Hydraulic Fluids
Hydraulic Fluids Control of ContaminationUse petroleum base oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG-32 or 46. The recommended viscosity range is from 20 to 400 mm2/s (98 to 1800 SSU) and temperature range is from 0 to 60 °C (32 to 140 °F), both of which have to be satisfied for the use of the above hydraulic oils.
Due caution must be paid to maintaining control over contamination of the operating oil which can otherwise lead to breakdowns and shorten the life of the unit.Please maintain the degree of contamination within NAS Grade 10.The suction port must be equipped with at least a 100 µm (150 mesh) reservoir type filter and the return line must have a line type filter of under 10 µm.
Instructions
Mounting Drain PipingWhen installing the pump the filling port should be positioned upwards.
Alignment of ShaftEmploy a flexible coupling whenever possible, and avoid any stress from bending or thrust.Maximum permissible misalignment is less than 0.1 mm (.004 inches) TIR and maximum permissible misangular is less than 0.2°.
Suction PressurePermissible suction pressure at inlet port of the pump is between -16.7 and +50 kPa (5 in.Hg Vacuum and 7 PSIG).For piping to the suction port, use the pipes of the same diametre as that of the specified pipe flange to be used.Make sure that the height of the pump suction port is within one metre (3.3 ft) from the oil level in the reservoir.
Hints on PipingWhen using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates excessive noise.Whenever there is fear of excessive load, please use rubber hoses.
Suction PipingIn case the pump is installed above the oil level, the suction piping and suction line filter should be located lower than the pump position to prevent air in the suction line.
Install drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than 0.1 MPa (14.5 PSI) and surge pressure of less than 0.5 MPa (72.5 PSI).Length of piping should be less than 1 m (3.3 ft.), and the pipe end should be submerged in oil.In case AR16 and AR22 pump, a screw-in torque of fitting is 40 to 50 Nm (354 to 443 IN.1bs.). Do not apply bending and thrust torque to the fitting.
Bleeding AirIt may be necessary to bleed air from pump case and outlet line to remove causes of vibration. An air bleed valve (Model Number ST1004-*-10*, Page 820) is recommended for this purpose.

StartingBefore first starting, fill pump case with clean operating oil via the filling port.In order to avoid air blockage when first starting, adjust the control valves so that the discharged oil from the pump is returned direct to the reservoir or the actuator moves in a free load.
Setting Discharge Pressure and DeliveryAt the time of shipment, the unit has been preset to maximum delivery and minimum discharge pressure.Adjust the preset delivery and pressure to meet your system requirements.
Turning the adjustment screw clockwise, increases pressure.
Turning the delivery adjustment screw clockwise, decreases delivery.

Hydraulic Fluids
Hydraulic Fluids Control of ContaminationUse petroleum based oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG-32 or 46. The recommended viscosity range is from 20 to 400 mm2/s (98 to 1800 SSU) and temperature range is from 0 to 60°C (32 to 140°F), both of which have to be satisfied for the use of the above hydraulic oils.
Due caution must be paid to maintaining control over contamination of the operating oil which can otherwise lead to breakdowns and shorten the life of the unit.Please maintain the degree of contamination within NAS Grade 10.The suction port must be equipped with at least a 100 µm (150 mesh) reservoir type filter and the return line must have a line type filter of under 10 µm.
Instructions
Mounting Drain PipingWhen installing the pump the filling port should be positioned upwards.
Alignment of ShaftEmploy a flexible coupling whenever possible, and avoid any stress from bending or thrust.Maximum permissible misalignment is less than 0.1 mm (.004 inches) TIR and maximum permissible misangular is less than 0.2°.
Suction PressurePermissible suction pressure at inlet port of the pump is between -16.7 and +50 kPa (5 in.Hg Vacuum and 7 PSIG).For piping to the suction port, use the pipes of the same diametre as that of the specified pipe flange to be used. Make sure that the height of the pump suction port is within one metre (3.3 ft) from the oil level in the reservoir.
Hints on PipingWhen using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates excessive noise.Whenever there is fear of excessive load, please use rubber hoses.
Suction PipingIn case the pump is installed above the oil level, the suction piping and suction line filter should be located lower than the pump position to prevent air in the suction line.
Install drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than 0.1 MPa (14.5 PSI) and surge pressure of less than 0.5 MPa (72.5 PSI).Length of piping should be less than 1 m (3.3 ft.), and the pipe end should be submerged in oil.
Bleeding AirIt may be necessary to bleed air from pump case and outlet line to remove causes of vibration. An air bleed valve (Model Number ST1004-*-10*, Page 820) is recommended for this purpose.

"A16" type performance characteristics
"A16" type noise level characteristics
Under the conditions of pressure 16 MPa (2320 PSI) and speed 1800 r/min, the volumetric efficiency is over 98% and the overall efficiency is over 90%.
In the "A16" pump, the noise level is as low as 57.3 dB(A) [at the full cut-off pressure 21 MPa (3050 PSI) with speed 1500 r/min one metre (3.3 ft.) horizontally away from pump head cover.]
Because the overall efficiency is high and the cut-off characteristics is sharp, thus the input power may be saved.
Because of small power loss, it is possible to reduce the rise in oil temperature. Accordingly, capacity of a reservoir can be reduced.

(OBE Type)
When the system pressure increases and comes close to the preset cut-off pressure, the pump flow decreasesautomatically while maintaining the set pressure as it is.
This type of control is ideal for an application where theoutput power of the actuator has to be controlled in twodifferent load pressures while keeping the actuator speed nearly constant.
It is suitable for a situation where a long unloading time is required and heat generation and noise have to be kept at their lowest levels.
This pump control is suitable for machining found onmachine tool, where machining starts after the changeover from rapid advance, to feed has been made.
The pump can be used in combination with the multistage pressure control valve.
Linearity of input characteristics is excellent and easy to set.Hysteresis is lower, repeatability and reproducibilityare fine.

This is an energy-saving type control which regulates the pump flow and load pressure to be at absolute minimum necessary level to operate the actuator. Pump flow rate and cut-off pressure are controlled proportional to the input current to the control device on the pump and the input current is regurated by the specific amplifier.
This type of control has the pressure sensor and tilt angle sensor in the pump. The pump is used with the external amplifier (amplifier is integrated into pump in case of "04EH").Flow and pressure can be controlled in proportion to input voltage by only one control valve.The features has been greatly improved by electrical feedback of swash plate tilt angle correspond to flow rate and load pressure to control valve.
This type of control is suitable for an application like "Presses" where the changeover from rapid advance to feed is required just when the pressing (pressurizing) starts.

Applicable only for "A70/90/145"
The table above shows specifications for using petroleum based oils.Pumps (customized design) for special fluids are also available. Their operating pressure and maximum shaft speed however differ from the values in the table above depending on the fluid type.Range of operating temperature and viscosities may differ from those of petroleum based oils due to their characteristics.
The figures in brackets are for A22 type.
As the specific gravities of water-glycol fluids and phosphate ester type fluids are higher than one, an overhead reservoir is required when pumps are operated at 1500 r/min or more.
For the design numbers of pumps for European Design and North American Design Standards, please contact us.
Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure.
Care should be taken in cases of used at a higher pressure than the rated pressure, because operating terms may be restricted. For example, if used as per maximum illustrated operating conditions, intermittent time at maximum flow is restricted to under 1/5 of one cycle time and under six seconds simultaneously. Conditions may vary according to the actual working pressure and delivery (inclination angle of the swash plate). Consult factory or Yuken sales representative for further information.

In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of the flanges. Therefore, please pay cautious attension to the operating pressure when the socket welding flanges are used.
In order to get steadily controlled pressure and flow, bleed air by loosening the air vent screw and fill solenoid armature with operating oil.
Manual adjustment screws may be used for initial running adjustment or in case of electrical failures in order to adjust pressure and flow temporarily. In case of normal use, put the manual adjustment screws back in their preset positions.
If using surge cut-off valve (SF1105-A-10), connect between pilot port "PP" of this pump and port "PP" of surge cut-off valve as pilot piping (refer to drawing below).Inside diameter of pipe should be more than 8 mm(.32 in.).Consult Yuken of detail of surge cut-off valve.

Whenever setting pressure, make sure the full cut-off pressure neverexceeds the maximum intermittent pressure.
When operating the pump exceeding the rated pressure, operating conditions are restricted. Refer to page 33 for the details.
For detail specifications of power amplifiers, refer to page 780.
The figure mentioned in the above table are those obtained using Yuken's amplifier.
Step response depends on circuit and operating conditions. Data shown in the table above is an example based on the condition right.

Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure.
When operating the pump exceeding the rated pressure, operating conditions are restricted. Refer to page 33 for the details.
Maximum flow differs to shaft speed. The value listed above indicates shaft speed of 1800 r/min. For other shaft speed calculate by the ratio of shaft speed.
Specifications
Pipe Flange Kits
For Pipe flange, refer to form of pressure compensator type on page 34.
InstructionsInput SignalThe pump is on unload condition when the pump is operated without input signal voltage.
Electric SourceAlways turn off electric source whenever the connector for swash plate tilt angle sensor is removed.
Compensation of Pump Maximum Regulated Flow at Frequency
Painting on Amp. Box and SolenoiodTo maintain suitable radiation effect, the amp. Box and the solenoid of the control valve should not be painted.
To secure the required minimum pressure, special sequence valves are available, to be directly installed at the discharge port of the pump. Consult Yuken for details.
If the same maximum flow is required at 50 Hz or 60 Hz, connect short plug in the amplifier to 60 Hz at the place where supplied frequency is 60 Hz. At this condition, maximum flow comes to the same value at 50 Hz.If short plug is used at 60 Hz without making the change, maximum flow increased in proportion to frequency.

Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure.
When operating the pump exceeding the rated pressure, operating conditions are restricted. Refer to page 33 for the details.
Maximum flow differs to shaft speed. The value listed above indicates shaft speed of 1800 r/min. For other shaft speed calculate by the ratio of shaft speed.
Specifications
Pipe Flange KitsFor Pipe flange, refer to form of pressure compensator type on page 34.
InstructionsInput SignalThe pump is on unload condition when the pump is operated without input signal voltage.
Electric SourceAlways turn off electric source whenever the connector for swash plate tilt angle sensor is removed.
Compensation of Pump Maximum Regulated Flow at Frequency
Painting on Amp. Box and SolenoiodTo maintain suitable radiation effect, the amp. box and the solenoid of the control valve should not be painted.
If the same maximum flow is required at 50 Hz or 60 Hz, connect short plug in the amplifier to 60 Hz at the place where supplied frequency is 60 Hz. At this condition, maximum flow comes to the same value at 50 Hz.If short plug is used at 60 Hz without making the change, maximum flow increased in proportion to frequency.

In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of hat flanges. Therefore, please pay cautious attention to the operating pressure when the socket welding flanges are used.
As dimensions of the pipe flange mounting surface are conformed to SAE 4 Bolt Split Flange (Standard Pressure Series), pipe flanges conforming to the SAE Standards can be used.
Detail of the pipe flange kits are shown on page 824.

Hydraulic Fluids
Hydraulic Fluids Control of ContaminationUse petroleum base oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG-32 or 46.The recommended viscosity range is from 20 to 400 mm2/s (98 to 1800 SSU) and temperature range is from 0 to 60°C (32 to 140°F), both of which have to be satisfied for the use of the above hydraulic oils.
Due caution must be paid to maintaining control over contamination of the operating oil which can otherwise lead to breakdowns and shorten the life of the unit. Please main-tain the degree of contamination within NAS Grade 10.The suction port must be equipped with at least a 100 µm (150 mesh) reservoir type filter and the return line must have a line filter of under 10 µm.
Instructions
Mounting Drain PipingWhen installing the pump the filling port should be positioned upwards.
Alignment of ShaftEmploy a flexible coupling whenever possible, and avoid any stress from bending or thrust.Maximum permissible misalignment is less than 0.1 mm (.0039 inches) TIR and maximum permissible misangular is less than 0.2°.
Suction PressurePermissible suction pressure at suction port of the pump is between -16.7 and +50 kPa (5 in.Hg Vacuum and 7 PSIG). In case of the speed is over 1800 r/min, adjust the pressure 0 to +50 kPa (0 to 7 PSIG).For piping to the suction port, use the pipes of the same diametre as that of the specified pipe flange to be used.Make sure that the height of the pump suction port is whithin one metre (3.3ft.) from the oil level in the reservoir.
Hints on PipingWhen using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates excessive noise.Whenever there is fear of excessive load, please use rubber hoses.
Suction PipingIn case the pump is installed above the oil level, the suction piping and suction line filter should be located lower than the pump position to prevent air in the suction line.
Install drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than 0.1 MPa (15 PSI) and surge pressure of less than 0.5 MPa (70 PSI).Length of piping should be less than 1 m (3.3 ft.), and the pipe end should be submerged in oil.
[Recommended Drain Piping Size]
Model Volume cm3(in.3)
[Volume of Pre-fill Oil Required]
Safety ValveWhen delivery line is blocked suddenly, surge pressure is occurred so a safety valve should be set in the circuit to eliminate any damage on equipment and piping.
Bleeding AirIt may be necessary to bleed air from pump case and outlet line to remove causes of vibration.
StartingBefore first staring, fill pump case with clean operating oil via the fill port.In order to avoid air blockage when first starting, adjust the control valves so that the discharged oil from the pump is returned direct to the tank or the actuator moves in a free load.

"14"Load Sensing Type
When the system pressure increases and comes close to the preset cut-off pressure, the pump flow decreases automatically while maintaining the set pressure as it is.
This is an energy-saving type control which maintains the pump flow and load pressure at the absolute minimum necessary level to operate the actuator.
This type of control automatically regulates the output flow so that the inlet-outlet differential pressure of the flow control valve at the output side is constant. To do so, the load pressure must be introduced to the load sensing port "L" of the pump through the external piping.
This type of control provides the remote control of the full cut-off pressure by connecting a remote control relief valve to the pilot port "PP".
A flow control valve is not included with the pump. Install the valve separately.
M
O
This type of control can control the pump input power according to the motor output.
When the system pressure increases, the pump swash plate tilt angle (output flow) decreases, in correspondence to predetermined shaft input values.
This type of control can enable one pump to act as two pumps (low-pressure and large-flow/high-pressure and small-flow). Therefore, the motor capacity can be reduced.
