Manufacture and sale of hydraulic, pneumatic, and automobile parts and test devices

1. The pump is designed to be compact and lightweight.
2. The bearing load is small thanks to the hydraulically balanced design, allowing long life and operating economy.
3. The pump operates quietly even in hi gh-speed applications due to excellent cavitation characteristics.
4. The pump contains only a few component parts, made for easy maintenance.
5. Inlet and outlet ports can be located as desired at 90-deg. intervals without restriction on their relative positions.

Two pumps (HVP-FC1, HVP-FE1 series) are assembled as a unit and driven by one motor.
Pumps are usually arranged so that the pump with the larger capacity is located at the shaft side. The fluid pumped from the two pumps can be delivered to separate circuits to drive individual ac tuators or can be merged to drive a single actuator.

1. The pump provides a pressure and fluid flow appropriate for the load to save power and reduce fluid temperature rise, thus ensuring economical operation.
2. Since the pump is equipped with a pressure compensation mechanism, components such as a relief valve and unloading valve are not necessary.

Two variable-displacement pumps (HVP-V*1 series) are assembled as a unit and driven by one motor.

1. Low noise
   In operations at 14 MPa, the noise measured at a point 1 meter from the pump running at 1,200 min-1 is 53 dB (A) at cut-off and 58 dB (A) before cut-off.
2. High efficiency (energy saving)
   Volumetric efficiency: 95%, whole efficiency: 90% (at 13.5 MPa and 1,800 min-1)
3. High response

1. Low noise
   In operations at 14 MPa, the noise measured at a point 1 meter from the pump running at 1,200 min-1 is 56 dB (A) at cut-off and 60 dB (A) before cut-off.
2. High efficiency (energy saving)
   Volumetric efficiency: 95%, whole efficiency: 85 % (at 13.5 MPa and 1,800 min-1)
3. High response

The pump has a space-saving design, with two piston pumps driven by the same shaft.

1. The pump features minimal pulsation and low noise thanks to low-frequency sound.
2. The pump is compact and consists of few moving parts. It is lightweight since the pump body is made of special aluminum alloys.
3. Simple construction along with the use of plain metal ensure long life
4. High pressure and high efficiency

Two single pump units are assembled into one unit and driven by the common shaft. The fluid pumped from the two pumps can be delivered to separate circuits to drive individual actuators or can be merged to drive a single actuator.

The TC series pump, in which two single pumps are assembled serially in two stages in one housing, enables operation at a maximum discharge pressure of 30 MPa

1. The pump is compact and requires only a small installation area.
2. Coupling is not necessary since the pump is directly connected to the motor.
3. Center alignment work is not necessary after replacing a pump.

1. Low noise
2. Contains only a few component parts made for easy maintenance.
3. High-speed operation is possible while developing stable torque over the low to high speed range.
4. The operating direction is reversible.

1. Long life and high performance
2. Since the pump is a variable-displacement type, no relief valve is necessary.
3. Available in a series so that the discharge rate most appropriate to the application can be selected.
4. Can be mounted in the same manner as conventional hydraulic pumps.
