Hydraulic Motor Submersible Sand Dredge Pump with Two Excavator

Sundream submersible dredge pumps are extra heavy duty submersible slurry pumps designed for pumping sand, gravel, and rock, particularly in the mining and dredging industry. These pumps function as both a pump and an excavator, offering a unique combination of efficiency and functionality. The design integrates a patented Sundream agitator directly on the pump shaft, along with a closed impeller, large open passages for easy passage of solids, a heavy-duty shaft and bearing configuration, special seals working in an oil bath, and 4, 6, 8 or 10 pole custom-built electric motors. The impeller, wear plates, and agitator are manufactured using cast chrome iron (24 to 28%). These pumps are ideal for handling abrasive materials and can be customized according to client requirements. They are known for their durability, reliability, and performance in harsh environments. Key Features: - Submersible operation without suction head influence. - No need for an auxiliary vacuum pump, saving investment. - Quiet operation, maintaining a noise-free work environment. - Integrated agitator eliminates the need for additional stirring devices. - No requirement for a pump house, making them highly convenient. - Direct operation on the surface of slurry for higher efficiency. Applications: - Transfer of wastewater, effluent, and solids-laden water in: - Water treatment - Building services - Sumps and basements - Mining - Civil construction - Industry - Municipal - Processing Performance Curve: [Image of performance curve] Sectional Drawing: [Images of sectional drawings] Product Specifications Table: | NO. | Model | Outlet Dia (mm) | Flow (m³/H) | Head (m) | Power (kW) | Speed (rpm) | Max Particle Size (mm) | |-----|--------------|------------------|-------------|----------|------------|-------------|------------------------| | 1 | QSZ30-15-4 | 80 | 30 | 15 | 4 | 1460 | 13 | | 2 | QSZ30-20-5.5 | 80 | 30 | 20 | 5.5 | 1460 | 10 | | 3 | QSZ50-15-5.5 | 100 | 50 | 15 | 5.5 | 1460 | 15 | | 4 | QSZ30-30-7.5 | 80 | 30 | 30 | 7.5 | 1460 | 13 | | 5 | QSZ50-21-11 | 80 | 50 | 21 | 11 | 1460 | 21 | | 6 | QSZ50-26-11 | 80 | 50 | 26 | 11 | 1460 | 13 | | 7 | QSZ100-18-11 | 100 | 100 | 18 | 11 | 1460 | 21 | | 8 | QSZ25-40-15 | 80 | 25 | 40 | 15 | 1460 | 13 | | 9 | QSZ50-35-15 | 80 | 50 | 35 | 15 | 1460 | 13 | | 10 | QSZ60-30-15 | 100 | 60 | 30 | 15 | 1460 | 13 | | 11 | QSZ75-25-15 | 100 | 75 | 25 | 15 | 1460 | 13 | | 12 | QSZ150-15-15 | 100 | 150 | 15 | 15 | 1460 | 21 | | 13 | QSZ75-35-22 | 100 | 75 | 35 | 22 | 1460 | 13 | | 14 | QSZ75-45-22 | 100 | 75 | 45 | 22-30 | 1460 | 13 | | 15 | QSZ100-25-22 | 100 | 100 | 25 | 22 | 1460 | 14 | | 16 | QSZ150-22-22 | 150 | 150 | 22 | 22 | 1460 | 32 | | 17 | QSZ200-15-22 | 150 | 200 | 15 | 22 | 1460 | 45 | | 18 | QSZ100-35-30 | 150 | 100 | 35 | 30 | 1460 | 21 | | 19 | QSZ140-30-30 | 100 | 140 | 30 | 30 | 1460 | 21 | | 20 | QSZ200-25-30 | 150 | 200 | 25 | 30 | 1460 | 25 | | 21 | QSZ250-20-30 | 150 | 250 | 20 | 30 | 1460 | 25 | | 22 | QSZ100-45-37 | 150 | 100 | 45 | 37 | 1460 | 21 | | 23 | QSZ100-50-37 | 150 | 100 | 50 | 37 | 1460 | 13 | | 24 | QSZ300-20-37 | 150 | 300 | 20 | 37 | 1460 | 28 | | 25 | QSZ100-60-45 | 100 | 100 | 60 | 45 | 1460 | 13 | | 26 | QSZ200-30-45 | 150 | 200 | 30 | 45 | 1460 | 25 | | 27 | QSZ150-45-55 | 150 | 150 | 45 | 55 | 1460 | 21 | | 28 | QSZ250-35-55 | 150 | 250 | 35 | 55 | 1460 | 36 | | 29 | QSZ300-30-55 | 150 | 300 | 30 | 55 | 1460 | 36 | | 30 | QSZ600-15-55 | 250 | 600 | 15 | 55 | 1460 | 32 | | 31 | QSZ150-55-75 | 150 | 150 | 55 | 75 | 1460 | 15 | | 32 | QSZ150-60-75 | 150 | 150 | 60 | 75 | 1460 | 15 | | 33 | QSZ200-45-75 | 150 | 200 | 45 | 75 | 1460 | 18 | | 34 | QSZ200-55-75 | 150 | 200 | 55 | 75 | 1460 | 18 | | 35 | QSZ350-35-75 | 200 | 350 | 35 | 75 | 1460 | 29 | | 36 | QSZ400-25-75 | 200 | 400 | 25 | 75 | 1460 | 29 | | 37 | QSZ200-60-90 | 150 | 200 | 60 | 90 | 1460 | 14 | | 38 | QSZ250-55-90 | 150 | 250 | 55 | 90 | 1460 | 14 | | 39 | QSZ300-45-90 | 150 | 300 | 45 | 90 | 1460 | 25 | | 40 | QSZ300-50-90 | 150 | 300 | 50 | 90 | 1460 | 25 | | 41 | QSZ400-40-90 | 200 | 400 | 40 | 90 | 1460 | 25 | | 42 | QSZ500-25-90 | 200 | 500 | 25 | 90 | 1460 | 25 | | 43 | QSZ450-30-90 | 200 | 450 | 30 | 90 | 1460 | 25 | | 44 | QSZ250-60-110| 150 | 250 | 60 | 110 | 1460 | 18 | | 45 | QSZ300-60-110| 150 | 300 | 60 | 110 | 1460 | 18 | | 46 | QSZ400-50-110| 200 | 400 | 50 | 110 | 1460 | 28 | | 47 | QSZ500-35-110| 200 | 500 | 35 | 110 | 1460 | 32 | | 48 | QSZ600-30-110| 250 | 600 | 30 | 110 | 1460 | 35 | | 49 | QSZ800-25-110| 300 | 800 | 25 | 110 | 1460 | 50 | | 50 | QSZ1000-18-110| 300 | 1000 | 18 | 110 | 1460 | 50 | | 51 | QSZ780-26-110| 300 | 780 | 26 | 110 | 1460 | 50 | | 52 | QSZ400-60-132| 200 | 400 | 60 | 132 | 1460 | 28 | | 53 | QSZ500-45-132| 200 | 500 | 45 | 132 | 1460 | 28 | | 54 | QSZ500-55-132| 200 | 500 | 55 | 132 | 1460 | 28 | | 55 | QSZ800-35-132| 300 | 800 | 35 | 132 | 1460 | 42 | | 56 | QSZ1000-22-132| 300 | 1000 | 22 | 132 | 1460 | 50 | | 57 | QSZ1250-15-132| 300 | 1250 | 15 | 132 | 1460 | 56 | | 58 | QSZ600-50-160| 200 | 600 | 50 | 160 | 1460 | 28 | | 59 | QSZ650-52-160| 200 | 650 | 52 | 160 | 1460 | 28 | | 60 | QSZ1250-25-160| 350 | 1250 | 25 | 160 | 1460 | 56 | | 61 | QSZ1000-30-160| 300 | 1000 | 30 | 160 | 1460 | 53 | | 62 | QSZ1750-15-185| 350 | 1750 | 15 | 185 | 1460 | 56 | | 63 | QSZ600-55-200| 250 | 600 | 55 | 200 | 1460 | 28 | | 64 | QSZ800-45-200| 300 | 800 | 45 | 200 | 1460 | 42 | | 65 | QSZ1000-40-200| 300 | 1000 | 40 | 200 | 1460 | 42 | | 66 | QSZ1500-20-200| 350 | 1500 | 20 | 200 | 1460 | 56 | | 67 | QSZ2000-20-200| 400 | 2000 | 20 | 200 | 1460 | 56 | | 68 | QSZ800-55-220| 300 | 800 | 55 | 220 | 1460 | 38 | | 69 | QSZ1250-35-220| 350 | 1250 | 35 | 220 | 1460 | 45 | | 70 | QSZ1000-50-250| 300 | 1000 | 50 | 250 | 1460 | 45 | | 71 | QSZ1500-35-250| 350 | 1500 | 35 | 250 | 1460 | 50 | | 72 | QSZ1750-30-250| 350 | 1750 | 30 | 250 | 1460 | 55 | | 73 | QSZ1500-40-280| 350 | 1500 | 40 | 280 | 1460 | 50 | | 74 | QSZ1750-40-315| 350 | 1750 | 40 | 315 | 1460 | 55 | | 75 | QSZ2000-35-315| 400 | 2000 | 35 | 315 | 1460 | 60 | For more information about these pumps, please contact us directly via email or phone.
