Rexroth A4VG hydraulic pump for Mecalac Ahlmann AS45 wheel loader 23104045 5350265 5350135 5350181 23112758 23106492

The Rexroth A4VG series axial piston variable displacement pump is a high-performance hydraulic power unit specifically engineered for demanding construction equipment like the Mecalac Ahlmann AS45 wheel loader. In this application, the pump serves as the core of the machine's closed-circuit hydrostatic transmission system, delivering the precise, high-power fluid flow required for propulsion and primary implement functions.

This pump is characterized by its robust swashplate design and variable displacement capability, which allows for infinite control of output flow and pressure. It is typically configured as a main pump, often in a dual configuration (e.g., A4VG...EP2), providing independent circuits for travel drives and the hydraulic system. Key features that make it ideal for the AS45 include its exceptional power density, high overall efficiency (reducing fuel consumption and heat generation), and reliable control through integrated electro-hydraulic or direct hydraulic displacement controls. These enable smooth, responsive, and energy-efficient operation of the loader under varying load conditions, from digging and lifting to high-speed travel.

The pump's design ensures high pressure ratings (up to 450 bar and beyond), excellent contamination resistance, and long service life—critical for the harsh, high-cyclic duty cycles of a wheel loader. In summary, the Rexroth A4VG pump provides the AS45 with the intelligent, powerful, and efficient hydraulic power necessary for optimal productivity, maneuverability, and reliability in intensive material handling operations.

Q1: What is the primary function of the Rexroth A4VG pump in the Mecalac AS45 wheel loader?

A1: Its primary function is to act as the core power unit for the machine's closed-circuit hydrostatic transmission system. It generates the high-power, precisely controlled hydraulic flow needed for both the vehicle's propulsion and the operation of its primary work implements (e.g., the loader mechanism).

Q2: Why is the A4VG pump's high overall efficiency particularly important for an application like the AS45?

A2: High efficiency is crucial for reducing fuel consumption and minimizing heat generation. In a wheel loader undergoing intense, cyclical work (digging, lifting, traveling), improved efficiency directly lowers operating costs, increases performance stability by preventing overheating, and extends the life of the entire hydraulic system.

Q3:What is the price and delivery time of the Rexroth A4VG pump for Mecalac Ahlmann wheel loader？

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
