1 EIC--12- PISTON PUMPS Series Variable Features High efficiency Under the conditions of pressure 16 Kgf/cm² and speed 18 r/min. volumetric efficiency is over 98% and the overall efficiency is over 9%. Low noise level In the 16 pump, the noise level is as low as 57.3dB() [t the full cut-off pressure 21 Kgf/cm² with speed 15 r/min. at one meter horizontally away from pump head cover.] 16 Type performance characteristics 16 Type Noise level characteristics % N=18 r/min. Overall Efficiency db() 12 3 N=15 r/min Kgf/cm² ccomplishment of energy saving Because the overall efficiency is high and the cut-off characteristics is sharp, thus the input power may be saved. Noise Level Volumetric Efficiency 1 Efficiency 7 6 Full Cut-off Kgf/cm² Low heat generation Because of small power loss, it is possible to reduce the rise in oil temperature. ccordingly, capacity of a reservoir can be reduced 19
2 Instructions Hydraulic Fluids. Use petroleum base oil such as anti-wear type hydraulic oils or R & O ( Rust and oxidation inhibitor ) type hydraulic oils (ISO VG 32 or 46) with a viscosity range of 2 to cst at temperature of -6 C both to be satisfied. Control of contamination. Much care should be taken to maintain control over contamination of the operating oil which can otherwise lead to breakdown and shorten the life of the unit. Please maintain the degree of contamination within NS Grade 1. The suction port must be equipped with at least a 1 µm (15mesh) reservoir type filter and the return line must have a line type filter of under 1µm. Mounting When installing the pump the filling port should be positioned upwards. lignment of Shaft. Employ a flexible coupling whenever possible, and avoid any stress from bending thrust. Maximum permissible misalignment is less than.1 mm TIR and maximum permissible misangularity is less than.2. Suction. Permissible suction pressure at inlet port of the pump is between -.17 and +.5 Kgf/cm 2 (-125 mm Hg~+.5 Kgf/cm 2 ). For piping to the suction port, use pipes of the same diameter as that of the specified pipe flange to be used. Make sure that the height of the pump inlet port is within one meter from the oil level in the reservoir. Hints on Piping. When using steel piping for the suction of 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 of less than 1 Kgf/ cm 2 and surge pressure of less than 5 Kgf/cm 2. Recommended Drain Piping Size. Fix drain pipe for each side of the pump Model Number Series 1,16, ,7 9,145 Bleeding ir. It may be necessary to bleed air from pump case and outlet line to remove causes of vibration. n air bleed valve (Model No. ST ) is recommended for this purpose. Starting. Fitting Size 3/8 (Inside dia. 8.5 mm or more) Before starting, first time fill the pump case with clean operating oil through 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 directly to the tank or the actuator moves in a free load. [Volume of Pre-Fill Oil Required] Model Number Series 1/2 (Inside dia. 12 mm or more) 3/4 (Inside dia. 16 mm or more) Volume cm , , Inside Of Pipe ø 1 mm ø 12 mm ø 19 mm 2 Length of piping should be less than 1 m, and the pipe end should be submerged in oil.

Page 24 2 *1 Solenoid-two Control Type PL PH M SOL "OFF" PL 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. * O 3 *1 Compensator With Unloading Type M O SOL "OFF" 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 use in combination with the multistage pressure control valve. * 4 4E Proportional Electro Hydraulic Load Sensing Type Proportional Electro Hydraulic & Flow Control Type i1 M O. M O i2 (S Input Current i 1 L) (S Input Voltage L) (S Input Current i L) (S Input Voltage 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 regulated 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. 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 *1 Two- Two-Flow Control Type by System Pres. PH PL M O QH QL PL 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 * 22

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 the requirements. Page * * Series Variable 9 *1 Constant Power Control Type M O Pump input power can be controlled in accordance with the motor output. When the discharge pressure raises, the output flow decreases corresponding to the preset input power. The pump can act for function of 2 pumps, low pressure large-flow and high-pressure small-flow. Therefore, the motor capacity can be reduced. * * Control Type 1,"4" & "4E" are shown in catalogue.

Electric Source lways 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 5 Hz or 6 Hz, connect short plug in the amplifier to 6 Hz at the place where supplied frequency is 6 Hz. t this condition, maximum flow comes to the same value at 5 Hz. If short plug is used at 6 Hz without making the change, maximum flow increased in proportion to frequency. Painting on MP. BOX and Solenoid To Maintain suitable radiation effect, the amp. box and the solenoid of the control valve should not be painted.
