1. Appearance Quality: The outer surface of all castings shall be free from visible defects such as slag inclusions, gas bubbles, or sand holes. 2. Pump Assembly Composition: The pump assembly consists of a five-stage centrifugal pump and a four-stroke air-cooled twin-cylinder gasoline engine. 3. Seal Test: The pump shall undergo seal testing per Clause 10.5 of GB 6245-2006. During testing, the pump body and components shall not exhibit leakage, sweating, or similar defects. 4. Water Pump Strength Test: The water pump shall undergo strength testing at 1.1 MPa for 40 hours. Continuous testing is not required; each test segment shall last no less than 6 hours. After 40 hours, the pump shall start normally with all parameters within specifications. 5. Water-inlet vacuum seal performance (kPa): ≤0.8 6. Maximum water-inlet vacuum (kPa): ≥85 7. Maximum vacuum test: With a suction pipe length ≥9 meters, manually evacuate using a diaphragm pump to achieve maximum vacuum. Maintain this vacuum for 3 minutes with no change. 8. Engine power ≥20kW, built-in fuel tank ≥5L. 9. Starting method: Manual pull-start or electric start. 10. Transmission performance: Oil-free, maintenance-free synchronous transmission equipped with polyurethane or equivalent quality synchronous toothed belt drive. Engine includes charging function. 11. Priming method: Mechanical priming. 12. Maximum suction lift: ≥6m 13. Maximum discharge range: ≥30m 14. Maximum pressure: ≥3.5 MPa 15. Maximum head: ≥300 m 16. Rated flow rate: ≥300 L/min 17. Net weight: ≤95 kg 18. Inlet diameter: 50 ± 2 mm; Outlet diameter: 40 ± 2 mm 19. Maximum gearbox outer diameter: ≥180 mm 20. 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

Didelio aukščio vandens siurbliai - tai slėgį didinantys įrenginiai, specialiai sukurti miško gaisrų gesinimo vandens tiekimo scenarijams. Pagrindinė jų funkcija - užtikrinti greitą ir stabilų gaisro gesinimo vandens tiekimą į įvykio vietą, kai vandens šaltinio slėgis yra nepakankamas, naudojant daugiapakopius išcentrinius siurblius, kurie padidina slėgį ir atitinka gaisro gesinimo sistemų aukšto slėgio reikalavimus. Šis gaminys tinka miško gaisrų gesinimui ir avarinėms gelbėjimo operacijoms, jis gali būti sujungtas su gaisriniais automobiliais, kad būtų galima greitai nutiesti tolimas vandens tiekimo linijas.

I. Prisitaikymas prie ekstremalios lauko aplinkos II. Pagrindinės avarinio gaisro gesinimo savybės III. Ilgaamžiškumas, lengva priežiūra ir saugumo užtikrinimas IV. Atitiktis ir praktiniai papildomi privalumai
