Requirement:
Electric Model of Submersible Sand dredge pump, 60-80 cubic meters per hour output, 200mm diameters, 300 meters pipeline, final elevation at the end of discharge pipe 6-8 meters.
Calculation and Result:
1.Sand Production: 60-80m?/h, Max. Solid Percentage 70% in weight, Average Solid Percentage In Volume: 25%, total pump capacity: 80/0.25=320m?/h.
2.Considering Sand Mixture Transferring 200mm pipeline, slurry speed ≥3.3 m/s.
3.Pump capacity requires 420 m?/h, slurry speed ≈3.715 m/s.
4.Pipeline To Head Loss: 300 meters calculated to 17m head loss to pump.
5.Final Elevation at the end of discharge pipe 6-8 meters
6.Pump Head: 25m.
7.Pump model: EL200D-B45, capacity range: 276-638m?/h, head: 22.8-30.4m.
8.Pump capacity: 420m?/h，head: 25m, max. Efficiency: 80%. Max. Particle pass: 51mm.
9.Sand Mixture SG≈1.3kg/m?.
10.Shaft Power: N=Q*H*Slurry SG/102/3.6/η*1.2, η=80%, 75KW engine power is suggested.
Pump Selection:
EL200D-B45(42)/75/6 +2ELEX7.5KW Submersible Slurry/Dredge Pump.
(200: 200mm discharge diameters, B: 4 vane to impeller, 45: 450mm Impeller, 42: 420mm Impeller cut for performance match.)
ELEX: Electric Excavator 7.5KW, 2 Sets.
Pump Data:
1.Max. Particle pass 51mm, vanes for impeller: 4, type: closed.
2. Material: Impeller, Volute Liner, Frame Plate Liner Insert, Agitator by High Chrome Alloy A05.
3. Pump Rotating Speed: 980 rpm.
4.8 m Cable.
5.Steel Cover Motor Engine.
6.380V IP68 50HZ.
7.Weight: 2.4t.
