ZS sand gravel dredge pump is designed for continuously handing the most difficult higher abrasive slurries which contain too big solids. The big particle sand gravel dredge pump is casted as a single pump casing structure with smooth over-current channel .The overflow part is made of hard nickel and high chromium wear resistant alloy. The outlet direction of sand gravel dredge pump could be adjusted according to the request direction. The sand dredge pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging and so on. The advantages of the pump are heavy flow, easy installation and operation, good performance of NPSH and abrasion resistance.
In November 2021, Simon, a customer who has cooperated with Taian Ocean Pump for many years, contacted us and said that he has a new project next year to pump iron sand by the sea. He is going to build a sand pumping dredger by himself, so he wants us to help recommend a pump set. The solution is that this pump could pump iron sand, and it must be durable. The flow capacity is 500 cubic meters per hour. After the discharge distance is about 200 meters, it is loaded into the dump truck and matched with Weichai marine engine. At the same time, necessary accessories must be prepared.
Because Simon is a customer we have worked with, in order to meet his needs and at the same time consider the most cost-effective solution for him, our sales manager recommended our sand gravel dredge pump to Simon, matched with Weichai marine engines and the well-known Hangzhou gearbox .



Simon has always trusted our products, so after receiving our quotation, he discussed with the project manager, and Simon paid us a deposit 2 days later, saying that he would let us ship the products as soon as possible, because he still needed to deliver according to our sand gravel dredge pump size to do sand pumping.
After 12 days of production, the production of the sand gravel dredge pump set was completed. Simon added another 200 meters of sand discharge pipeline and paid the balance, so we immediately contacted the freight forwarder to order the container. Fortunately, the Philippines is very close to China, and we can reach Manila in 16 days. .
After receiving our sand gravel dredge pump set, Simon was very satisfied with the design and appearance of the pump set, and said he would contact us with any questions. This also makes us very proud, because this is the highest trust our customers have in us.
Hopefully Simon’s sand pumping dredger will be finished soon so we can bring in profit with our gravel pump set.
