JCB 20925328 K3V63DTP

The JCB 20925328 K3V63DTP is a Kawasaki K3V63DTP axial piston hydraulic pump used in JCB JS130 excavators. Let's break down the information

20925328 This could be a part number or identification code for the specific hydraulic pump used in JCB excavators. It's common for manufacturers to use alphanumeric codes to identify their products. Without more context or specific information about the pump's application, it's difficult to determine the exact meaning of this code. However, it's  unique to this particular pump model used in JCB excavators.

K3V63DTP

K3V This is a specific model designation for a hydraulic pump manufactured by Kawasaki Heavy Industries. The K3V series is a family of axial piston pumps known for their reliability, efficiency, and high power density. These pumps are widely used in various mobile and industrial machinery applications.

63 This likely indicates the pump's displacement in cubic centimeters per revolution (ccrev). A larger displacement means the pump can deliver more hydraulic fluid per revolution, which is crucial for powering the hydraulic functions of an excavator. In the case of the K3V63, the displacement is likely in the range of 60 to 70 ccrev.

DTP This could represent specific configuration or control options for the pump. For instance, D might indicate dual flow control, T could represent torque control, and P might represent pressure control. These options determine how the pump's flow rate and pressure are regulated to meet the demands of the hydraulic system.

Applications

The JCB 20925328 K3V63DTP hydraulic pump is specifically designed for use in JCB JS130 excavators. It is the main hydraulic pump responsible for converting the engine's mechanical power into high-pressure hydraulic fluid that powers the excavator's various functions, including

Arm and bucket movement

Track drive

Blade control (if equipped)

Attachment operation (breakers, augers, etc.)

Key Features

Reliability Kawasaki K3V pumps are known for their robust design and reliable operation, making them suitable for demanding applications like construction equipment.

Efficiency These pumps are designed to minimize energy losses and maximize hydraulic efficiency, which translates to better fuel economy and reduced operating costs.

High Power Density The compact design of K3V pumps allows for high power output in a relatively small package, making them suitable for space-constrained applications.

Maintenance

Regular maintenance of the JCB 20925328 K3V63DTP hydraulic pump is crucial for the excavator's performance, longevity, and overall reliability. Essential maintenance practices include

Oil changes and filter replacement Follow the recommended intervals in your JCB JS130 manual for hydraulic oil and filter changes. Clean oil is vital for proper pump lubrication and preventing wear.

Fluid level checks Regularly check the hydraulic fluid level according to the markings on the reservoir. Low fluid levels can lead to cavitation (formation and collapse of vapor bubbles) and damage the pump.

External inspection Look for leaks, loose connections, or visible damage on the pump housing and surrounding components. Address any issues promptly.

Replacement

If the hydraulic pump needs replacement, consider using a genuine Kawasaki K3V63DTP pump or a high-quality equivalent from a reputable manufacturer. Non-genuine replacements can compromise performance, reliability, and safety.

Consult a qualified technician for pump replacement, as it might involve specialized tools and procedures.
