Renowned products including K3V and K3VL axial piston pumps, PV48 and RCV remote control valves, M5X swing motors, and Staffa high-torque motors are examples of Kawasaki’s success in the hydraulics industry.

Kawasaki hydraulic products and systems are utilized around the world to power a wide array of applications. Our products are routinely applied to the Mobile, Marine, and Industrial markets.

Hydraulic components and systems from Kawasaki Precision Machinery are used around the world in mobile machinery where high performance and reliability are critical. Mobile vehicles require power, efficiency and steady controlled load movements. Designed to operate under severe conditions, Kawasaki motors, pumps, valves and hydraulic control circuits are rigorously tested and documented before shipment. Mobile equipment operators everywhere depend upon the efficiency and reliability of Kawasaki Hydraulic Products.

Kawasaki's K3V, K5V and K7V axial piston pumps are widely used on excavators and other larger construction machines. Kawasaki pumps have earned an excellent global reputation through their exceptional performance, great quality and reliability. Our spherical valve plate and cylinder block provide excellent balancing capability, assuring maximum efficiency regardless of pressure or flow rate.

The M5X Series swash plate type piston motor is equipped with a "shockless" relief valve for precise control. These motors are ideal for swing applications where upper body control is required, such as in large excavators, cranes and forestry machines.

The variable displacement M3B Series axial piston hydraulic motor comes in a wide variety of sizes, providing flexibility to meet applications from small to very large crawler cranes and other construction machines. The motor’s spherical valve plate assures good cavitation resistance and high starting efficiency.

The K3VL Series pumps are based on the K3V design, where more than 2 million units have been supplied to the mobile industry. The K3VL Series pumps were specifically designed for the American and European markets, having SAE and ISO mounting, shaft porting, and through-drive configurations.

Widely used as a winch motor for construction machines such as truck cranes, the compact M3X Series hydraulic motor features a built-in mechanical brake to hold the load securely. Built-in relief and make-up valves allow easy installation directly on a gearbox.

PV48 Series joysticks and RCV Series foot control valves have become the industry standard in mobile applications. The PV48K features an aluminum body and dual area spool design, which results in light weight and reduced operating torque. The RCV Series is available with an internal damping option, which provides excellent stability.

Kawasaki M3X-RG Series low speed, high torque hydraulic motors are the right solution for applications requiring multiplied torque at lower speeds. A variety of motor sizes and gearboxes provide a wide range of geared high torque motors for heavy duty applications.

From small cartridge valves that control a single function, to powerful hydraulic motors and pumps with complex multi-valve controls, Kawasaki Hydraulic Components and complete systems are utilized in marine applications around the world. Kawasaki provides supplemental packages for your motor and pump needs. Whether your motor requires a stable brake system or your pump needs a controlled and uniform valve package, Kawasaki’s engineered solutions cover a wide variety of marine applications. Since equipment designers demand well-documented performance and reliability when they choose hydraulic components, Kawasaki offers a wide selection of rigorously tested components to fulfill customer needs. With over 93 years of experience in hydraulic technology, Kawasaki is the first choice of industry leaders.

Staffa HMB, HMC & HPC Series radial piston high-torque, low-speed motors meet the needs of applications that demand fine control or have special control requirements. The motor's modular design allows for a variety of valve attachments. It has multi-port surfaces which support several different control valves, such as counterbalance valves for braking pressure in winch drums.

For applications such as mooring winches, where reliability and high-torque are required, a Staffa HMC Series coupled with a ring gear offers a simple, economical solution. The motor’s hydrostatically balanced connecting rod and valve spool design minimizes internal metal to metal contact, reducing friction for high mechanical efficiency and long motor life. Staffa motors have demonstrated their reliability in over 55 years of successful operation worldwide.

Kawasaki high pressure, long life K3VL & K3VG Series hydraulic pumps provide high pressure (4600 & 5000 psi) and continuous driving capability required for applications such as derrick cranes and winches.

The M3X Series fixed displacement swash plate type axial piston motor has high starting efficiency due to its spherical valve plate design. Shaft creep is minimized because of stable retention of the cylinder, enabling the motor to hold a windlass drum steady, with minimal slip. M3B variable displacement axial piston motors are also widely used in marine winch applications to satisfy various torque and speed requirements.

With 93 years of hydraulic experience, Kawasaki remains an industry leader with some of the most technically advanced designs on the market today. Kawasaki’s Hydraulic components are known around the world for providing the high reliability and controllability valued in today’s complex industrial environment. Highly advanced hydraulic control systems contribute to productivity improvements by achieving high- speed, precise control of industrial machinery. Superior technology, global acceptance, and proven reliability make Kawasaki Hydraulic Components a leading choice of machine builders for today’s innovative applications.

The K3VL Series pump is designed for medium to heavy-duty applications where high pressure and low output pulsation are critical. Various control options are available including load-sensing, electronic flow control, torque limiting and integral unloading control.

HMB, HMC & HPC Series Staffa radial piston high-torque low-speed motors offer consistent, controlled acceleration of loads and smooth, steady operation. Direct drives are a preferred solution to combination drives in injection molding machines and other industrial high torque applications. Engineered for long life under demanding loads, Staffa motors provide exceptional starting torque and mechanical efficiency.

In applications that demand rapid, precise control, the K3VG Series hydraulic pump has built-in electronic controls for outstanding controllability.

Industries that operate around the clock depend upon Kawasaki K3VG Series high efficiency axial piston pumps, which use the same internal components as K3V Series pumps, to ensure ultra-high reliability. In a steel rolling mill, K3VG pumps supply a continuous flow and steady pressure to cylinders that control the movement of the rollers.

Multiple M3X Series axial piston hydraulic motors provide the driving force to turn a giant boring machine efficiently. A special spherical surface type valve plate significantly improves the starting efficiency, enabling the motor to start the machine under full load.

ERU Series - Electronic Type Joystick Pilot Valves (for Mobile Usage)The ERU Series has the same look, feel, and proven performance as our hydraulic pilot valves. All of the ERU units feature a reliable and long life non-contact type potentiometer. The body of the ERU is constructed with a heavy duty water proof and electromagnetic noise resistant housing. The ERU controllers can be specified with voltage or current outputs. The ERUH modulation handle features a non-contact type sliding thumb switch, which can control a proportional solenoid directly.
