use the pipes of the same diametre as that of the specified pipe flange to be used.
High efficiency Under the conditions of pressure 16 MPa (2320 PSI)
or R & O (Rust and Oxidation inhibitor) type hydraulic oils e quivalent to ISO VG-32
 Whenever there is fear of excessive load, please use rubber hoses. 7.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 p ump position to prevent air in the suction line.
which have to be satisfied for the use of the above hydraulic oils.
 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.
3.Mounting When installing the pump the filling port should be positioned upwards. 
4.Alignment of Shaft Employ a flexible coupling whenever possible,
and avoid any s tress from bending or thrust.  Maximum permissible misalignment is less than 0.1 mm
 (. 004 inches) TIR and maximum permissible misangular is less than 0.2°.
 and shorten the life of the unit.  Please maintain the degree of contamination within NAS Grade
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 (14.5 PSI)
and surge p ressure of less than 0.5 MPa (72.5 PSI).  Length of piping should be less
and s peed 1800 r/min, the volumetric efficiency is over 98% and the overall efficiency is over 90%.
Low noise level In the "A16" pump, the noise level is as low as 57.3 dB(A)
[ at the full cut-off pressure 21 MPa (3050 PSI) with speed 1500 r/min one metre
(3.3 ft.) horizontally away from pump h ead cover.]
1.Hydraulic Fluids Use petroleum based oils such as anti-wear type hydraulic oils
Make s ure that the height of the pump suction port is within one m etre (3.3 ft)
 5.Suction Pressure Permissible suction pressure at inlet  port of the pump is between -16.7
 and +50 kPa (5 in.Hg Vacuum and 7 PSIG).  For piping to the suction port,
than 1 m (3.3 ft.), and the pipe end should be submerged in oil.
or 46. The recommended viscosity 2  r ange is from 20 to 400 mm /s (98 to 1800 SSU)
and temperature range is from 0 to 60° (32 to 140°F), both of
 from the oil level in the reservoir. 6.Hints on Piping When using steel pipes for the suction
or discharge ports, excessive load from the piping to the pump generates excessive noise.
2.Control of Contamination Due caution must be paid to maintaining control
 over contamination of the operating oil which can otherwise lead to b reakdowns
