Types of Used KOMATSU Hydraulic Pumps in Stock

Used KOMATSU Travel Hydraulic Pump

Used KOMATSU travel hydraulic pumps convert hydraulic energy into linear movement for the tracks or wheels of equipment. These essential components fit mini excavators PC27 through PC800, crawler excavators, and WB series backhoe loaders. Power transmission is achieved via oil pressure generated by the main pump, allowing precise movement even on challenging terrain. Our catalog’s used travel pumps undergo complete refurbishment including replacement of seals, pistons, and worn valves. Each pump is bench tested to verify operating pressure, rated flow, and leak tightness. Genuine parts ensure perfect compatibility with KOMATSU’s complex hydraulic circuits. Our stock covers all models: PC35, PC50, PC75, PC130, PC200, and WB93, WB97 backhoes. These rebuilt pumps deliver like-new performance at a reduced cost.

Used KOMATSU Steering Hydraulic Pump

The used KOMATSU steering hydraulic pump provides hydraulic power assistance to the steering system, easing maneuvering of heavy machinery. This specialized pump generates the necessary pressure at the steering cylinder, reducing operator effort during direction changes. KOMATSU backhoe loaders and wheeled excavators use high-pressure steering pumps capable of up to 200 bars. Our range includes steering pumps for WB, PW, and WA series. Each unit undergoes thorough inspection including flow rate, maximum pressure, and check valve function. Seals and packing are systematically replaced to guarantee leak-free operation. These refurbished pumps meet factory specifications for precise and responsive steering. Installation requires a complete purge of the steering hydraulic circuit to eliminate air that could impair performance.

Used KOMATSU Swing Hydraulic Pump

Used KOMATSU swing hydraulic pumps power the slewing motors of hydraulic and mini excavators, enabling 360° rotation of the cab and attachments. These specialized pumps deliver high torque at low speed to ensure smooth and controlled rotation movements. The complex hydraulic control systems of KOMATSU machinery require precisely calibrated swing pumps to maintain optimal performance. Our catalog offers used swing pumps for all models: PC27, PC30, PC35, PC45, PC50, PC75, PC130, PC200, PC240, PC290, and PC340. Each swing pump is refurbished with replacement of pistons, seals, and internal distributors. Bench tests verify flow, operating pressure, and leak absence. Genuine components ensure precise, gradual rotation essential for earthmoving and handling operations. Installation requires careful pressure adjustments to optimize swing performance.

Used KOMATSU Main Hydraulic Pump

The used KOMATSU main hydraulic pump is the heart of the hydraulic system in construction machinery, simultaneously powering all circuits: boom, arm, bucket, swing, and travel. These variable displacement pumps use a swash plate to automatically adjust flow to meet each function’s demand. KOMATSU technology integrates advanced electronic control that optimizes energy consumption while maintaining maximum performance. Our stock includes main pumps for mini excavators PC27 to PC50, mid-size excavators PC130 to PC240, and large excavators PC290 to PC800. Each unit is fully refurbished, replacing the barrel, pistons, swash plate, and servos. Rigorous bench tests verify maximum pressure (up to 350 bars), rated flow, and automatic control. These refurbished genuine parts ensure optimal hydraulic performance and maximum longevity for your most heavily used KOMATSU machines.

Used KOMATSU Secondary Hydraulic Pump

Used KOMATSU secondary hydraulic pumps complement the main hydraulic system by powering auxiliary functions: cooling fans, feed pumps, control circuits, and optional accessories. These fixed or variable displacement pumps, depending on model, maintain constant pressure for peripheral equipment. Secondary pumps’ reliability ensures overall machine function, including engine cooling and circuit lubrication. Our range covers secondary pumps for all KOMATSU equipment: mini excavators, crawler excavators, backhoe loaders, and wheel loaders. Each secondary pump is refurbished according to manufacturer standards with replacement of wear parts: seals, bearings, and check valves. Quality checks include flow, operating pressure, and leak tightness. These refurbished original components sustain optimal auxiliary performance and extend your KOMATSU equipment’s service life. Installation requires special attention to connections and circuit purging to prevent contamination.

Common Issues, Adjustment and Hydraulic Pump Repair

KOMATSU hydraulic pumps exhibit typical problems linked to their complex hydraulic regulation, especially on mini excavators and mid-size models after 5,000 hours of operation. Common symptoms include reduced hydraulic power, a diesel engine straining and stalling risk, and slowed hydraulic movements, particularly when hot. These malfunctions often stem from regulation issues specific to KOMATSU pumps, requiring specialized technical expertise for diagnosis and repair. Adjusting KOMATSU hydraulic pumps demands specialized skills as few hydraulics technicians master this complex technology. Services include servo control checks, regulation pressure verification, and electronic parameter tuning. Professional repair restores original performance while avoiding costly new-pump replacements, often an uneconomical approach.
