Excavator Hydraulic Pump K3V63DT-9COS for R130/140-7 31N4-10010 MAIN PUMP Cost-Effective Solutions

Product Introduction

Unlike universal hydraulic pumps that adopt a "one-size-fits-all" approach and often 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 detail of its fluid flow design is precisely optimized to match the unique hydraulic system layout of B-series excavators—covering hose diameters, pressure demands of arm and bucket cylinders, and response speeds of control valves. This targeted optimization puts an end to the "energy waste" plaguing universal pumps, where either excess fluid is pushed through the system unnecessarily or insufficient flow forces the machine to overwork. In real-world operations, this translates to a 15% reduction in energy loss, directly cutting fuel consumption for Doosan operators. For a fleet of 5 R130/140-7 31N4-10010 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, and 6,480 liters per month—significantly slashing daily operational costs and making the K3V63DT-9COS a cost-effective long-term investment.

Why Choose TGFQ Over Other Excavator Part Dealers?​

TGFQ stands apart with 3 unique strengths:​

Model-specific know-how: We do more than sell parts—our team can cross-reference part numbers with your excavator’s VIN to ensure a 100% fit (in the last year, we’ve helped over 500 clients avoid delays caused by “wrong parts”).​

Customizable solutions for every client: Whether you’re a small repair shop needing just 1 sample part (we accept orders starting at $50) or a large fleet requiring 100+ engine assemblies (we provide bulk discounts of up to 15%), we adjust to meet your individual needs.​

Post-purchase support services: Beyond delivery, we offer free maintenance handbooks (e.g., “Strategies to Extend Hydraulic Pump Life”) and quarterly check-ins to keep you informed about part upgrades for your machine model.​

With clients in 30+ countries (including repeat customers like a Southeast Asian construction firm that has collaborated with us for 10 years), TGFQ delivers more than just parts—it delivers reliable support you can trust.
