Hydraulic Fluids Hydraulic Fluids Use petroleum based oils such as anti-wear type hydraulic oils equivalent to ISO VG-3 or 46. The recommended viscosity range is from 0 to 400 mm /s and temperature range is from 0 to, both of which have to be satisfied for the use of the above hydraulic oils. Control of Contamination 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 When installing the pump the filling port should be positioned upwards. 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 TIR and maximum permissible misangular is less than 0.. Suction Pressure Permissible suction pressure at inlet port of the pump is between -16.7 and +50 kpa. 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 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. 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. Drain Piping 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 and surge pressure of less than 0.5 MPa. Length of piping should be less than 1 m, and the pipe end should be submerged in oil. Model [Recommended Drain Piping Size] Fitting Size Inside Dia. of Pipe 3/8 A10, A16, A 10 mm or more [Inside Dia. 8.5 mm or more] A37, A45 A56, A70, A90, A100, A145 1/ [Inside Dia. 1 mm or more] 3/4 [Inside Dia. 16 mm or more] 1 mm or more 19 mm or more 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 65) is recommended for this purpose. 6

PISTON PUMPS Starting Before first staring, 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.

PISTON PUMPS Control Type Control Type Graphic Symbols Performance Characteristics Explanation Page "01" Pressure Compensator Type M O Output Flow Pressure 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. 31 A Series "0" Solenoid-two Pressure Control Type PL PH M O Output Flow SOL "OFF" PL Pressure SOL "ON" PH This type of control is ideal for an application where the output power of the actuator has to be controlled in two different load pressures while keeping the actuator speed nearly constant. 53 "03" Pressure Compensator with Unloading Type M O Output Flow SOL "OFF" Pressure SOL "ON" 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. The pump can be used in combination with the multistage pressure control valve. 61 "04" Proportional Electro- Hydraulic Load Sensing Type i 1 M O i (S Input Current i L) Output Flow Pressure (S Input Current i1 L) 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. 6 "04E" "04EH" Electro- Hydraulic Proportional Pressure & Flow Control Type Electro- Hydraulic Proportional Pressure & Flow Control Type (OBE Type) M O (S Input Voltage L) Output Flow Pressure (S Input Voltage L) 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. 7 8 "05" Two-Pressure Two-Flow Control Type by System Pres. PH PL M O Output Flow QH QL PL Pressure PH 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. 91 "06" Two-Pressure Two-Flow Control Type by Solenoid Valve PL PH M O Output Flow SOL"OFF" QH SOL"ON" QL PL PH Pressure This pump control is suitable for machining found on machine tool, where machining starts after the changeover from rapid advance, to feed has been made. 9 9

Control Type Control Type Graphic Symbols Performance Characteristics Explanation Page "07" Pilot Pressure Control Type Pressure Compensator M O Output Flow Pressure The pump is used in combination with the pilot relief valve or multistage pressure control valve. By controlling the pilot pressure, the full cut-off pressure can be remote-controlled according to your requirements. 93 Output Flow Pump input power can be controlled in accordance with the motor output. "09" Constant Power Control Type M O Output Flow Pressure Input Power When the discharge pressure rise, the output flow decreases corresponding to the preset input power. The pump can act for function of two pumps, lowpressure large-flow and high-pressure small-flow. Therefore, the motor capacity can be reduced. 101 This type of control enables one pump to act as two pumps (low-pressure and large-flow/high-pressure and small-flow-rate). Therefore, the motor capacity can be reduced. "00- Z500" Simple Two- Pressure Two-Flow Control Type When the system pressure increases near the preset PL pressure due to the load increase, the pump flow automatically decreases to QL. This type of control is suitable for an application like the press, where switching from rapid advance to feed is required just when the press (pressurizing) starts. The PH pressure can be remote-controlled with a separately located relief valve. With this type of control, it is easy to change the applied pressure setting when materials or shapes of the press are changed. 109 Availability of Control Type Mark " " in the table below refers to standard model.

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 Hz, connect short plug in the amplifier to Hz at the place where supplied frequency is Hz. At this condition, maximum flow comes to the same value at 50 Hz. If short plug is used at Hz without making the change, maximum flow increased in proportion to frequency. 74 Electro-Hydraulic Proportional Pressure & Flow Control Type

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 31 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 3. 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 Hz, connect short plug in the amplifier to Hz at the place where supplied frequency is Hz. At this condition, maximum flow comes to the same value at 50 Hz. If short plug is used at 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.
