The A4VG71 Hydraulic Pump is one of the most widely used variable displacement axial piston pumps developed by Brueninghaus Hydromatik and now supported under Bosch Rexroth. The A4VG series has established itself as a global industry standard for hydrostatic drive systems in marine, offshore, industrial, construction, mining, and heavy equipment applications.
The A4VG71 model is particularly popular because it offers an excellent balance between hydraulic power output, compact dimensions, fuel efficiency, and reliability. It is frequently installed in marine deck machinery, hydraulic cranes, offshore lifting equipment, winches, cargo handling systems, hydraulic power packs, and industrial hydraulic drives.
For shipowners and marine operators, the A4VG71 provides dependable hydraulic performance while reducing operational downtime. Its proven design and extensive worldwide support network make it one of the most sought-after hydraulic pumps in the marine spare parts market.
SM MARINE SERVICE™ supplies A4VG71 Hydraulic Pumps in New, Used, and Reconditioned condition based on customer requirements and budget.
The A4VG71 is a swashplate-type axial piston variable pump specifically engineered for closed-circuit hydrostatic transmission systems. The pump automatically adjusts flow according to system demand, improving energy efficiency and overall machine performance.
Unlike fixed displacement pumps, the A4VG71 can continuously vary output flow while maintaining stable operating pressure. This allows operators to achieve precise hydraulic control in demanding marine and industrial environments.
The pump is commonly integrated into:
Due to its modular construction, the A4VG71 is also highly serviceable. Most internal components can be replaced or rebuilt without requiring complete pump replacement.
SM MARINE SERVICE™ supports customers worldwide with supply, sourcing, repair, overhaul, and spare parts solutions for A4VG71 hydraulic pumps.
The A4VG71 automatically adjusts displacement according to load requirements. This feature significantly improves energy efficiency and reduces unnecessary hydraulic losses.
The advanced swashplate design enables smooth power transmission while maintaining excellent volumetric and mechanical efficiency throughout the operating range.
The pump delivers high power density while maintaining compact dimensions. This is especially important in marine and offshore installations where available space is often limited.
The A4VG71 has earned a reputation for dependable performance in harsh operating environments including offshore platforms, vessels, cranes, and industrial production facilities.
Various hydraulic, mechanical, and electronic control configurations are available, allowing integration into a wide range of hydraulic systems.
Routine maintenance, troubleshooting, overhaul, and spare part replacement can be carried out efficiently due to the modular design of the pump.
