Rexroth A2F is a series of axial piston metering pumps produced by Bosch Rexroth, designed for high-pressure hydraulic applications. These pumps operate on the bent axis principle, ensuring efficient power transmission and compact design.
Main features of Rexroth A2F piston pumps
Fixed displacement - Provides steady flow, which is ideal for use in stable hydraulic power applications.
Bent axis design - Provides high efficiency, long life and compactness.
High working pressure - Can tolerate pressures of up to 450 bar, with reliability in adverse conditions.
Range of sizes - There are several displacements from 5cc to 1000cc per revolution to meet the range of various flow demands.

A2F piston pump structure accessories combination?
Efficient power transmission - low energy loss due to optimized internal design.
Robust structure - high-strength materials and precision manufacturing for long service life.
The structure of the Rexroth A2F axial piston metering pump is composed of a number of key components, each of which plays an important role in the hydraulic transmission process. The following are the main structural components and their functions of the A2F series piston pump:
1. Main structure
Pump Housing:
Made of high-strength cast iron or steel, resistant to high pressure, protecting internal components.
End Cover:
Closes one end of the pump body to ensure sealing and provide installation interface.
2. Transmission assembly
Drive Shaft:
Connects to the power source (such as motor, engine), transmits rotational force to drive the piston assembly.
The shaft end can be splined or keyed.
Bearings:
High-load rolling bearings or sliding bearings ensure smooth operation of the drive shaft and reduce friction.
Cylinder Block / Barrel:
Axially arranged plungers reciprocate in the cylinder block to achieve the suction and discharge of hydraulic oil.
3. Hydraulic components
Piston:
Main working element, pushing the hydraulic oil to flow under high pressure.
Adopt high-precision grinding to ensure sealing and durability.
Valve Plate / Port Plate:
Control the flow direction of oil, separate the high-pressure area and the low-pressure area, and ensure efficient fluid switching.
Retainer Plate:
Keep the plunger in the correct position to ensure stable operation.
Swash Plate (applicable to some variable pumps)
A2F is a fixed displacement pump, which usually adopts a fixed-angle inclined axis design, that is, a bent axis structure, to ensure constant displacement.
4. Sealing and lubrication
High-Pressure Seals:
Prevent hydraulic oil leakage and improve sealing performance.
O-Rings:
Sealing rings in key parts to enhance pressure resistance and sealing.
Lubrication Channels:
Bearings and plungers require oil lubrication to reduce wear and extend service life.
5. Mounting and Interfaces
Mounting Flange:
Easy to install on equipment, usually in accordance with SAE or ISO standards.
Inlet / Outlet Ports:
Connect hydraulic lines to ensure oil flow.
