Unlike one-size-fits-all universal hydraulic pumps that force DX150-9C 400914-00405B excavators to adapt to mismatched flow rates, the K3V63DT-9NOT is designed exclusively for these B-series models. Its fluid flow is precisely optimized to align with the unique layout of the B-series’ hydraulic system, including the diameter of hoses, the pressure requirements of the arm and bucket cylinders, and the response time of the control valves. This optimization eliminates the “energy waste” common with universal pumps, where excess fluid flow is forced through the system or insufficient flow causes the machine to work harder. In practice, this translates to a 15% reduction in energy loss, which directly cuts fuel consumption for Doosan operators. For a fleet running 5 DX150-9C 400914-00405B excavators—each consuming an average of 12 liters of diesel per hour—this 15% reduction saves 9 liters of diesel per hour across the fleet, or 216 liters per day for a 24-hour operation. Over a month, that’s 6,480 liters of diesel saved, significantly lowering daily operational costs and making the pump 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.
