Product Description

KYB PSVD2 Series Mini Excavator Main Hydraulic Pump

Product Overview: The KYB PSVD2 series is a premier flagship in hydraulic systems for mini excavators globally. Designed as a compact, single-shaft dual-displacement piston pump, the PSVD2 range (covering 21cc, 26cc, and 27cc) is specifically engineered for 2 to 5-ton excavators. It integrates two variable displacement piston pumps and auxiliary gear pumps, perfectly coordinating complex movements such as travel, swing, and bucket operations. Whether it is the PSVD2-21E or the higher-capacity PSVD2-27E, this series is renowned for its high power density and exceptional durability under grueling excavation conditions.

Key Technical Advantages:

  • Advanced Multi-Function Integration: Integrates dual variable pump groups within a single housing, enabling seamless “travel while lifting” or “swing while digging” operations, significantly boosting site productivity.

  • Precise Power Balance Control: The optimized swashplate mechanism ensures that pump output pressure and flow consistently align with the engine’s optimal power curve, delivering maximum breakout force while minimizing fuel consumption.

  • Heavy-Duty Extended Durability: Built for harsh construction environments, featuring reinforced slippers and high-hardness valve plates to maintain peak volumetric efficiency even under continuous high loads and hydraulic shock.

  • OEM-Grade Compatibility: Models such as PSVD2-21E-18 and PSVD2-26E-20 strictly follow the installation standards of major global mini-excavator brands, ensuring perfect alignment of port layouts and spline specifications for seamless replacement.
