Four-cylinder piston hydraulic diaphragm pump

1. Operating Condition 1: Flow rate is 5.25 L/s at a pressure of 1 MPa Operating Condition 2: Flow rate is 5.2 L/s at a pressure of 2 MPa Operating Condition 3: Flow rate is 2.97 L/s at a pressure of 6 MPa 2. Total weight of the unit: ≤156 kg 3. Starting method: Manual pull start, non-contact inductive control start, remote control start 4. Sealing test: Block the pump inlet, close the outlet valve, and gradually pressurize the pump casing to a pressure of 6.6 MPa (the sum of the maximum working pressure and the maximum allowable positive pressure at the inlet). Maintain this pressure for 5.1 minutes. During the test, no leakage or sweating was observed on the pump body and components. 5. Hydrostatic strength test: Block all openings of the pump's flow-through components, and gradually pressurize the pump casing to a pressure of 2.0 MPa (the sum of the maximum working pressure and the maximum allowable positive pressure at the inlet). Maintain this pressure for 1 min ± 0.2 min. During the test, no deformation or cracks were observed on the pump casing. 6. Self-movement: The pump unit did not experience any self-movement under any of the operating conditions during the test. 7. Head: ≥600m 8. Horizontal conveying distance: ≥4000m 9. Maximum pressure: 8MPa 10. Range: ≥32.6m 11. Suction depth: ≥7m 12. Priming time: ≤7s 13. Starting performance: ≤5s 14. Working pressure: 0.4MPa (13mm nozzle) 15. Cylinder bore x stroke: 80x71 (±5%) 16. Matching power: Rated power: 16.5kW; Rated displacement: 713cc; Rated torque: 45N·m; Twin-cylinder, four-stroke gasoline engine, forced air cooling. The following power/speed engines are optional: 27HP (20kw)/3600rpm; 30HP (22kw)/3600rpm; 35HP (25kw)/3600rpm 17. Engine oil capacity: 1.5L 18. Continuous operation reliability: Continuous uninterrupted operation for 8 hours; the pump outlet pressure did not fall below the specified pressure. The bearing housing surface temperature was 50℃, the temperature rise did not exceed 32℃, the bearing seal was well sealed, and there was no leakage. The engine did not automatically shut down, and the entire machine did not produce water leakage, oil leakage, or other abnormalities. Vibration and noise are within acceptable limits, and fasteners are not loose. 19. Fasteners and self-locking devices: Fasteners and self-locking devices do not loosen due to vibration or other reasons. 20. Operating mechanism and indicator plate: The operating mechanism is light and reliable, and the operating handle has an indicator plate made of corrosion-resistant material; 21. Check valve: Equipped with a check valve to prevent backflow and protect the pump body. 22. Appearance: 7-inch screen display with touch function; features infrared thermal imaging function, equipped with a high-resolution detector: 384×288; uncooled focal plane detector, supporting multiple pseudo-color modes. 23. Mobile device: Equipped with a lockable mobile device for easy movement. 24. If the CO concentration is higher than 400 PPM (400 parts per million) or the O2 concentration is lower than 19.5%, a first-level alarm is triggered, and the green light flashes; if the CO concentration is higher than 800 PPM (800 parts per million) or the O2 concentration is lower than 18%, a second-level alarm is triggered, both the green and red lights flash, and a buzzer sounds. 25. Accessories: One set of suction and return water pipes, one stop valve, one water gun, one toolbox, one wrench, one pair of pliers, one set of special tools, and four rolls of PTFE tape.

1. Conveying corrosive, toxic, flammable, explosive, or sanitary-grade media (requiring leak-free and contamination-free operation); 2. Conveying media containing solid particles or suspended solids (requiring clog-resistant performance); 3. Conveying high-viscosity media (requiring high-resistance conveying capability); 7. Operating under complex conditions (requiring dry-running capability, wear resistance, mobility, or non-electric drive).

1. High head, high flow, low noise, maintenance-free. 5. Equipped with thermal imaging for rapid heat source detection and gas detectors to protect firefighter safety—China's first-to-market innovation.
