Kawasaki K5V140DTP-9N01 Main Hydraulic Pump Assembly

The Kawasaki K5V140DTP-9N01 is a high-performance tandem axial piston pump utilizing a swash plate design for variable displacement control. It features a nominal displacement of 140 cm³/rev per section, delivering a combined flow capacity suitable for 30-ton class hydraulic excavators. The pump is rated for a continuous operating pressure of 34.3 MPa (343 bar) with a peak pressure capability of 39.2 MPa (392 bar). This unit serves as a direct replacement for main hydraulic systems in crawler excavators requiring twin-pump configuration for independent travel and implement circuits. The 9N01 designation identifies the specific regulator, shaft, and porting configuration calibrated for Doosan DX300-7 and Daewoo Solar 300LC-V platforms. It incorporates pressure compensation, flow control, and power limitation control options. The pump housing is constructed from high-strength cast iron with hardened steel rotating group components including cylinder block, pistons, and valve plate, ensuring durability under high-cycle construction machinery duty cycles. OEM cross-references include Doosan K1006550C, 400914-00394B, and 400914-00393A; Komatsu 708-2L-00112; Volvo VOE14521441; Sany 60017767; and New Holland 72208819. Compatible with aftermarket repair kits covering cylinder block, valve plate, seal kits, and rotary group assemblies.
