The NEWTOP NTDWP20H is a 2-inch diesel high pressure fire water pump designed around stronger suction capability. With 36m³/h maximum discharge capacity, 70m Max. head lift, and 8m maximum suction head, it is suitable for users who need to draw water from lower, deeper, or less convenient water sources while maintaining compact hose connection and reliable pressure output.
The NTDWP20H is different from the CI diesel models because its main advantage is suction performance. With an 8m maximum suction head, this 2-inch diesel high pressure pump is useful when water must be drawn from lower or harder-to-access water sources.
Although it uses a 2-inch port, its 36m³/h maximum discharge capacity is strong for this size class. Together with 70m Max. head lift, the model provides a practical balance of suction, pressure, and flow for emergency water transfer and irrigation work.
Its NTDE186F diesel engine delivers 6.3kW rated power and supports 2.6 hours continuous working period with a 5.5L fuel tank. This makes the NTDWP20H a good choice for users who want a compact diesel high-pressure pump but need stronger intake capability than the standard CI models.
