K3VL28 Kawasaki Fan Pump for Excavator spare parts
description
The K3VL28 fan pump adopts Kawasaki classic K3VL series heavy-duty variable piston pump structure, specially upgraded for engineering machinery cooling system working characteristics. Different from ordinary fixed-displacement gear fan pumps, this model supports intelligent variable flow and pressure adjustment, automatically matching output power according to system temperature and load changes to realize on-demand oil supply and energy-saving operation. Equipped with hardened precision piston cylinder assembly, high-strength wear-resistant valve plate, fatigue-resistant swash plate variable mechanism and imported high-temperature aging-resistant sealing components. The internal matching clearance is precisely controlled, with extremely low internal leakage and excellent pressure holding performance. It can maintain stable hydraulic output without pressure attenuation and flow fluctuation under long-term high-temperature and heavy-load cyclic working conditions. The high-rigidity integral cast pump body effectively resists construction vibration, dust erosion and instantaneous hydraulic impact, with strong durability and low failure rate, fully meeting the long-term heavy-duty heat dissipation requirements of mid-to-large excavators.

advantages
- Genuine Kawasaki K3VL28 variable fan pump, professionally calibrated for mid-to-large excavator independent heat dissipation hydraulic system, with accurate variable parameters and stable temperature control logic, ensuring matching cooling power and no overheating failure.
- Intelligent adaptive variable pressure regulation technology automatically adjusts flow and pressure according to equipment load and temperature, effectively solving insufficient fan power under full-load heavy-duty conditions and avoiding energy waste of traditional fixed-displacement pumps.
- High-precision internal matching components minimize internal leakage and pressure fluctuation, ensuring synchronous and stable fan motor speed regulation, no jitter, stalling or speed drop during long-term high-intensity operation.
- Imported high-temperature anti-aging sealing system maintains excellent sealing performance under long-term high-heat and high-pressure working conditions, effectively preventing oil leakage and performance attenuation.
- Reinforced high-rigidity cast pump body has strong anti-vibration, anti-impact and anti-dust erosion capabilities, adapting to harsh working environments such as mines and earthwork sites with ultra-low failure rate.
- Energy-saving variable design optimizes hydraulic output according to actual heat dissipation demand, greatly reducing idle power consumption and improving overall equipment operating economy.
- Standard installation size supports 1:1 non-destructive direct replacement, no modification or complex debugging required, effectively reducing equipment downtime and maintenance costs.
maintenance & replacement tips
- Regularly check the mounting bolts, oil inlet and outlet joints and sealing surfaces of K3VL28 fan pump to eliminate oil leakage risks caused by long-term heavy-load vibration and mechanical impact in complex construction conditions.
- Clean radiator and fan blade dust, sediment and dirt regularly to prevent heat dissipation blockage, avoid long-term overload operation of the variable pump and delay wear and aging of internal precision components.
- Replace hydraulic oil and high-precision filter elements strictly in accordance with equipment official maintenance cycle to prevent hard impurities from scratching precision matching pairs and ensure stable variable pressure and flow output.
- Periodically detect the working pressure, variable response sensitivity and flow stability of the pump body to ensure it operates within the rated range and meets full-load extreme heat dissipation requirements of mid-to-large excavators.
- Avoid long-term extreme high-temperature overload operation and abnormal hydraulic pressure impact to reduce fatigue wear of internal variable mechanism and precision components, extending pump service life.
- Timely replace genuine K3VL28 fan pump when faults such as slow heat dissipation, unstable fan speed, pump body oil leakage and system high temperature alarm occur to restore the energy-saving and high-efficiency cooling performance of the equipment.
