YEOSHE V-Series Variable Displacement Axial Piston Pumps | High Pressure High Efficiency, Displacements from 15cc to 70cc.

Industrial-Grade Efficiency for High-Pressure Systems The YEOSHE V-Series is a premier range of axial piston pumps designed for variable displacement applications where precision, energy saving, and thermal management are critical. These pumps feature a high-response swashplate design with a changeable angle, ensuring optimal performance across a wide variety of industrial and mobile applications. Engineered for low noise and high reliability, the V-Series is the professional choice for modern hydraulic power units.

Technical Specifications by Model:

*V50/V70 Nominal Pressure is 175 bar; higher pressure adjustments available on request.

Standard Core Features:

• Pressure Compensation: Type A control automatically adjusts flow to maintain system pressure, reducing power consumption and oil temperature rise.
• Mounting Standards: V15 to V42 utilize SAE A 2-bolt mounts. Larger V50 and V70 models feature standard SAE C 2-bolt or 4-bolt configurations.
• Operational Range: High-speed capability up to 1800 RPM with a minimum operational speed of 500 RPM.
• Low Noise Design: Specifically engineered internal geometry reduces acoustic output even during full-pressure operation.

V-Series Model Available Pressure Ranges, Mounting Flange, Oil Ports and Weight.

Technician’s Advice:

"When selecting a pump from the V-Series, ensure your suction line is adequately sized to prevent cavitation;
These piston pumps are precision-machined and will not tolerate oil starvation.
For all models, the case drain must be connected directly to the reservoir and kept below 2 bar to protect the internal shaft seals.
On initial start-up, you must prime the pump by manually filling the case with clean, filtered hydraulic fluid via the top filling port.
Failure to do so will result in immediate catastrophic failure of the piston shoes and swashplate."
