Syria customer purchased Submersible pump stainless steel with head = 500 m and flow rate = 50 m3/h
Actually I know that we got a similar order in the last year and we provided pumps(flow rate=70m3/h, head=500m) to customer in China. And feedback was good.
According to Syria customer request, we recommend pump 250QJH50-500-200KW.
Because there is a ready-made molds for this pump, there is no need to prepare new molds, the price is lowest. Meanwhile, because we have ready-made parts, the production time will be shorter.
There is the specification of this pump in the below, please check them. It can be used in the well with an inner diameter of 300mm or more.
Please note that because the pump head is too high, we will install the support frame on the pump body to protect the shaft.
At the same time, we have replaced the motor coil, cable and other accessories, so that the max. water temperature can be 80degree.
If you need a temperature sensor, we can also add it.
In a word, we think this pump model is the best choose to you.
If you have any questions about quotation or pump, please contact me freely.
Questions from Syrian customers about the Submersible stainless steel pump:
The offer is good but i need to ask you about the things.
First, we have sand in water about 50 gr/m3 and the sulfide percent is 0.012.
Second, the technical offer dose not have a filter on suction of the pump and the water is not a clean water. it has sands and sulfide.I am waiting for you response as soon as possible.
Shenlong Answer:
For well pumps, it is normal to have sand in the well water. And just now we talked about it with engineer, 50 gr/m3 sand in the water and 1.2% sulfide is ok for our pump.
There is a stainless steel filter on suction of the pump. And you could find it in the drawing. Please check attached picture.It can filter out large particles of impurities.
