Model Series: A11VO series swashplate-type variable displacement piston pumps with an open circuit design, covering displacements from 40 to 260 cm³/rev.
Working Pressure:
Rated Pressure: 350 bar (continuous working conditions)
Peak Pressure: 400 bar (short-term working conditions)
Variable Control: Supports multiple adjustment methods (such as power control, pressure compensation), allowing for real-time external adjustment of the power setting value to meet the requirements of complex working conditions.
Drive Configuration: The through-shaft drive function is optional. It can be connected in series with piston pumps or gear pumps of the same specification to expand the system functions.
Key Design Features
Application Fields: Specifically designed for high-pressure systems of construction machinery. Typical scenarios include concrete pump trucks, cranes, scraper machinery, and mining equipment, meeting the needs of high-load and high-frequency operations.
Structural Optimization: The swashplate-type axial design enables stepless adjustment of the flow rate (from 0 to the maximum displacement), improving the system's energy efficiency; the self-priming ability is suitable for configurations with pressurized oil tanks or auxiliary booster pumps.
Sealing and Materials: Heavy-duty bearings and wear-resistant coatings are used to ensure a long service life; the oil compatibility complies with the ISO VG 46 or equivalent hydraulic oil standards.
