The shaft end pump of multiple stage pump should have the largest displacement. It is also the maximum pressure of all pumps in multiple pump when the displacement is the same with all pumps. Likewise the secondary pump should have the second largest displacement of all pumps.

1. Hydraulic Oil:
   Use the hydraulic oil viscosity as same as ISO 46-68. (Viscosity over 90 cSt). The hydraulic oil cleanness should be kept within NAS 1638, 9 degree.
   Optimal Operation Viscosity: 20-100 cSt.
   Maximum Operation Viscosity: 1500 cSt.
   Minimum Operation Viscosity: 15 cSt.
2. Operating temperature: 5 to 70°C.
3. Suction Pressure: Absolute 0.8-1.3 kgf/cm2.
4. Filter: Suction Strainer 100um.
   Return Filter: 25 um.
   Hydraulic oil cleanness: NAS 1638 the 9th degree.
5. Flow speed: Suction Line: 2 M/sec.
   Pressure Line: 5 M/sec.
   Return Line: 3 M/sec.
6. Rotation:
   Do not cause any axial or radial pressure to the drive shaft. Use flexible coupling if necessary. Tighten closely the pump shaft and motor shaft. Do not use improper way of installing the pump, such as hitting. Be aware of the rotation direction of pump and motor. Any other means of installation, please consult with the suppliers.
7. Bleed the air when pump runs for the first time.
8. Please make sure the pump is on no-load state when starting and stop operation.
9. Do not fasten too tight when being connected with the suction line and pressure line.
10. Star-up operation: Follow the instruction and all other requirements before start up operation.
    a. Make sure the rotation of electric motor is right.
    b. Check the oil level of oil tank before starting and fill the oil when it is insufficient.
    c. Repeat power on and off when pump is first running until the pump start is to supply oil.
    d. Pump should be run under no load state when starting.
    e. Before starting, run the pump under no-load state, bleed the air out of the circuit to prevent noise and cavitation.
    f. Be aware of the temperature variation: Once the temperature of pump is apparently higher than oil, Stop pump running
       and check all equipment closely.
    g. When staring the running of pump at the first time or after repair, whole hydraulic system are liable to be contaminated.
    Pleaserun the pump under no-load state and replace or clean all filters after 100 hours.
    h. the operation of hydraulic system should be handled by professionals.
