1. Material Inspection: Pump head and component materials: Pump casing made of corrosion-resistant treated aluminum alloy; impeller constructed from wear-resistant, corrosion-resistant aluminum alloy; other parts fabricated from wear-resistant, corrosion-resistant materials such as aluminum alloy, stainless steel, and copper. ▲2. The pump assembly consists of a single-stage centrifugal pump body integrated with a four-stroke single-cylinder air-cooled gasoline engine. It can be operated either handheld or backpack-mounted. The pump body and engine feature a direct-connect integrated linkage. ▲3. Engine nameplate specifies power ≥2HP/7000rpm, displacement ≥48cc (ml), built-in fuel tank capacity ≥1.3L, and transistor ignition system. 4. Starting Method: Self-retracting recoil starter or push-button electric start. 5. Portable design allows for hand-carrying or backpacking. The pump frame is integrated with the pump body. 6. Inlet diameter: 2“ BSP male thread (50mm); Outlet diameter: 1.5” BSP male thread (40mm). Includes 3/8“, 1/4”, and fan-shaped three-hole integrated spray guns. 7. Positions posing safety hazards to operators must display prominent warning and caution labels. 8. Pump units support direct series, parallel, or series-parallel configurations. ▲9. Net weight: 15kg. ▲10. Priming method: Manual vacuum diaphragm priming. Priming pump integrated with pump body. Diaphragm diameter ≥100mm, thickness ≥2.5mm. Entire assembly (excluding diaphragm) constructed of synthetic resin. ▲11. Equipment dimensions: ≤395×320×420mm 12. Sealing test: The pump shall undergo sealing tests per Clause 10.5 of GB 6245-2006. No leakage, sweating, or defects shall occur on the pump body or components during testing. 13. Hydraulic pressure test: The pump shall undergo strength testing at 0.5MPa for 40 hours. After testing, the pump shall start normally with all parameters within specifications. ▲14. Continuous Operation Performance: After filling with oil, full-load operation time ≥90 minutes; with the outlet closed, the pump should operate at high speed for over 30 minutes. 15. Lateral and Longitudinal Tilt Test: The pump assembly should function normally under lateral and longitudinal tilts of 15°. 16. Performance Testing: Condition 1: Pressure 0.3MPa, Flow ≥2.7L/s; Pressure 0.6MPa, Flow ≥2.4L/s 17. Maximum Pressure (Zero Flow) ≥1.0MPa ▲18. Maximum Head ≥102m ▲19.

Priming Vacuum Seal Performance: ≤0.8kPa ▲26. Ear-Level Noise: ≤97dB(A)

High-lift water pumps are pressure-boosting devices specifically designed for forest firefighting water supply scenarios. Their 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. This product is suitable for forest firefighting and emergency rescue operations, and can be paired with fire trucks to rapidly establish long-distance water supply lines.
