Product Description
Excavator Hydraulic Pump K3V63DT-9COS for R130/140-7 31N4-10010
Precision Engineered Main Pump Solution
Unlike universal hydraulic pumps that force R130/140-7 31N4-10010 excavators to cope with mismatched flow rates, the K3V63DT-9COS is a tailor-made solution exclusively for these B-series models. Every aspect of its fluid flow design is precisely optimized to match the unique hydraulic system layout—including hose diameters, pressure demands of arm and bucket cylinders, and response speeds of control valves.
Proven Performance Benefits
This targeted optimization eliminates the energy waste common with universal pumps, where excess fluid circulates unnecessarily or insufficient flow forces equipment to overwork. In real-world operations, this translates to a 15% reduction in energy loss, directly cutting fuel consumption for Doosan operators.
Cost Savings Example: For a fleet of 5 R130/140-7 excavators (each consuming 12 liters of diesel per hour), this 15% saving means:
  • 9 liters of diesel saved per hour across the fleet
  • 216 liters per day for 24-hour operations
  • 6,480 liters per month—significantly reducing operational costs
