EC-0104 Smaller in Size and Lighter in MassAs indicated in the dimensional comparison presented below, the AR16 is smaller than the A16 (32 design). Also, the mass of AR16 is substantially lighter than the NoiseThe noise level of AR16 has been reduced by 1-2 dB (A) at full flow and full cut-off compared with that of the excellent A16 quiet pump.))

"AR" SERIES PISTON PUMPS AR16 / FluidsUse petroleum base 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 2 viscosity range is from 20 to 400 mm/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 of ContaminationDue 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.

3 Please maintain the degree of contamination within NAS Grade 10. The suction port must be equipped with at least a 100 m (150 mesh) reservoir type filter and the return line must have a line filter of under 10 installing the pump the filling port should be positioned of ShaftEmploy a flexible coupling whenever possible, and avoid any stress from bending or thrust. Maximum permissible misalignment is less than mm (.004 inches) TIR and maximum permissible misangular is less than . PressurePermissible suction pressure at inlet port of the pump is between -16 and +50 kPa (5 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 ( ft) from the oil level in the on PipingWhen using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates ex-cessive noise.

4 Whenever there is fear of excessive load, please use rubber PipingIn 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 drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than MPa ( PSI) and surge pressure of less than MPa ( PSI). Length of piping should be less than 1 m ( ft.), 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 (354 to 443 ). Do not apply bending and thrust torque to the AirIt may be necessary to bleed air from pump case and outlet line to remove causes of vibration.

5 An air bleed valve (Model No. ST1004- -10 , Catalogue No.: Pub.
