Pump Installation
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. For gear or belt drive please contact our Engineering Departement.
Hydraulic fluid
Use mineral based hydraulic oil with additive to resist oxidation, corrosion and foaming, or an engine oil.
Recommended viscosity:
Mineral oil 3÷5 °E 50 °C - Engine oil SAE 10, 20, 30 depending on environment temperature.
Operating temperature range: -15 +80 °C
Minimum viscosity: 1.45 °E
Maximum viscosity during starting: 200°E
Filtration
Ensure before filling the system that circuit is perfectly clean. Filters must be adequate in capacity, and preferably with blockage indicators.
Filters must be changed according to operation instructions.
Recommended filtering: Suction side - 90 mesh - Return side - 25 medium porosity.
Piping instructions
Avoid sharp bends and restrictions on the circuit.
Maximum inlet depression: 250 mm/Hg
Maximum oil speed suction side: 0.5 ÷ 1.5 mt/sec.
Maximum oil speed in outlet side: 3÷8 mt/sec.
Maximum oil speed in return side: 2÷3 mt/sec.
