performing any maintenance or repairs.

Wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and sturdy footwear.

Consulting qualified technicians for complex procedures.
