Product details
I. Brand Overview
REXROTH is a world-renowned top-tier industrial hydraulic brand. The LA1VO035DRS0C200 belongs to the A1VO series of variable-displacement axial piston pumps. It is widely used in both closed and open hydraulic systems of construction machinery and mobile equipment. It can deliver precisely controllable flow and pressure for the complete machine hydraulic circuits, perfectly adapting to heavy-duty fluctuating working conditions.
II. Segment-by-Segment Model Coding Definition (per REXROTH A1VO Naming Standard)
Code Segment Detailed Definition
LA1VO Product series: Lightweight variable axial piston pump of A1VO line; L denotes lightweight structural design tailored for mobile machinery
035 Nominal displacement: 35mL/r
DRS Control mode: Dual electric variable control with pressure and flow regulation (DR constant pressure control + S proportional electronic adjustment), which can automatically adjust displacement based on hydraulic system loads
0 Basic version for mounting specifications, flange and shaft configurations
C Specification for medium adaptability and housing pressure resistance, applicable to conventional anti-wear hydraulic oil operating conditions
200 Custom code for structural iteration version, rotation direction and oil port layout
III. Core Technical Parameters
1. Structure type: Swashplate-type variable-displacement axial piston pump
2. Geometric displacement: 35 mL/rev
3. Maximum rated pressure: 35MPa, maximum instantaneous peak pressure up to 40MPa
4. Recommended rotating speed range: 800–2600rpm, maximum instantaneous rotating speed shall not exceed 2800rpm
5. Control performance: DR constant pressure feedback plus proportional electronic adjustment. It maintains constant pressure of the hydraulic system and realizes stepless regulation of output flow via electrical signals
6. Compatible medium: HLP anti-wear hydraulic oil, kinematic viscosity 10–46mm²/s, operating temperature ranging from -20℃ to +80℃
7. Volumetric efficiency: ≥94% under rated working conditions, which greatly reduces internal leakage and heat generation of the hydraulic system
8. Mounting type: SAE standard flange mounting, with flat key or spline drive options, suitable for direct connection with gearboxes of mobile machinery
IV. Structure and Working Principle
Variable displacement is achieved by adjusting the swashplate inclination angle to alter the reciprocating stroke of pistons:
The drive shaft rotates the cylinder block and pistons synchronously, and the pistons complete oil suction and pressurization cycles with the cooperation of the valve plate. The DR pressure feedback module collects outlet oil pressure of the hydraulic system in real time and adjusts the swashplate angle automatically to stabilize system pressure. With additional S electronic control signals, remote precise control of displacement output can be realized to match flow demands of travel and working devices under different working conditions, eliminate redundant overflow energy consumption and improve the energy-saving performance of the entire hydraulic system.
V. Core Product Advantages
1. Dual-mode precise regulation: Combined mechanical constant pressure and electronic proportional control ensures stable system pressure and intelligent remote flow adjustment, making it ideal for highly automated hydraulic systems
2. High pressure resistance and superior reliability: Adopting high-strength cylinder block and spherical valve plate design, it boasts strong shock resistance for heavy-duty fluctuating scenarios such as excavators and concrete pump trucks
3. Energy conservation and consumption reduction: On-demand variable output automatically lowers displacement under no-load and light-load conditions, remarkably cutting heat generation and fuel consumption of the hydraulic system
4. Excellent interchangeability: Standardized interfaces of the A1VO series allow retrofitting and replacement of existing hydraulic power stations or travel pumps between versions with the same displacement but different control modes
5. Low noise and long service life: Precision piston assemblies and vibration-damping structures minimize flow pulsation, extending the maintenance cycle of the whole hydraulic system
VI. Typical Application Scenarios
- Main hydraulic systems of small and medium-sized excavators
- Power units for concrete mixer trucks and truck-mounted concrete pumps
- Hydraulic systems for aerial work platforms and mobile lifting equipment
- Travel and working circuits of large agricultural harvesters and silage harvesters
- Industrial mobile hydraulic power stations and light mining tunneling equipment
VII. Key Installation & Operation Guidelines
1. Keep the coaxiality between the pump shaft and driving end no more than 0.03mm. Eccentricity will trigger vibration and pressure fluctuation and undermine the stability of the hydraulic system
2. Equip the suction pipeline with filters of no less than 10μm precision, and limit inlet vacuum within -0.02MPa to avoid cavitation damage to piston assemblies
3. Match electric control signals strictly with driver parameters, follow original factory pressure setting ranges, and refrain from forced overpressure adjustment to protect downstream components including hydraulic valves and cylinders
4. Fully vent trapped air during initial startup; prolonged high-speed idling without load is prohibited. Replace hydraulic fluid and sealing kits regularly to sustain long-term stable operation of the hydraulic system
