Aftermarket High Quality Kawasaki K3V63DT-HNOV Main Hydraulic Pump 2401-9236 2401-9236B for Doosan Daewoo Solar 130LC-V 140LC-V 150LC-V 155LC-V S150LC-7B DH150LC-7 Excavator

1. OEM Part Number & Machine Compatibility
Original pump model: Kawasaki K3V63DT-HNOV tandem variable displacement axial piston pump assembly
Doosan OEM interchange part numbers: 2401-9236, 2401-9236B
Fully compatible excavator models: Daewoo Solar 130LC-V, 140LC-V, 150LC-V, 155LC-V, S150LC-7B, DH150LC-7 midi excavator
Two part numbers are supersession upgrade versions, identical mounting flange, input shaft spline, hydraulic port layout and internal hydraulic calibration; fully cross-replaceable direct bolt-on aftermarket replacement without modification
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: 63 cm³/rev, perfectly matched to factory load-sensing hydraulic system configuration of 13–15 ton Doosan/Daewoo midi excavator platform
Second Stage Specified Parameters
Rated working pressure (second stage): 32.4 MPa
Maximum relief pressure (second stage): 34.3 MPa
Rated operating speed (second stage): 2200 rpm
Corresponding rated input power (second stage): 68.6 kW
Overall working speed range precisely calibrated to match rated output of original DB58 engine equipped on these excavator models
Mounting bolt layout, input shaft spline dimension and hydraulic port positioning strictly comply with Doosan OEM dimensional drawings
Pump housing adopts high-strength ductile iron; internal pistons, valve plates and friction wear components use quenched wear-resistant alloy steel to improve abrasion resistance and extend overall service life
3. Internal Structure & Functional Introduction
Dual main piston pumps generate high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing compound working movements
Integrated pilot gear pump supplies stable low-pressure oil for pilot control circuits and system hydraulic oil replenishment
Built-in total power matching regulator automatically adjusts total pump flow output responding to real-time load changes, preventing engine stall under heavy digging and loading conditions
Optimized tandem compact layout fits neatly inside the designated hydraulic compartment of Solar 130/140/150-V and DH150LC-7 series excavators
Built-in anti-shock relief valve reduces hydraulic impact, effectively protect pump core components during frequent compound actions
