Pump Unit Configuration: Direct series, parallel, or combined series-parallel configurations are achievable. 21. Operating Environment: Under rated conditions with 15° lateral or longitudinal tilt, continuous operation ≥24h must be maintained with normal pump function. 22. Engine Protection Device: Features automatic shutdown with lubrication protection. 23. Pump Housing Material Tensile Strength: ≥290MPa 24. Pump Configuration: Each pump includes one hose backpack. The backpack fabric is waterproof and tear-resistant, featuring multiple drainage holes at the bottom, side handles, and four rubber pads on the base. Net weight: 2.5kg. Capacity: 90m hose. Equipped with an automatic hose-laying port. Designed for dual-shoulder carrying with 70mm-wide shoulder straps and a 35mm-wide waist belt. 25. Hose Pack Lining Material: Lining made of nylon or equivalent quality material, injection-molded as a single unit. Maximum tensile strength: ≥20N; Maximum load capacity: ≥90kg 27. Hose Pack Fabric Properties After 50 Washes: 27.1 Tensile strength at break: - Warp direction: ≥1900N - Weft direction: ≥1600N 27.2 Tear strength: - Warp direction: ≥270N - Weft direction: ≥260N 27.3 Fabric thermal stability: (260℃±5℃) % ≤0.8

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.
