Designed for heavy-duty field use, the NEWTOP NTDWP30 combines robust diesel power with an engineered pump body to deliver consistent performance in large-volume water transfer. Its durable construction, efficient fuel system and reliable starting capability make it a practical solution for irrigation, emergency drainage and multiple industrial scenarios.
Equipped with the NEWTOP NTDE178F diesel engine, the NTDWP30 delivers a strong 4 kW output, supporting fast, stable pumping across demanding environments. The engine structure features a high-strength 42CrMo forged crankshaft and nitrided thickened gears—components chosen for longevity and stable torque delivery. The BOSCH-based injection system enhances combustion efficiency, helping keep fuel consumption low even under continuous operation.
The pump section is engineered through precision machining and hydrodynamic optimization, enabling the unit to achieve a total head lift of 26 meters, a suction height of up to 8 meters and a discharge capacity of 60 m³/h. A specially reinforced full-frame chassis incorporates a vibration-damping layout that effectively stabilizes the unit during extended use.
With simple manual starting, ease of servicing and durable performance, the NTDWP30 is well suited for agricultural irrigation, firefighting support, flood relief, household water supply and marine transfer tasks. These capabilities also make it a strong option for diesel water pump suppliers and outdoor power equipment dealers looking for a reliable 3-inch diesel pump solution.
