K3VG PUMP
It is a swash plate type axial piston pump with high efficiency, high reliability, and low noise for industrial machinery.
| Features | Benefits |
|---|---|
| High pressure/long life | Long life by applying high load capacity bearing and shoe wear compensation function |
| low noise | A swash plate support structure that suppresses vibration is added. A unique casing structure with small size and high rigidity realizes low noise. |
| Excellent efficiency and self-priming performance | A stable rotational shape of the cylinder can be obtained by improving the hydraulic balance by using a spherical valve plate. |
| various control methods | Equipped with various control methods using hydraulic pressure and electricity (flow control, pressure control, horsepower control) |
| auxiliary gear pump | Gear pumps of various sizes can be installed as an option |
