PERFORMANCE DATA
ROTARY DIRECTION.
Clockwise rotation viewed from shaft end is standard.
FLUIDS PERMISSIBLE.
When working pressure lower than 70 kg/cm², hydraulic oil with a viscosity ranging from 30~50 cSt. (ISO VG32) at 40°C is recommended.
When working pressure higher than 71 kg/cm², hydraulic oil with a viscosity ranging from 50-70 cSt(ISO VG68) at 40°C is recommended.
DRAIN PORT PIPING.
Drain connection must be piped directly to tank and below the oil level with a back pressure not exceed 0.3 kg/cm²
OIL TEMPERATURE RANGE.
Oil temperature range should be between 15°C~60°C for continuous operation and should be higher than 7°C at starting.
ALIGNMENT AND INSTALLATION OF PUMP.
The shaft alignment for pump and electric motor shall be limited to 0.05mm TIR. and 1 degree angular error.
INLET PORT PRESSURE.
Inlet port pressure should be -0.3kg/cm² to + 0.3 kg/cm².
FLOW ADJUSTMENT.
The flow will be reduced when the flow adjusting screw is turned clockwise and increased when anti-clockwise.
PRESSURE ADJUSTMENT.
The pressure will be increased when the pressure adjusting screw is turned clockwise and reduced when anti-clockwise.
P-Q CHARACTERISTICS (EX-WORK SET)
Flow setting: The max. flow as catalogue shown.
Pressure setting: The min. operating pressure range.
SLIDE SCREW.
The slide screw has been properly set at factory.(See P.74~75 schematic cross-section-28 for details.) Don't adjust it.
CAUTIONS FOR STARTING.
Start up the pump under No-Load codition and repeat to start and stop the motor several times to extract the air from inside of the pump and piping. Then keep a 10 minutes continuous running for a better de-airing.
PEAK-PRESSURE.
The peak pressure is 140 kg/cm² for code*2 & *3, and 210 kg/cm² for A4 & A5
