Frequently Asked Questions
1. What is the A4VSO pump and what are its key features?
The A4VSO is a swashplate-type axial piston variable pump designed for efficient hydrostatic drives in open circuits. Its notable features include excellent suction characteristics, low noise levels, long service life, high power-to-weight ratio, and a modular design.
2. What are the typical applications for A4VSO pumps?
These pumps are widely used in heavy-duty industrial applications such as ceramic presses, refractory material presses, steel and forging equipment, metallurgical machinery, mining machinery, marine machinery, petroleum equipment, engineering machinery, and machine tool control systems.
3. What control options are available for the A4VSO series?
The series offers a comprehensive range of control types including 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.
4. What should be considered for installation and fluid selection?
The pump can be installed in various positions (horizontal or vertical). 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.
