1. Structural Requirements: The pump unit consists of a two-stage or multi-stage centrifugal water pump and a four-stroke air-cooled gasoline engine. The engine power shall be no less than 4 kW, and the built-in fuel tank capacity shall be ≥4.5L. 2. Starting Method: Manual start. ▲3. Operation and Shutdown Performance: The water pump shall be able to operate at high speed for more than 10 minutes with the outlet valve closed. ▲4. The water pump shall undergo a strength test under conditions of ≥1.2MPa pressure for a test duration of ≥24 hours. Continuous testing is not required; each test segment shall be no less than 6 hours. After the ≥24-hour test, the water pump shall start normally, and its parameters shall be within normal limits. ▲5. Structural Requirements: The gearbox shall be oil-free and maintenance-free. 6. The engine shall have an automatic shutdown function for lubrication protection. 7. The pump unit shall operate normally under conditions of 15° lateral and longitudinal tilt. ▲8. Manual vacuum diaphragm type priming; maximum priming vacuum ≥85kPa. 9. The weight of the single pump unit shall be ≤28kg. 10. Inlet diameter: 50mm, outlet diameter: 40mm. 11. The pump unit can be configured in series, parallel, or series-parallel arrangements. ▲12. Maximum pressure ≥1.8MPa; maximum flow rate ≥390L/min; 13. Head ≥180m. ▲14. At a pressure of 0.6MPa, the flow rate shall be ≥270L/min; at a pressure of 1.1MPa, the flow rate shall be ≥120L/min; at a pressure of 1.4MPa, the flow rate shall be ≥55L/min; 15. Maximum suction lift ≥6m. 16. Structural Requirements: Equipped with a 3/8", 1/4", and fan-shaped three-hole integrated spray gun. 17. Water pump configuration requirements: 1 three-hole integrated DC spray gun, 1 water mist spray gun, 1 check valve, 1 three-way valve, 1 foot valve, 1 water stop clamp, 2 hose wrenches, 1 relay adapter, 1 portable carrying bag, 1 red lightweight suction hose, 300 meters (10 sections) of 1.5-inch polyester filament PU-lined fire hose (specifications 30-40-30), 3 stainless steel frame hose backpacks, 1 set of special tools, and 1 high-grade aluminum alloy packaging case.

This high-lift pump is a pressure-boosting device specifically designed for forest firefighting water supply scenarios. Its core function is to ensure rapid and stable delivery of firefighting water to the scene when water source pressure is insufficient, utilizing multi-stage centrifugal pumps to boost pressure and meet the high-pressure demands of fire suppression systems. Suitable for forest firefighting and emergency rescue operations, this product can be paired with fire trucks to rapidly establish long-distance water supply lines.
