K5V200SH117R-5E29 Kawasaki Hydraulic Piston Pump | K5V200SH High Pressure Main Pump

Chengyuan Hydraulic presents the K5V200SH117R-5E29 axial piston pump, meticulously engineered as a premium-grade replacement for the Kawasaki K5V series. This model is a core component for the main hydraulic systems of 40-50 ton heavy-duty excavators (e.g., Volvo, Hyundai).

Functioning as the “heart” of the hydraulic circuit, Chengyuan ensures 100% Drop-in Interchangeability with original Kawasaki units in terms of mounting dimensions, splines, and control logic. Utilizing a high-strength swash-plate design and precision-machined piston groups, our pumps undergo 100% Simulation Load Testing at a rated 34.3MPa. This validation guarantees superior volumetric efficiency and response stability, providing the unyielding power required for the most demanding mining and excavation environments.

Key Technical Advantages:

• High Power Density Architecture: The reinforced swash-plate support reduces internal friction, enhancing volumetric efficiency under high pressure. This provides excavators with greater breakout force and faster cycle times.

• Advanced Heat Treatment: The cylinder block and valve plate utilize bi-metal sintering technology. Combined with high-frequency quenching and precision grinding, piston hardness exceeds HRC 60, significantly improving wear resistance and service life.

• Low Noise Flow-Path Optimization: By optimizing the suction port flow field and valve plate damping slots, fluid pulsations are suppressed. This reduces operating noise by 2-3 dB(A) compared to standard aftermarket products.

• Precise Tunability: The servo displacement mechanism offers millisecond-level response, ensuring perfect compatibility with mainstream controllers (e.g., Volvo EC460/EC480) for seamless power management.

Application Areas:

• Heavy Excavators: Specifically for Volvo EC460B, EC480, Hyundai R450/R480, and similar crawler models.

• Industrial Presses: Ideal for high-performance hydraulic punching and forging equipment.

• Drilling Rigs: Suitable for large rotary drilling rigs and mining excavation machinery.

Expert Maintenance Tips:

• Case Flushing & Venting: Before initial start-up, you MUST fill the pump case with clean hydraulic oil through the drain port and rotate the shaft by hand to bleed air. Dry starts will lead to immediate piston seizure.

• Suction Line Integrity: Never use fine filters in the suction line. Ensure suction vacuum does not exceed -0.01 MPa to prevent catastrophic cavitation.

• Fluid Contamination Control: Maintain system cleanliness at ISO 4406 18/16/13 or better. Regularly inspect filters and monitor oil moisture levels to prevent emulsification, which degrades precision components.
