A10VSO71 Hydraulic Pump for Plastic Injection Machine High Pressure Piston Pump Replacement

Product Overview:
The A10VSO71 is a high-performance swashplate design axial piston pump from the renowned Rexroth A10VSO series. Specifically engineered for open circuit hydraulic systems, this variable pump delivers exceptional reliability, efficient operation, and precise control under demanding conditions . With a displacement of 71 cm³/rev and multiple advanced control options, it provides stepless flow adjustment for a wide range of medium-pressure industrial and mobile applications . This unit is a direct, high-quality replacement solution for original Rexroth equipment.

Technical Specifications:

Core Features:

• Robust Cast Iron Construction: High-strength cast iron housing provides 30% greater wear resistance than standard alloys, excellent vibration damping, and superior durability in harsh environments .

• Swashplate Design: The proven swashplate design allows for stepless variable displacement by adjusting the swashplate angle, enabling seamless transition between zero and maximum flow .

• Stepless Variable Displacement: Flow is proportional to drive speed and displacement, adjustable steplessly from maximum down to zero via the swashplate angle, offering precise flow matching to reduce energy consumption and heat generation .

• Multiple Control Options: Wide variety of controls available including pressure control (DR), load sensing (DFR/DFR1), power control (DFLR), and electro-proportional (ED) to suit specific application needs .

• Excellent Suction Characteristics: Superior self-priming performance ensures reliable operation even in demanding conditions and at higher speeds, minimizing cavitation risks .

• 100% Through-Drive Capability: Universal through-drive design allows mounting of additional pumps up to the same nominal size for multi-circuit systems, enabling flexible and space-saving system configurations .

• Low Noise Operation: Optimized design ensures low noise levels during operation, contributing to a more comfortable working environment .

• Short Control Response Times: Controls with rapid response times ensure precise operations and better handling in dynamic system conditions .

• High Power-to-Weight Ratio: Compact construction delivers impressive power density, ideal for space-constrained applications .

• Advanced Surface Treatments: Nitriding, hard chrome plating, and ceramic coatings on high-wear surfaces provide exceptional resistance to corrosion, abrasion, and thermal degradation .
