4.2 Installation Dimensions
-
Axial Port Type: Fully extended length 195.5 mm (7.70 in), lock nut size 13 mm (0.51 in) hex, suction port diameter 19 mm (0.75 in), mounting hole distance 96 mm (3.78 in) / 114 mm (4.49 in).
-
Side Port Type: Overall length 158 mm (6.22 in), drain port thread same as axial type, other dimensions refer to axial port type.
5. Hydraulic Fluid Requirements
-
Recommended Fluid: Petroleum-based anti-wear hydraulic oil equivalent to ISO VG 32 or 46.
-
Viscosity Range: 20-400 mm²/s (100-1800 SSU) during operation.
-
Operating Temperature Range: 0°C to 60°C (32°F to 140°F).
-
Contamination Control: Maintain fluid cleanliness at NAS Grade 10. Equip suction port with a 100 μm (150 mesh) reservoir filter and return line with a ≤10 μm line filter.
6. Installation & Operation Precautions
-
Drain piping must maintain housing pressure below 0.1 MPa (1 bar) normal and 0.5 MPa (5 bar) surge. Piping length should not exceed 1 m, with the pipe end submerged in oil.
-
Use a flexible coupling to avoid bending or thrust stress. Maximum permissible misalignment is ≤0.1 mm TIR and misangularity ≤0.2°.
-
Permissible suction pressure range: -16.7 kPa to +50 kPa. The pump suction port height should be within 1 m from the reservoir oil level.
-
Bleed air from the pump case and outlet line before initial start-up. An air bleed valve (Model ST1004-*-10*) is recommended.
-
Avoid excessive piping load on suction/discharge ports; use rubber hoses if necessary to reduce noise.
