Swash-plate Type Axial Piston Pumps for Open Circuits in Industrial Vehicles

1. K3V series pumps are very popular as reliable power source for construction
machines.
2. Various rotary group layouts are available to respond to applications.
3. Tandem type with PTO and Parallel type have joined the series
Some type of this series are: K3V63, K3V112 (S, DT, DP,DTP), K3V140, K3V180, K3V280

A Thorough Function Design Such Attractive Feature
1. High Power Density
A lighter and more compact machine with higher pressure rating and increased power
density (output power/mass) was obtained by adopting a half log type swash plate.
In particular, the double pump with its tandem arrangement, has eliminated a power
divider, has an increased transmission efficiency, and is lighter.
2. High Efficiency and Large Self-Priming Capability
The spherical valve plate and improved hydraulic balance provide stable cylinder rotati-
on, thus achieving high efficiency even in a low[pressure and low-speed operating range.
3. Long Life
A long life obtained by adopting main bearings of large capacity and the piston-return
mechanism that compensates for the wear of the shoe.
4. Low Noise
Even less noise has been achieved because of the optimum design of the valve plate and
the casing rigidity.
5. Wide Range of Controls
The pump can be controlled in various kinds of control methods and is capable of res-
ponding to either mechanical, hydraulic or electrical input.

The N series pump, which was used widely as a piston pump especially for construction machines, has been modified to the K3V series, meeting the present-day requirements. This pump has optimum functuon design and is provided with further improved power density, efficiency, and reliability, attained from our many years of experiences with the NV series.
K3V Series as Main / Hydraulic Pump application are widely use on :
- Samsung Excavator (MX222, SE210-1, SE210-2, SE280)
- Volvo Excavator (EC210B, EC290B)
- Daewoo Excavator (Solar S220, DH220, DH280-3, DH280-5, SL450, DH320)
- Hyundai Excavator (Robex R200, R200-2, R210-3, R210-7, R220-3, R250-3, R290, R450-7)
- Kobelco Excavator (K907-2,SK200-3, SK200-5, SK200-6, SK330)
- Halla Excavator (HE220LC, HE280)
- Sumitomo Excavator (SH200)
- Catterpillar Excavator (E350)
