We would like to introduce the "ARL1 Series Piston Pump" that we handle. It operates at a pressure of 7 MPa and a rotational speed of 1500 r/min, with a noise level of 55 dB(A) at full cutoff measured at a distance of 1 meter, making it very quiet. Additionally, compared to the "AR Series Variable Piston Pump," it has a weight ratio and volume ratio that are both reduced by 40%, resulting in a very lightweight and compact design. 【Features】 ■ Low noise and high reliability backed by years of proven performance ■ Lightweight and compact design *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "AR Series Variable Piston Pump" that we handle. By adopting a compact housing design, the AR16 model is smaller than the A16 model (32 design), and the weight of the AR16 model is also reduced compared to the A16 model. Additionally, by employing a semi-cylindrical inclined plate bearing structure, we have achieved a reduction in vibration and noise while also making it more compact. 【Features】 ■ Compact ■ Low noise ■ High reliability *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "A Series Variable Piston Pump" that we handle. It has a high overall efficiency and sharp cutoff characteristics, allowing for energy savings. Additionally, due to its low loss power, it can keep the oil temperature rise low. Therefore, the capacity of the oil tank can be reduced. 【Features】 ■ High efficiency ■ Low noise ■ Energy savings ■ Ability to keep oil temperature rise low ■ Reduction in oil tank capacity *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "A3H Series High-Pressure Variable Piston Pump" that we handle. We offer four types of control methods: pressure compensator control type, constant horsepower (torque) control type, load sensing control type, and simplified dual pressure dual capacity type. The maximum operating pressure is 35 MPa. Additionally, we can supply pumps for special operating fluids (custom designs). Please contact us for more details. 【Lineup (partial)】 ■A3H16 ■A3H37 ■A3H56 ■A3H71 ■A3H100 *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "A3HG Series High-Pressure Variable Piston Pump." To ensure compatibility with pumps distributed globally, it complies with JIS standards as well as European standard ISO3019-2 and North American standard ISO3019-1. Additionally, while maintaining high performance, the rated pressure has been increased to 31.5 MPa, and the displacement volume is available in a wide range from 16 to 180 cm³/rev, making it suitable for a variety of applications as a medium to high-load capacity pump. 【Features】 ■ Complies with international standards ■ High pressure and wide displacement volume ■ Standard adoption of through-drive method ■ Rich variety of control methods *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "A3HM Series High-Pressure Variable Piston Pump" that we handle. We offer six types of displacement volumes ranging from 18.6 to 100.7 cm³/rev, making it suitable for a wide range of applications. Additionally, we provide three control methods. By simply rearranging the control valves installed, you can freely switch between different controls. 【Features】 ■ High pressure ■ Compact size ■ Wide range of displacement volumes ■ Abundant control methods ■ Standard adoption of through-drive method ■ Compliance with international standards *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "PM Series Pal Pump" that we handle. By integrating a low-noise, high-efficiency variable piston pump within the motor casing, we have achieved further miniaturization and noise reduction. Since we are using the A Series variable piston pump as is, maintenance is easy. 【Features】 ■ Low noise ■ Compact design ■ Easy maintenance *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "M Series Electric Motors" that we handle. These motors can be directly mounted to the "AR/A/A3H Series Variable Piston Pumps" and "PV2R Series Vane Pumps." We offer two types: the direct connection type M1 and M2, where the pump shaft is directly inserted into the hollow motor shaft, and the bell housing type M3 to M7, which uses a coupling. 【Features】 ■ Easy pump installation ■ No concerns about noise or vibration due to misalignment ■ Compact design reduces installation area ■ Safe as the rotating parts are not exposed *For more details, please refer to the PDF document or feel free to contact us.

We offer the "ASR Series AC Servo Motor Driven Pump," which allows for precise control of flow and pressure. The piston pump is directly driven by an AC servo motor, enabling control of the rotation speed from zero to the maximum speed, thus allowing for variable discharge volume. Additionally, the control deviation between the control signals (speed, pressure commands) from the upper level and the sensor signals is calculated by the AMSR controller, creating a feedback loop that drives the AC servo motor. 【Features】 ■ Control parameters can be digitally set using dedicated software ■ Energy-saving and low heat generation ■ Low noise ■ High performance ■ Space-saving and simplified wiring achieved with the digital setting AMSR controller *For more details, please refer to the PDF materials or feel free to contact us.
