Dust suppression systems spray water over yards, stockpiles and roads. This order supplied the pumps for one: horizontal pipeline pumps to feed the spray lines, and submersible pumps to lift water from the source.
| Pump | Duty | Motor | Qty |
|---|---|---|---|
| ISW horizontal pipeline pump | 30 to 60 m³/h, 20 m, fresh water | 7.5 kW, 380 V | 3 sets |
| 50WQ submersible pump | 30 to 60 m³/h, 30 m, fresh water | 5.5 kW, 380 V | 5 sets |
A pipeline pump is not self-priming. If the water source is below the pump, use a flooded suction, a foot valve, or a submersible pump to feed it, as this system did.
