KYB PSVD2 Series Pump | PSVD2-21E, PSVD2-27E, PSVD2-42, PSVD2-13E | Main Hydraulic Pump for Mini Excavator

KYB PSVD2 Series Hydraulic Main Pump for Mini Excavators

Product Overview: The KYB PSVD2 series stands as the premier high-performance power source for mini and micro excavator hydraulic systems worldwide. Featuring a unique integrated architecture of dual axial piston pumps and multiple auxiliary gear pumps, it is specifically engineered for 1.5 to 8-ton excavators from brands like Sany, Kubota, Yanmar, and Takeuchi. Featured models such as the PSVD2-21E-22 and PSVD2-21E-35 deliver multiple independent hydraulic outputs from a single compact unit, ensuring balanced power distribution and responsive, energy-efficient control during simultaneous functions like traveling, swinging, and boom lifting.

Key Technical Advantages:

• Highly Integrated & Space-Saving: Combines two high-pressure variable piston pumps with auxiliary gear pumps on a single drive shaft, perfectly fitting the constrained engine compartments of compact machinery.

• Precision Power Output: Precision-lapped valve plates ensure exceptional synchronicity during multi-valve operations, resulting in smoother and more agile machine movements.

• Extreme Durability: Built with high-strength cast iron housings and heat-treated rotating groups to withstand frequent load shocks and harsh ambient temperature fluctuations on jobsites.

• Superior Self-Priming at High Speeds: Optimized fluid dynamic design improves filling efficiency at high RPMs, effectively preventing cavitation and extending the service life of internal components.

• 100% OEM Standard Compatibility: Manufactured to strict KYB factory specifications, ensuring splined shafts, mounting flanges, and porting align perfectly for a seamless “drop-in” replacement.
