12 Inch Centrifugal Sand Pump High Head Gravel Sand Pump Sand Pumping Low-Speed Sand Suction Pump

12 Inch Centrifugal Sand Pump High Head Gravel Sand Pump Sand Pumping Low-Speed Sand Suction Pump

Low-Speed Sand Suction Pump is designed for continuously handling the most difficult higher abrasive slurries which contain too big solids. The gravel sand 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 a heavy flow, easy installation, and operation, good performance of NPSH, and abrasion resistance.
Low-Speed Sand Suction Pump is designed for continuously handling the most difficult higher abrasive slurries which contain too big solids. The big particle gravel sand pump is cast as a single pump casing structure with a smooth over-current channel. The overflow part is made of hard nickel and high chromium wear-resistant alloy. The outlet direction of the gravel pump can be adjusted according to the requested direction. The gravel sand 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 a heavy flow, easy installation, and operation, good performance of NPSH, and abrasion resistance.



 

1. The gravel pump is a horizontal, single-pump casing structure centrifugal pump.
2. Use a special clamp clamping pump body and pump cover, the pump outlet can be adjusted in any direction of 360 degrees, easy to install and use.
3. The bearing components with cylindrical structure, easy to adjust the gap between the impeller and the pump body to keep a long working life.
4. Bearing with grease lubrication.
5. Gravel pump has three kinds of shaft seal including packing seal, vice impeller seal, and mechanical seal.

The large particle Low-Speed Sand Suction Pump, also known as the large particle sand pump and gravel pump, is modified by the ocean pumping industry based on similar products in Australia. It is mainly used in a working environment with high flow requirements and is suitable for pumping pebbles and large particles. Granular mud, domestic garbage, medium-coarse sand, and other media. Large-particle Low-Speed Sand Suction Pumps began to be used in industrial and mining enterprises and later developed into engineering projects such as river dredging, sand pumping, and embankment consolidation. The unique three-blade impeller of Low-Speed Sand Suction Pump has a wide flow path, a thickened pump casing impeller design, and the selection of high chromium alloy materials for the flow parts, which greatly enhances the service life and ensures long-term stable and efficient operation in sand pumping operations, The application range is very wide. Low-Speed Sand Suction Pumps are not suitable for all working conditions. The disadvantages of this type of pump are first that there are fewer blades and the outer diameter of the impeller is relatively small. Therefore, the shaft power is relatively lower than that of marine sand pumps or high-lift slurry pumps. Some, the result is that under the same power ratio, the output will be lower than the other two pump types, so customers need to consider this factor in the selection process.

In June 2020, a user in Cameroon, an African country, contacted the foreign trade manager of OCEAN PUMP and put forward the following construction requirements:

1. For river sand pumping, the high chrome gravel pump made in Guangdong was previously used. The effect is good but the wear is faster. I hope to use the high chrome gravel pump of wear-resistant alloy;
2. There are many impurities and pebbles in the river, and I hope to choose a pump with a wider flow channel;
3. The customer has a 550kw/1500rpm diesel engine, the flywheel size is provided, and the gearbox needs to be matched according to the power and speed;
4. At the same time, ultra-high molecular weight wear-resistant polyethylene sand discharge pipes and polyethylene floating bodies are required.

The requirements of the customer are relatively clear. The selection engineer team of OCEAN PUMP selected the pump type after simple negotiation and selected the ZS450 type Low-Speed Sand Suction Pump and the Hangzhou developed 600 types 3.5:1 gearbox. Chai 8170 type 18# flywheel is consistent and easy to match successfully, according to the calculation of pipeline head loss, matched with polyethylene pipe and floating body for large particle high chrome gravel pump. Later, the customer raised the issue of the public base, the designer of OCEAN PUMP completed the drawing plan, and the customer finalized the purchase contract.
