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  0.2°.

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.

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.

In case AR16 and AR22 pump, a screw-in torque of fitting  is 40 to 50 Nm. Do not apply bending and thrust torque to  the fitting.

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   265) is

recommended for this purpose.

To protect your rights please read the following carefully

Bleeding air
It may be necessary to bleed air from pump case and outlet line to remove causes of vibration. An air bleed valve is recommended for this purpose.
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.
Setting Discharge Pressure and Delivery 
At 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.
Adjustment of Discharge Pressure 
Turning the adjustment screw clockwise, increases pressure.
