Product Description
Rexroth A10VD43 Series Tandem Hydraulic Main Pumps for Excavators
Product Overview: The Rexroth A10VD43 series is a specialized tandem variable displacement piston pump engineered for mini-excavators and mobile machinery. Serving as the core power heart for legendary models like the CAT (Caterpillar) 307 and E70B, this pump features a dual-axial piston architecture that delivers independent, high-efficiency hydraulic power for travel, swing, and boom operations. Featured models include the A10VD43SR1RS5 and A10VDL21SR1RS5-993-1. Its compact design and superior power-matching logic ensure excellent coordination of compound movements during complex earthmoving tasks.
Key Technical Advantages:
Specialized Tandem Design: Integrates two 43cc rotating groups within a single housing, utilizing advanced power distribution logic to provide relentless hydraulic force under high-load conditions.
Precise Power Control: Equipped with highly sensitive regulators that modulate displacement in real-time based on engine speed and load variations, significantly boosting fuel economy.
Superior Compatibility: Mounting dimensions and technical specifications strictly adhere to OEM standards for the CAT 307 and E70B, allowing for direct “drop-in” replacement without modifications.
High-Pressure Capability: Rated for continuous operation at 250 Bar (3625 PSI) with peak capabilities up to 350 Bar (5100 PSI), ensuring maximum breakout force for hard digging.
