RG468-61110 PVD-0B-18P Main Hydraulic Pump for Kubota KX030-4 Mini Excavator

1. OEM Part Number & Machine Compatibility

Original pump model: Nachi PVD-0B-18P tandem variable displacement piston pump assembly
Kubota OEM part number: RG468-61110
Exact fit mini excavator model: Kubota KX030-4
Standard mounting flange, input shaft spline and hydraulic port layout enables direct bolt-on replacement for original pump assembly

2. Core Technical Specifications

Structure type: Dual variable axial piston main pump (first stage + second stage) integrated with built-in pilot charge gear pump
Displacement per main pump: 18 cm³/rev, matched to factory hydraulic system design of KX030-4 compact excavator platform

Second Stage Specified Parameters

Rated working pressure (second stage): 22.5 MPa
Maximum relief pressure (second stage): 24.5 MPa
Rated operating speed (second stage): 2300 rpm
Corresponding rated input power (second stage): 16.7 kW
Overall operating speed range precisely calibrated to match rated output of original engine equipped on KX030-4
Mounting bolt layout, input shaft dimension and oil port orientation strictly comply with Kubota OEM dimensional drawings
Pump housing constructed from high-strength ductile iron; internal pistons, valve plates and friction components adopt quenched wear-resistant alloy steel to extend total service lifespan
