A4VSO180DRG/30L-PPB13N00 German Rexroth piston variable hydraulic pump

The Rexroth A4VSO180DRG/30L-PPB13N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, featuring DRG pressure compensator control with pilot pressure limitation. With a displacement of 180 cm³/r and PPB13 SAE compact flange & ports, the pump maintains a preset system pressure by reducing displacement toward zero once the set pressure is reached, while also allowing remote pressure setpoint adjustment via pilot port X.

The PPB13 porting makes this variant well suited to space-limited hydraulic power units and manifold-mounted skids. It is commonly specified for industrial press HPUs, test benches, and process plant systems where centralized or remotely adjustable pressure control is required. Rated for 350 bar continuous / 400 bar peak.

Compared to standard DR (mechanical spring-only setting), DRG adds pilot pressure capability:

• Maintains constant system pressure by destroking when setpoint is reached
• Pressure setpoint can be remotely adjusted via pilot pressure at port X — no need to manually turn a spring screw
• Allows pressure changeover from a control cabinet, pilot relief valve, or PLC-controlled pilot source
• Built-in pressure limitation for system safety
• Reduces heat generation during pressure-hold conditions

➡ Ideal for central hydraulic stations serving multiple machines or processes with varying pressure requirements.

• Central industrial hydraulic power units (HPU) with remote pressure control
• Stamping / forging press clamp and hold circuits
• Hydraulic test rigs requiring adjustable pressure setpoint
• Plastic injection molding machines (clamp-side auxiliary pump)
• Metal forming and process plant hydraulic systems
• Compact manifold-mounted skids (benefits from PPB13 compact SAE porting)
