1.As soon as amphibious dredger is concerned, we will offer you at the price of 580,000 USD (with excavator depends on you )
2.The ex-factory price of the only dredger is 29 0,000 USD (with excavator depends on you )
For your benefits ,we advise you to purchase the second one,because the waterflow you required is 120m3/h,but there are a little bit of loss more or less in the practice.so the real waterflow must be more than 150m3/h at least。We will send you' a picture of this type of our products after a while. We hope that will benefits you the most.
Otherwise ,,We are kindly inform you that our products are well paid for the money and competitive, we have a steady market both home and abroad .
So we hope you will make the decision as soon as possible .
