Original Kayaba KYB PSVD2 Series Hydraulic Pumps (PSVD2-17E/17E-19 & PSVD2-13E)

(For Yanmar VIO45/VIO55/VIO75 Mini Excavators)

A: These are original Japan KYB (Kayaba) variable displacement axial piston hydraulic main pump assemblies, including two core models:

PSVD2-17E / PSVD2-17E-19: OEM part number B0600-16018, for 3.5–5 ton Yanmar VIO45/VIO50/VIO55.
PSVD2-13E: OEM part number B0600-12003, for 2–3 ton & Yanmar VIO75 mini-excavators.

Both are swash-plate type, with integrated gear pumps (pilot/auxiliary), used for digging, travel, swing, and breaker operations.

Model	Structure	Displacement (cc/rev)	Rated/Max Pressure (MPa)	RPM	Suitable Tonnage	Main Applications
PSVD2-17E/19	Variable piston + fixed gear	17–19	24.5 / 24.5	1500–2500	3.5–5 t	Yanmar VIO45/50/55
PSVD2-13E	Variable piston + fixed gear	~13	24.5 / 24.5	1500–2500	2–3 t / VIO75	Yanmar VIO75, 3-ton class

Swash-plate variable control: Auto-adjusts displacement to load; constant power to avoid engine overload.
High pressure & durability: Valve plate, slipper, cylinder block use wear-resistant alloys; 24.5 MPa continuous.
Multi-circuit: Main piston pump + pilot gear pump; supports simultaneous boom/arm/travel/breaker.
Solenoid functions (17E-19): Travel 2-speed, boom priority, flow merging.
Standard mounting: Direct engine flywheel connection; high efficiency; easy replacement.

PSVD2-17E/19:

Yanmar VIO45, VIO50, VIO55, VIO57; IHI 35/55/60; Kubota KX35/KX40/KX41.
PSVD2-13E:
