12 Inch High Head Slurry Pump Sent to the United States

High head slurry pump is the excellent slurry pump to realize the long distance transportation of solid materials. This kind of sand pump machine had been widely used for conveying tailing, ash, coal and various concentrates of the power plant. OCEAN Pump brand high head slurry pump has the advantages of high efficiency, low investment, energy saving and environmental protection, easy maintenance and so on.
Our U.S. customer contacted us about their problems of slurry pump in April 2017. They are using a cutter suction dredger to get sand from lake and need a long distance transportation. But the current slurry pump equipped in the dredger is not enough to meet the transport requirements. So, they need to add a powerful  high head slurry pump.

Their transport requirements are as following:
  1. The high head slurry pump must relay out the solid of 250m3/hour from first-level slurry pump.
  2. The high head slurry pump inlet : 350mm, outlet: 300mm;
  3. The distance of transport is up to 1600m;
  4. wear-resistant, easy-to-use.
After calculation, we proposed DS300-70 type sand suction pump unit for customer. And supporting cummins marine diesel engine and marine gear box of 600 type. This type of high head slurry pump is equipped with five blades impeller, with advantage of high efficiency and low failure rate. The pump component in contact with the medium is made of high chromium alloy material. And the pump uses double shell structure which features stable, safe, high head discharge distance and very wear resistant. This pump is very suitable for customer’s condition.

ModelDS300-70
Capacity1800 m3/h
Head49m
Rotate Speed830 r/m
Shaft Power294.5 KW
Specifications of the diesel engineCummins  559kw, 1800 r/m
Gear BoxType 600 – 2:1 hydraulic marine gear box
After communication, our customer agreed with the selection and matching of this slurry pump, and placed orders in September 2017. Our factory arranged production and procurement actively, and prepared the goods within 20 working days for engine long delivery time.
At last, our customer arranged their representative come to test the pump unit. The detection contents are as follows :
  1. shape size of the sand dredging pump, flow components material, the actual efficiency of the system, smooth operation, performance curve;
  2. EPAE mission Certificate of diesel engine.
  3. Containerized monitor, the high head slurry pump needs to be firmly fixed to ensure that the long-term sea cargo without damage.
Through this case, Ocean Pump products passed through the world’s most stringent testing which marking our products and supporting forces have been recognized by the developed countries. And that laid a good foundation for the future exporting of our main pump to Europe and America.
OCEAN PUMP is not only manufacturing best quality sand pump and sand dredger products but also providing professional custom design and fabrication service. ODM and OEM are also available. If you have any questions or inquiries,  please contact us at info@sandpumpmachine.com.

Maldives Customers visited our factory for submerged pump dredger

Submerged pump dredger (ZJQ series) is designed and manufactured with optimized hydrodynamics technology for sand suction and silt clearing. This kind of mud dredger equipment is driven by electric motor. The dredger suitable for conveying liquid with solid particles including gravel, cinders and tailing etc. Submersible slurry pump dredger is widely used in metallurgical industry, mining and thermal power plant, etc. It’s wear resistant wet parts are made of hard metal (Chrome alloy). Large diameter shaft and short overhang make up the bearing assembly, with features of long-term bearing life.  In addition, it has the characteristics of high efficiency, energy saving, simple operation and easy management.

Customer checked and studied the submerged pump dredger products carefully.

On August 24, 2017, Maldives Company business representatives came to inspect our company .We received their inquiry at the beginning of August. They want a submersible slurry pump dredger which can suck the sand from the sea. The dredging depth is about 1-3m, delivery distance is about 150 m. What’s more, the sand is fine sand, and they would use the fine sand to cover the island area.

Our technical team designs a suitable dredger body for them. They want a simple dredger which can operate by one people, the generator power only used for the submersible slurry pump. So we chose the chain block instead of hoist. Besides, the dredger body and submersible slurry pump both uses anti-corrosive paint. We also provide them anti-corrosive rope to move the submersible slurry pump dredger. The brand of generator set is Cummins. Our design makes them very satisfied.

We picked them up on our TAI’AN station, then we went to our factory . We had the slurry pumps in stock, they checked the pump first, study the use of pumps. Meanwhile we showed them our other related products such as simple suction dredger, jet suction dredger in store. they had great appreciation for our productivity and quality.
