Chilean customer purchases 120KW Dewatering Submersible Pump for drainage of mines
Can the pump be operated below 77.5 meters Head. As the performance curve is not showing below 77.5 meters head.
The head range of this pump is 75-93meters, the pump will not overload when working in this range.
We have solid particles up to 60 mm in the slurry. Are you providing suitable filters to avoid these large size particles.
We will provide you suitable filters to avoid large size particls, and it’s for free.
There is the data specification with curve of WQD300-70-120kw in the below.
As showed in the curve, the shaft power will be 88kw when the pump is working at the rated point, while the pump medium density is large, in order to avoid overcurrent of the motor, we recommend the motor of 120KW.
