31N6-10051 31N6-10030 hydraulic pumps

The 31N6-10051 and 31N6-10030 are both part numbers for axial piston hydraulic pumps used in various applications, including excavators and other hydraulic machinery. These pumps are likely manufactured by Kawasaki Heavy Industries, a leading producer of hydraulic components.

31N6-10051

Application This pump is commonly used as the main hydraulic pump in Hyundai R210LC-7 and R220LC-7 excavators. It provides the power for various excavator functions like arm and bucket movement, track drive, blade control, and attachment operation.

31N6-10030

Application While the exact application is less clear, this pump might be used in other hydraulic machinery or could be an earlier model or variant of the 31N6-10051.

Key Characteristics

Axial Piston Pump These pumps convert the rotary motion of the shaft into reciprocating motion of pistons to generate hydraulic pressure. They offer high efficiency, reliability, and flow control capabilities.

Displacement The displacement of these pumps is likely 112 cubic centimeters per revolution (ccrev). This means they can deliver 112 cubic centimeters of hydraulic fluid per revolution of the shaft.

Verifying the Exact Pump Model

Here are ways to confirm the specific pump model for your application

Operator's Manual Refer to the operator's manual for your equipment. It should list the exact hydraulic pump model number and specifications.

Parts Diagram or Decal The pump itself might have a data plate or decal with the model number.

Contacting the Manufacturer or a Qualified Technician If unsure about the model number, contact the manufacturer of your equipment or a qualified technician specializing in hydraulic systems. They can identify the specific pump based on your equipment information (model, serial number, etc.).

Additional Information

Functions Powered by the Hydraulic Pump The hydraulic pump is the heart of the hydraulic system. It converts engine power into high-pressure hydraulic fluid that gets distributed throughout the system to power various functions like

Arm and bucket movement

Track drive

Blade control (if equipped)

Attachment operation (breakers, augers, etc.)

Maintenance Regular maintenance is crucial for optimal performance and longevity of the hydraulic pump. Refer to the operator's manual for specific intervals on oil changes, filter replacements, and fluid level checks.

Replacement When replacing the pump, consider a genuine Kawasaki 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 involves specialized tools and procedures.

Safety Precautions

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

Depressurize the system before any maintenance or repairs.

Wear appropriate PPE (gloves, safety glasses, sturdy footwear).

Consult qualified technicians for complex procedures.
