3. Installation & Operation Requirements
- Hydraulic Fluid: Petroleum-based anti-wear hydraulic oil equivalent to ISO VG-32 or 46; recommended viscosity range is 20~400 mm²/s, temperature range is 0~60 ℃.
- Contamination Control: Maintain oil contamination within NAS Grade 10; suction port requires a ≥100 μm (150 mesh) reservoir filter, return line requires a ≤10 μm line filter.
- Mounting: The filling port should be positioned upwards; use a flexible coupling to avoid bending or thrust stress; maximum permissible shaft misalignment is less than 0.1 mm TIR, maximum misangular is less than 0.2°.
- Suction Pressure: Permissible suction pressure at the inlet port is between -16.7 and +50 kPa; the height of the pump suction port should be within 1 meter from the oil level in the reservoir.
- Drain Piping: Ensure the pressure within the pump housing is ≤0.1 MPa (normal) and ≤0.5 MPa (surge); recommended drain piping inside diameter is ≥16 mm.
4. Additional Information
- Design Feature: Inclined plate design, high volume efficiency, good closure characteristics, small power loss, and reduced oil temperature rise.
- Control Options: Various control types are available, including pressure compensator type, solenoid two-pressure control type, proportional electro-hydraulic load sensing type, etc. (this model adopts pressure compensator control).
- Packaging: Packed in cartons or wooden cases.
- Lead Time: 1~20 pieces (in stock); 20~50 pieces (estimated 5 days); more than 50 pieces (to be negotiated).
