 Hydraulic oil
 A viscosity grade of ISO VG32 or ISO VG46 is
recommended.
 Avoid using MIL-spec. High Water Base Fluid (HWBF), R&D
type hydraulic fluid, or spindle oil.
 Maintain the fluid temperature inside the tank in the range 10
to 45°C when using a water-glycol hydraulic fluid or water/oil
emulsion type hydraulic fluid.
 Recommended contamination level of hydraulic fluid
Operating pressure MPa Up to 13.7 13.7 to 20.6 Over 20.6
Recommended
contamination level
ISO class 20/18/15 19/17/14 18/16/13
NAS class 10 9 8
Use clean hydraulic fluid that satisfies the recommended
contamination level for the operating pressure.
 Installation and alignment
 Ensure that the eccentricity of the drive shaft and pump shaft
is no greater than 0.05 mm (TIR), and run the pump with no
force acting perpendicularly on the pump shaft.
Misalignment between the shaft centers will cause damage to
bearings and oil seals, generate noise and vibration, and lead
to pump accidents.
 Avoid crosswise drive using a belt, chain or gears (it will
cause noise generation or damage to the bearings).
 The pump shaft can be installed vertically.
 Restrict the clearance between the spigot joint of the flange
and the hole to +0.01 to +0.05 mm in diameter.
 Restrict the clearance between the key shaft and the coupling
hole to +0.003 to +0.025 mm in diameter.
 Filters
 Use a suction filter with 150 meshes per inch at the inlet side.
 In the return line to the tank at the discharge side, use a line
filter with a filtration accuracy of 25 µm or better.
 For delivery pressures of 14 MPa {140 kgf/cm2
} or greater,
use a line filter with a filtration accuracy of 10 µm or better.
 Piping
 Ensure the suction port is airtight. Aeration will cause
abnormal noise.
 When using steel pipes for piping, take care not to force the
pump off center.
Forcing the pump off center with pipes may cause abnormal
noise.
 At start
 Fill inside the pump and the hydraulic system with the
hydraulic fluid before starting operation.
 After checking that all hydraulic circuits and electrical
circuits are ready for operation, set the hydraulic circuit at the
load side in the no-load status before starting the pump.
 When the pump is driven for the first time, turn the power
switch to the motor on and off a few times to let the air out of
the piping and then run it continuously at full speed.
 At a fluid temperature of 7°C or lower, warm up the pump by
running it at a pressure of 2 MPa maximum and increase the
pressure when the fluid temperature has risen.
(Note that the pressure must be 0.7 MPa minimum.)
 If there is a temperature difference of 20°C or greater
between the pump and fluid, warm up the pump to reduce the
temperature difference to within 20°C before running it.
 Suction pressure
 Keep the suction pressure within the permissible suction
pressure of the pump.
 High suction pressures will generate cavitation and cause
damage to the parts, noise, and vibration, resulting in a
shorter pump service life.
 The discharge pressure must always be larger than the suction
pressure.
