Original KYB PSVD2-17E Main Pump with Solenoid Valve
Product Introduction
The Original KYB PSVD2-17E Main Pump with Solenoid Valve is a professional variable hydraulic piston pump manufactured by KYB Japan. As the central power supply of a complete construction machinery hydraulic system, this integrated hydraulic pump combines the main pump body and proportional solenoid valve as one unit. It realizes automatic power regulation according to working loads, ensuring efficient and steady operation of the whole hydraulic system, and is a standard OEM fitting for mini excavators.
Model Interpretation
- PSVD2: KYB exclusive swashplate axial piston pump series, specially customized for light-duty mini excavator hydraulic drive
- 17E: Nominal geometric displacement: 17 cc/rev, calibrated to match the power demand of 1.5–3 ton mini excavator hydraulic system
- With Solenoid Valve: Built-in electric proportional solenoid control valve, responsible for signal feedback and displacement adjustment of the hydraulic pump
- Original KYB: Full genuine assembly including cylinder block, pistons, valve plate, drive shaft and solenoid assembly, all original factory components

Product Highlights
1. Integrated design of main pump and solenoid valve simplifies piping layout of the hydraulic system, cuts down leakage points and installation time
2. The matched solenoid valve dynamically adjusts pump output flow and power to match real-time loads, avoiding engine stalling and improving energy utilization of the hydraulic system
3. Precision original internal parts guarantee low noise, small flow pulsation and outstanding durability under frequent impact and cyclic working conditions
4. Fully interchangeable with OEM old pumps, direct replacement without modifying the existing hydraulic system structure
Application Range
This genuine KYB PSVD2-17E main hydraulic pump with solenoid valve is widely installed on 1.5t, 2t, 2.5t and 3-ton mini excavators. It acts as the primary power source for the traveling mechanism and working attachment hydraulic system.
