Sand Gravel Dredging Pump was Delivered to Malawi for Placer Gold Extracting

Sand gravel dredging pump is mainly used for extracting and transporting large particles whose diameter is too big to be pumped by general sand pump machine. The overflow parts of this kind of sand gravel dredging pump are made of hard nickel and high chromium wear resistant alloy. Sand gravel dredging pump can be installed on land or sand dredger, it is suitable for river dredging, sand pumping, mining, tailing conveying, etc.

At present, the sand pumping market is becoming saturated in China, the management and control of mining licenses are strict in various regions. Therefore, many customers begin to focus on the sand pumping market abroad. Mr. Li and his friend carries out construction project in West Africa. There is a local river rich in mineral resources, especially placer gold. Mr. Li and his friend plan to use a sand pumping equipment to extract the placer gold from the river and then screen and process it.
By friend’s recommendation, Mr. Li knew that sand gravel dredging pump produced by OCEAN Pump can extract placer gold, so he visited our factory. OCEAN Pump engineers introduced every kind of sand pump in detail. In communication, we knew that Mr.Li required the sand pump machine to extract big particle gravel, so our engineers recommended sand gravel dredging pump. This kind of sand pump has the features of wide flow path, good pass-ability, no blockage, the gravel pump casing and impeller are thickened, this increases the wear resistance, reduces the frequency of replacing spare parts and improves working efficiency. The sand gravel dredging pump has various models, there are 6 inch, 8 inch, 10 inch, 12 inch according to caliber. The larger the caliber, the better the pass-ability of the sand pump, the larger the flow rate, the more the output. Similarly, the larger the caliber, the greater the power of the motor or diesel engine required. It was the first time for Mr. Li to engage gold mining industry, considering the actual operation, he wanted to use a small sand dredge pump in the early stage, then increase the investment after getting profit.
In combination with the actual requirements of customer, OCEAN Pump engineers chose ZS 150 sand gravel dredging pump. The inlet diameter is 6 inch, outlet diameter is 4 inches, the max.diameter of particle allowed to pass is about 80 mm , the matching power is not large. It is easy to operate. Mr. Li made a list about the matching equipment requirements after learn the structure performance of this sand pump, OCEAN Pump engineers showed detailed matching equipment plan. Customer signed a purchase contract with OCEAN Pump after checking. Then our company arranged production according to the contract and delivered on schedule.
