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°.
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.
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.
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.
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.
