Performance Curves

  1. Pump must be located with driving shaft coaxial to power take off. The drive system must not impose axial or radial load to pump shaft.
  2. Hydraulic fluid
    Use a mineral based hydraulic oil with additive to resist oxidatioon, Corrosion and foaming or an engine oil.
    Recommend viscosity
    Mineral oil 3÷5 E 50°C --- Enging oil SAE 10,20,30 depending on environment temperature.
    Operating Temperature range: 15 - 70°C
    Viscosity: 1.45 E
    Maximum viscosity during starting: 200 °E
  3. Filtration
    Before filling the system, ensure that circuit is perfectly clean. Filter must be adequate in capacity and preferably with blockage indicators. Filter must be changed according to operating instruction. Recommended filtering: Suction side 90 mesh, Return side 25 medium porosity.
  4. Piping Instruction
    Avoid sharp bends and restrictions on the circuit.
    Maximum inlet depression: 250mm/Hg
    Maximum oil speed suction side: 0.5÷1.5 Mt/sec
    Maximum oil speed outlet side: 3÷8 Mt/sec
    Maximum oil speed return side: 2÷3 Mt/sec
  1. No radial or axial forces may be permitted to act on the pump drive shaft.
  2. The alignment of motor and pump must be adjusted precisely.
  3. Always use a coupling which will permit compensation for any shaft displacement.
  4. When mounting the coupling, avoid applying axial force, i.e. never attempt to press or knock into place using a hammer or similar instrument.
