ENTERING A NEW MARKET, AND REACHING A LARGER CLIENT BASE, IS A SMART
WAY TO MAXIMIZE THE POTENTIAL OF A PRODUCT

With more than 100 years of experience in
developing hydraulic components, Kawasaki has
a proven track record in product innovation. Utilizing
various advanced analysis techniques in product design
such as finite element method (FEM), computational
fluid dynamics (CFD) analysis, multi-body dynamics (MD)
analysis as well as simulation techniques, the company
has developed hydraulic equipment known for its
reliability and high performance.
Kawasaki has provided innovative and high-quality
products to meet the increasingly tough requirements of
excavator and construction machinery customers around
the world. With technological and manufacturing
expertise and experience accumulated in these fields,
the pump manufacturer has entered into a new field of
agricultural applications with the new K3VLC85 variable
displacement pump and the KLSS18 control valve
New applications
The K3VLC85 pump is a load sensing pump specifically
developed for agricultural tractors or agricultural
equipment. This 85cc pump has a rated pressure of
210bar and a maximum self-priming speed of 2,800rpm.
It is ideally suited for medium to large horsepower
tractors and boasts the characteristics of the firm’s
pumps, namely, high pump efficiency, low noise, low
pulsation, and highly stable and responsive control.
The K3VLC85 has a similar installation envelope to a
standard 60cc/rev unit making it a very compact pump
with high power density with regards to power-toweight
ratio. Its high suction capability requires no
boost pressure in suction line that hinders overall system
efficiency. This compact pump not only achieves high
pump efficiency with less fuel consumption but offers
flexibility for system configurations.

Just like other Kawasaki pumps, the K3VLC pump is
designed with its proven swash-plate type axial piston
pump design. This pump is designed to reduce
emissions of high frequency noise and pressure
pulsation. It provides a low noise solution and helps
to reduce operator fatigue and environmental burdens.
The K3VLC85 pump is equipped with a regulator that
provides highly stable and responsive control. Adopting
the basic regulator design of a widely recognized K3VL
pump, this pump achieves an optimum balance
between the metering characteristics and spring
stiffness that provides stable and responsive flow
control. This pump is available with load sensing
and/or pressure compensation control and can
optionally be fitted with a swash angle sensor.
To complement the K3VLC85 in
agricultural tractor applications the
firm has now developed a control
valve for on board and implement
control. The KLSS18 valve is the latest
additional to Kawasaki’s directional
control valves for agricultural
equipment.
The KLSS18 is electro-hydraulically actuated with
electric proportional control and integrated solenoid
drivers permitting a simple and easy interface with
|the machine controller. The KLSS18 valve is sectional
in construction and can be configured to meet the
needs of agricultural tractors by including features
such as hitch control.
The KLSS18 valve has a rated flow capacity of 180l/
min and pressure ratings to perfectly match tractor
applications. Kawasaki employs its pressure precompensated
design proven reliable in hydraulic valves
to deliver stable flow control regardless of pressure
fluctuations. This ensures stable performance.
The valve design provides highly accurate spool
control and improves accuracy in repetitive operations.
The KLSS18 valve can be optionally equipped with
pressure limiting and lock valves at either A port or B
port where required. Furthermore, this electronic
proportional valve is available with metric, UNF or BSP
threaded ports and is equipped with safety features that
allow for manual operation in case of machine failure.
These two new and complimentary products will be
launched at Agritechnica in November as Kawasaki
introduces its pump and valve technology to the
agricultural machinery market. iVT
