K3VL200/B-1BRKM-P0 Kawasaki Axial Piston Pump 200cc 320bar

Product Overview

The K3VL200/B-1BRKM-P0 is a Kawasaki K3VL Series size 200 swashplate-type axial piston variable pump with a nominal displacement of 200 cm³/rev, rated working pressure of 32 MPa (320 bar), and peak pressure of 35 MPa (350 bar). Designed for open-circuit operation, it is suitable for mobile and industrial hydraulic applications and is the largest standard displacement in the K3VL series.

The K3VL series was developed based on Kawasaki’s proven K3V series pumps, which have extensive field experience in construction machinery applications. The series is designed for load-sensing and constant-pressure hydraulic circuits. Through a unique mechanism resulting from Kawasaki’s long-term research, pressure pulsation — the primary source of hydraulic noise — is drastically reduced, achieving industry-leading noise levels. The series offers a wide range of control options including load sensing, pressure constant, power control, torque limiting, and electric displacement control, configurable to match specific machine requirements.

Manufactured to exact Kawasaki OEM specifications, the mounting flange, drive shaft spline, and port layout are fully consistent with the original pump for true drop-in interchangeability — no piping or coupling modification required. Every unit undergoes 100% simulated operating condition testing before shipment.

Key Technical Advantages

1. Ultra-Low Pressure Pulsation Design: The K3VL200/B-1BRKM-P0’s core technical feature is its unique low-pulsation mechanism. Kawasaki’s proprietary swashplate and valve plate design, developed through long-term research, drastically reduces hydraulic pressure pulsation — the primary source of system noise and vibration. This design ensures smooth output flow and minimal system pressure fluctuation during operation at 32 MPa, effectively extending hydraulic piping and seal service life while significantly reducing machine noise levels.

2. Wide Control Options with Precise Constant Pressure Control: The K3VL series is based on load-sensing and constant-pressure control types, with additional options including unloading control, power control, torque limiting control, and electric displacement control. This model features a pressure regulator (DR constant pressure control) that automatically reduces the swashplate angle to maintain constant system pressure when the set value is reached, eliminating unnecessary power consumption and fluid heating. The constant pressure control offers short response time and excellent pressure stability, suitable for industrial hydraulic systems requiring prolonged pressure holding.

3. High Reliability and Long Service Life: The K3VL series incorporates Kawasaki’s mature technology and rigorous manufacturing processes accumulated in the construction machinery pump field. Critical running surfaces are made from wear-resistant alloy steel with precision machining and hardening. The robust pump body withstands shock and vibration loads encountered in mobile machinery operations. Under normal maintenance conditions, the series delivers outstanding reliability and long service life, representing a mature platform proven over long-term market application.

4. Excellent Self-Priming Performance and Wide Speed Range: The pump achieves adequate suction performance at its self-priming speed of 1,900 rpm without the need for a charge pump. With boosted inlet conditions (boosted speed 2,200 rpm), the operating speed range can be further extended to meet different drive configurations. The minimum speed of 600 rpm ensures stable output under low-speed conditions.

5. Flexible Drive Interface and System Compatibility: The K3VL200/B features an SAE E 4-bolt mounting flange and SAE keyed shaft (44.45 mm diameter), with both pressure and suction ports using SAE J518C standard flange connections. This interface configuration is fully consistent with the original Kawasaki pump, allowing direct replacement without piping or coupling modification — dramatically reducing equipment repair downtime.

Application Areas

• Material Handling: Telehandlers, reach stackers — hydraulic power sources

• Marine Hydraulics: Ship deck machinery, steering gear hydraulic systems

• Industrial Hydraulics: Hydraulic presses, injection molding machines, test stands — constant pressure systems

• Agricultural Machinery: High-horsepower tractors, combine harvesters

• Mining Machinery: Underground drilling rigs, mining haul vehicle hydraulic drives

Expert Maintenance Tips

1. Shaft Alignment and Flange Connection: Concentricity deviation between the pump and drive shaft must be less than 0.05 mm, with angular deviation less than 0.25°. The K3VL200/B uses an SAE E 4-bolt flange. Tighten flange bolts in diagonal sequence for even loading. Check that the original mounting base locating step is in good condition — repair the base before installing a new pump if worn.

2. Initial Start-Up Filling and Bleeding: Pre-fill the pump with clean HL/HLP mineral oil through the case drain port before installation. Case fill capacity is approximately 3.0 L. Start at the minimum speed of 600 rpm and observe a steady oil flow from the case drain port free of bubbles. The constant-pressure controlled pump produces near-maximum displacement until system pressure reaches the set value, and a steady leakage flow from the case drain port is normal. Once bleeding is complete, gradually increase to working pressure.

3. Constant Pressure Controller Setting Verification: This model is equipped with a pressure regulator (DR), factory-calibrated to standard specifications. After pump replacement, verify the setting matches the original system using a calibrated pressure gauge. If adjustment is required, use dedicated tools and record the original setting for restoration. The pressure setting must not exceed the rated pressure of system components.

4. Rotation Direction Verification: This model is clockwise (right-hand) rotation. Driving it counter-clockwise is strictly prohibited — incorrect drive direction will reverse the suction and pressure sides, causing severe rotating group damage within a short period.

5. Fluid Cleanliness and Viscosity Management: Use HL/HLP mineral oil with a viscosity range of 10–1,000 cSt (standard operating range 10–200 cSt) and fluid temperature of -20 °C to +95 °C. System filtration should meet ISO 4406 18/15. Replace filter elements after the first 500 operating hours, then every 1,000 hours or annually thereafter.

6. Case Drain Line Configuration: The case drain line must return directly to the reservoir with backpressure not exceeding 1 bar (continuous) / 4 bar (peak). The drain line inner diameter must be sufficient to ensure unobstructed drainage during cold-start high-viscosity conditions.
