Common frame sizes include A7VKO012 , A7VKO028 , A7VKO055 and A7VKO107 , each built for continuous operation in heavy-duty environments. BAOLILAI produces OEM-compatible units with factory testing; full PDF datasheets and CAD are available at www.baolilai-pump.com and by request at www.baolilai-pump.com/contact_us/ . Each pump is supplied with a one-year warranty . Copyable technical parameter table Model Displacement (cc/rev) Speed range (rpm) Rated pressure (bar) Warranty A7VKO012 12 1500–1800 400–450 1 year A7VKO028 28 1500–1800 400–450 1 year A7VKO055 55 1500–1800 400–450 1 year A7VKO107 107 1500–1800 400–450 1 year Design highlights • Bent-axis axial piston architecture for high volumetric efficiency and low internal leakage. • Hardened rotating group, precision pistons and optimized swashplate reduce wear and heat generation. • Reinforced housings, heavy-duty bearings and optional explosion-resistant variants for hazardous zones. • Surface treatments and special seals available for marine, mining or corrosive environments. • Compact footprint and multiple mounting/shaft options simplify retrofit into planetary gearboxes and OEM drives. Application scenarios and OEM examples The A7VKO series is specified where compact, efficient pumping is required for continuous service: Agricultural machinery: Primary and implement pumps on large tractors and combine harvesters (example OEM sites: www.deere.com , www.agrifac.com ). Models such as the A7VKO012 and A7VKO028 are well suited to implement circuits and steering control. Construction equipment: Main pump and auxiliary pump duties on excavators and pavers—suitable for medium-class excavators and compact wheel loaders (example OEM sites: www.jcb.com ). The A7VKO055 is a common choice where higher flow is needed. Mining and quarrying: High-durability pumps for shuttle conveyors, drilling rigs and support equipment, where A7VKO107 delivers sustained flow at high pressure (example OEM sites: www.komatsu.com , www.liebherr.com ). Engineering & industrial systems: Hydraulic presses, marine winches and material-handling cranes benefit from the A7VKO’s stable pressure control and explosion-proof options (example OEM sites: www.konecranes.com ). System integration guidance Calculate target rpm: rpm ≈ (system flow L/min × 1000) ÷ displacement (cc/rev), then allow margin for volumetric efficiency. Maintain hydraulic fluid cleanliness per OEM ISO targets; fine filtration extends service life of pistons and swashplate. Install oil coolers for sustained high-power cycles; monitor oil temperature and viscosity. Use accumulators or pilot-operated dampers to protect against pressure spikes and transient loads. Confirm shaft/mounting selection at order to avoid retrofit delays. FAQ Q1: Which A7VKO model is best for a medium excavator? A1: For medium excavators requiring a balance of flow and pressure, A7VKO055 is often chosen; final selection should match required actuator speeds and system flow. Q2: Can A7VKO pumps be used in closed-loop hydrostatic drives? A2: Yes—A7VKO units integrate into closed-loop systems when paired with appropriate charge pumps, relief valves and control electronics. Q3: Are explosion-proof options available? A3: Yes. BAOLILAI offers explosion-resistant housings and special seals for hazardous environments; specify at purchase. Q4: Where to download datasheets and request support? A4: Visit www.baolilai-pump.com or request PDFs at www.baolilai-pump.com/contact_us/ . Conclusion The Rexroth A7VKO axial variable piston pump series (A7VKO012, A7VKO028, A7VKO055, A7VKO107) provides reliable, high-pressure pumping for a wide range of industrial and mobile applications. With robust construction, environmental options and BAOLILAI’s one-year warranty, these pumps meet OEM requirements for durability and performance.
