A10VO601K1DS/53R-VSD46N00 Hydraulic Axial Piston Pumps A10VO18 A10VO28 A10V045 A10VO60 A10V071 Hydraulic Piston Pump

Core Operating Principle: The Swashplate Mechanism

The A10VO18 is a field-proven axial piston, swashplate pump. Multiple pistons in a rotating cylinder block are driven by the input shaft, with stroke length governed by the swashplate angle. An external actuator adjusts this angle on demand, delivering variable flow from zero to full 18 cm³/rev displacement at constant shaft speed. This on-demand principle powers hydraulic systems efficiently. The same design philosophy extends across the A10VO series hydraulic axial piston pumps, including the A10VO28, A10V045, A10VO60, and A10V071, ensuring consistent performance throughout the product family.

Key Technical Data at a Glance

• Displacement: 18 cm³/rev (≈1.10 in³/rev).

• Pressure Rating: Max 350 bar (≈5,075 psi), standard continuous at 280 bar.

• Speed Range: Up to 3000 rpm or higher, depending on control type and porting.

• Defining Feature: A broad range of integrated control options, transforming the pump into a smart, system-optimized component. For higher-flow needs, the series also offers models from A10VO18 through A10V071, with specific configurations such as the A10VO60 1K1DS/53R-VSD46N00 available upon request.

Control Variants: The Intelligence Behind the Power

Choosing the correct control variant is the most critical application decision for the A10VO18. It determines pump behavior and overall system efficiency. Customers seeking alternative configurations may reference models like the A10VO60 1K1DS/53R-VSD46N00, which shares similar control architecture for higher-displacement applications.

Pressure Control (LR, LU, LRC)

• Function: Self-regulating pressure source. Automatically reduces displacement (“de-strokes”) to maintain preset pressure, delivering only minimal flow to compensate for leakage.

• Expert Application: In plastic injection molding, an LRC-controlled A10VO18 provides holding pressure during cooling without engaging a relief valve, cutting energy and heat versus fixed-displacement pumps. This control principle applies across the A10VO series, from the A10VO18 to the larger A10VO60 and A10V071.

Pressure/Flow Compensator (LRDS, LRDF)

• Function: Delivers constant preset flow regardless of load fluctuations (within power limits), combining priority flow control with pressure-limiting protection.

• Expert Application: In industrial surface grinders, an LRDF-controlled A10VO18 maintains steady table feed speed for consistent finish quality. This compensator function is also available on higher-capacity models, including the A10VO60 1K1DS/53R-VSD46N00.

Load-Sensing Control (LRDS with LS port)

• Function: Monitors the highest pressure demand from all active functions via an LS line, delivering only the required flow at a pressure marginally above (Δp) that demand—the peak of multi-function hydraulic efficiency.

• Expert Application: On mobile cranes performing simultaneous boom, telescope, and swing operations, load-sensing A10VO18 automatically provides precise pressure and flow as demanded. The same LS technology is used across the A10VO lineup, from A10VO28 to A10V071, ensuring efficiency regardless of pump size.

Performance Characteristics & Design Advantages

The A10VO18 is trusted by OEMs and rebuilders for proven performance, a reputation shared by the entire A10VO family including the widely specified A10VO60 and A10V071:

• High Power Density: Compact, rugged design delivers exceptional output relative to size and weight—critical for space-limited mobile equipment.

• Superior Efficiency: Precision manufacturing minimizes internal leakage (high volumetric efficiency) and reduces friction (high hydromechanical efficiency), lowering operating costs and waste heat.

• Responsive Control: Integrated controls provide precise, stable, and fast response for smooth, safe machine operation.

• Serviceability: Major sub-assemblies are separable for easy inspection and overhaul. The A10VO60 1K1DS/53R-VSD46N00 and other series models share this service-friendly design.

Common Industrial & Mobile Applications

The A10VO18 offers versatility across sectors, as do the broader A10VO series hydraulic piston pumps—including A10VO28, A10V045, A10VO60, and A10V071:

• Mobile Machinery: Excavators, compact loaders, telehandlers, and small cranes—powering implements, drives, and steering.

• Industrial Production: Injection molding, hydraulic presses, and machine tool auxiliaries (clamping, tool changers) requiring precise, repeatable force.

• Material Processing: Wood chippers, compactors, and balers operating under pulsating loads. For higher-capacity requirements, models such as the A10VO60 1K1DS/53R-VSD46N00 offer increased flow while maintaining the same reliability.
