Hydraulic Fluids Hydraulic Fluids
Control of Contamination
Use 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 Piping
When installing the pump the filling port should be positioned upwards.
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.
Alignment of Shaft Employ 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 Pressure
[Recommended Drain Piping Size] Fitting Size Model
Permissible 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 Piping When 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 Piping In 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.

Bleeding Air It 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.
When 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.

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. Linearity of input characteristics is excellent and easy to set. Hysteresis is lower,repeatability and reproducibility are fine.

Pump input power can be controlled in accordance with the motor output. When the discharge pressure rise, the output flow decreases corresponding to the preset input power. 105 The pump can act for function of two pumps, low-pressure large-flow and high-pressure small-flow. Therefore, the motor capacity can be reduced.

2. 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.

1. 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. 2. Discharge port for pump model "A16" and "A22" is available only the threaded connections. Detail of the pipe flange kits are shown on page 824.
Instructions Bleeding Air 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 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. Position of Cable Departure Position of cable departure can be changed. For details, refer to EDG-01 valve on page 672. Connection of Surge Cut-off Valve to "A" Series Pump (For A16 to A56 Type) If using surge cut-off valve (SF1105-A-10), connect between pilot port "PP" of this pump and port "PP" of surge cutoff 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. Surge Cut-off Valve (SF1105-A-10)

1. Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure. 2. When operating the pump exceeding the rated pressure, operating conditions are restricted. Refer to page 33 for the details. 3. 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. 4. 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.
Pipe Flange Kits For Pipe flange, refer to form of pressure compensator type on page 34.
Instructions Input Signal The pump is on unload condition when the pump is operated without input signal voltage. Electric Source Always turn off electric source whenever the connector for swash plate tilt angle sensor is removed. Compensation of Pump Maximum Regulated Flow at Frequency 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. Painting on Amp. Box and Solenoiod To maintain suitable radiation effect, the amp. Box and the solenoid of the control valve should not be painted.

1. Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure. 2. When operating the pump exceeding the rated pressure, operating conditions are restricted. Refer to page 33 for the details. 3. 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.
Pipe Flange Kits For Pipe flange, refer to form of pressure compensator type on page 34.
Instructions Input Signal The pump is on unload condition when the pump is operated without input signal voltage. Electric Source Always turn off electric source whenever the connector for swash plate tilt angle sensor is removed. Compensation of Pump Maximum Regulated Flow at Frequency 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. Painting on Amp. Box and Solenoiod To maintain suitable radiation effect, the amp. box and the solenoid of the control valve should not be painted.

1. 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. 2. Discharge port for pump model "A16" is available only the threaded connections. 3. 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.
