Frequently Asked Questions
What control options are available for the A4VSO series?
The series offers a comprehensive range of control types. The most common include DR/DRG for constant pressure control, LR for hyperbolic (constant) power control, and EO2 for electro-proportional control. Other options include manual (MA), hydraulic (HW, HM, HS, HD), and electronic (EM, EO) controls, providing flexibility for various system requirements.
What should be considered for installation and fluid selection?
The pump can be installed in various positions (horizontal or vertical). For vertical installation (shaft up), bearing flushing is recommended to lubricate the front bearing. The recommended optimal viscosity range for the hydraulic fluid is 16-36 mm²/s. Acceptable fluids include mineral oils and water-glycol, with a required cleanliness level of at least NAS 9级 (ISO 18/15). The operating temperature range is -25°C to +90°C.
What are the different series within A4VSO?
The pumps are categorized into series, primarily Series 1, 3, 10, 11, and 30, which can relate to design iterations, pressure capabilities, or specific application focuses.
