K3VL PUMP

A high-efficiency, high-reliability, low-noise swash plate axial piston pump for industrial machinery.

Features Benefits
Low pulsation, low noise Significantly reduce pressure pulsation, the source of noise,
by applying our proprietary technology
High efficiency, high suction pressure, long life Optimal valve plate design improves efficiency, and durability is enhanced by using
high-load bearings and high-strength piston shoes.
Auxiliary gear pump connection and compound pump SAE standard auxiliary gear pump connection and tandem piston pumping possible
various control methods Unloading and pressure variable control are possible based on load sensing
and constant pressure type.

K3VG PUMP

산업기계용 고효율, 고신뢰성, 저소음의 사판식 액시얼 피스톤펌프입니다.

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
