Operating Data

ROTARY DIRECTION

Clockwise rotation viewed from shaft end is standard.

FLUIDS PERMISSIBLE

When working pressure lower than 70 bar, hydraulic oil with a viscosity ranging from 30~50 cSt(ISO VG32). When working pressure higher than 71 bar .hydraulic oil with a viscosity ranging from 50-70 cSt(ISO VG68) at 40°C is recommended.(ISO VG32) 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 bar.

OIL TEMPERATURE RANGE

Oil temperature range should be between 15-60°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 -0.3 bar to +0.3 bar.

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 is non-adjustable and set at factory. Unauthorized persons cannot tamper with the desired setting.

CAUTIONS FOR STARTING

Start up the pump under No-Load condition 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 bar for code * 2 & * 3,and 210 bar for A4 & A5.
