In the world of heavy machinery, reliable and efficient hydraulic components are vital. One such component that plays a crucial role in power transmission and motion control is the axial piston pump. Among the many models available, the A2V250 Rexroth hydraulic pump stands out due to its proven track record in high-pressure systems.
In this article, we explore the benefits, functionality, and practical applications of the A2V500 remanufactured pump, why remanufactured versions are a smart investment, and what to consider when sourcing one.
What Is a Rexroth A2V500 Hydraulic Piston Pump?
The A2V500 hydraulic piston pump is an open circuit piston pump developed by Rexroth, a brand under Bosch Rexroth, known for its engineering excellence. These pumps are widely used in:
Construction machinery
Industrial equipment
Mining and tunneling systems
Marine applications
These pumps operate with maximum power density, making them ideal for demanding hydraulic systems.
Is a Remanufactured A2V250 Worth It?
Remanufactured hydraulic pumps provide a cost-effective and eco-friendly solution without sacrificing performance.
Key Benefits
Cost Savings
A remanufactured A2V500 Rexroth pump costs significantly less than a new one, often 30–50% cheaper.
Reliable Output
These pumps are rebuilt using OEM specifications, with worn parts replaced and tolerances restored.
Environmentally Friendly
Reusing core components reduces environmental waste and lowers carbon footprint.
Shorter Lead Times
New OEM pumps may have long lead times. Remanufactured pumps are often in stock and ready to ship.
Inside the Remanufacturing Process
The remanufacturing process for an A2V500 pump involves strict quality control and precision engineering.
Step-by-Step Overview
Core Evaluation
The original A2V500 or A2V250 pump is carefully inspected to determine viability.
Disassembly and Cleaning
The pump is completely disassembled and cleaned using ultrasonic and chemical treatments.
Component Replacement
Bearings, seals, pistons, and worn internal components are replaced with new or OEM-equivalent parts.
Machining and Reconditioning
Cylinder blocks, swash plates, and other critical parts are machined back to original tolerances.
Assembly and Testing
The pump is reassembled and undergoes hydraulic bench testing to ensure flow, pressure, and efficiency match OEM specs.
Note: Reputable remanufacturers offer warranty coverage.
Remanufactured A2V500 Pump Efficiency
In most cases, a remanufactured A2V500 pump delivers identical performance to a new unit.
Feature New A2V500 Pump Remanufactured A2V500
Pressure Rating 400 bar 400 bar
Flow Capacity 500 cm³/rev 500 cm³/rev
Efficiency 90–92% 88–91%
Warranty 12–24 months 6–12 months (typical)
Cost $$$$ $$
Unless your application demands brand-new components, reman is often the smarter choice.
Applications of Reman A2V Pumps
The A2V series, including both A2V250 and A2V500, are used in demanding hydraulic systems due to their power output.
Common Use Cases:
Excavators and Earthmoving Equipment
Drilling Rigs
Underground Mining Loaders
Hydraulic Winch Drives
Offshore Cranes
Marine Propulsion Systems
If your equipment has been A2V250 Rexroth Pump running on an OEM A2V500 pump, a remanufactured equivalent is often a drop-in replacement with minimal downtime.
Evaluating Reman A2V500 Sellers
Not all remanufactured pumps are created equal. Here’s how to find a trusted supplier:
ISO or OEM-Certified Facilities
Ensure they follow strict rebuild protocols.
Test Reports & Certifications
Ask for flow bench test results.
Warranty Coverage
At least 6–12 months is standard.
In-House Rebuild vs. Outsourcing
In-house rebuilders have better quality control.
Global Shipping and Support
Make sure they can ship quickly and offer post-sale technical assistance.
