Product Overview

The A10VG series variable displacement pump is a premium Hydraulic piston pump developed by Bosch Rexroth, serving as the core power source of a full closed-loop hydraulic system. As a professional heavy-duty hydraulic pump tailored for hydrostatic transmission, it adopts swashplate axial piston structure, specially configured to match hydraulic motors and construct complete closed-circuit hydraulic system for mobile engineering machinery, realizing stepless speed regulation, forward-reverse switching and hydraulic braking in one integrated unit .

Core Structural Principle

This classic Hydraulic piston pump changes the swashplate swing angle to adjust geometric displacement, so the output flow can be infinitely regulated from 0 to maximum value. When the swashplate passes the neutral position, the oil supply direction reverses automatically, simplifying the valve layout of the whole hydraulic system without extra directional control valves. Built-in integrated charge pump replenishes leaked hydraulic oil and maintains pre-charge pressure inside the closed hydraulic system, eliminating the need for an auxiliary independent hydraulic pump.

Key Technical Parameters

1. Product Type: Swashplate variable Hydraulic piston pump, high-pressure industrial hydraulic pump

2. Common Frame Sizes: A10VG18 / 28 / 45 / 63 cc/rev

3. Nominal Working Pressure: 300 bar; Peak Instant Pressure: 350 bar, perfectly fit high-load closed hydraulic system

4. Max Rated Speed: 3200 rpm

5. Supporting Medium: Anti-wear hydraulic oil for high-pressure hydraulic system

6. Built-in Components: High-pressure relief valves, shuttle hot-oil flushing valves, charge pressure regulating valve, all integrated to protect the whole hydraulic system from overload and oil overheating damage

Outstanding Advantages

1. Compact integrated design reduces piping and installation space of the hydraulic system, lowering overall assembly cost

2. Multiple control options (hydraulic servo control, electric proportional EPC control, manual control) to meet automatic regulation demands of diversified hydraulic system layouts

3. Low vibration and low pulsation output stabilize pressure delivery for the closed hydraulic system, extending service life of matched hydraulic motors and actuators

4. Robust cast iron housing and hardened piston assembly adapt to harsh construction site conditions, guaranteeing long continuous running of the whole hydraulic system

Main Application Scenarios

This reliable Hydraulic piston pump (professional closed-circuit hydraulic pump) is widely assembled into walking drive hydraulic system of:

- Road rollers, asphalt pavers, wheel loaders and other construction machinery full-hydrostatic travel hydraulic system

- Large agricultural harvesters, tractors farm working drive hydraulic system

- Aerial work platforms, rough-terrain forklifts material handling closed-loop hydraulic system

- Sanitation vehicles, small mining vehicles all-hydraulic walking hydraulic system
