Wide Channel Nonblckage Sand Gravel Dredging Pump with Powerful Suction
The Sand Gravel Dredging 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.

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.
6. Wide flow channel, good cavitation performance, high efficiency, and abrasion resistance.
7. Transmission methods are V-shaped V-belt driven, flexible coupling driven, gearbox transmission, hydraulic coupling driven, thyristor speed control speed, and so on.
8. Over-flow components Material: nickel-containing high-chromium wear-resistant alloy.
9. Using a variety of speeds and variants, make the pump run in the best conditions.
10. Long working life and high operating efficiency can meet a variety of bad working conditions.
Applicable to: sand dredge pumping, dredge river, mining, and transport metal smelting.Flow range: 36-3800 m 3 / h Head range: 3.5-80 m. Maximum through particle size: 254 mm.Maximum efficiency: 72% Cavitation allowance: 2-8 NPSH (r).
The large particle Sand Gravel Dredging 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 Sand Gravel Dredging 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 the Sand Gravel Dredging 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. Sand Gravel Dredging 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:
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 Sand Gravel Dredging 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.
Performance parameters of OCEAN brand large particle Sand Gravel Dredging Pump:
Model: ZS450 large particle Sand Gravel Dredging Pump
Flow rate: 2700 cubic meters per hour
Head: 26 meters
Supporting generator set: 550kw/1500rpm
Supporting gearbox: 600 types, Model: 3.5:1
After detailed communication, the customer approved the sand pumping equipment and the supporting equipment and signed the purchase contract in September 2020. OCEAN PUMP actively arranged production and procurement, and the sand pump unit was ready within 20 working days.
The customer attached great importance to product performance, so entrust a comprehensive test on the high-head sand pump to the SGS testing agency. The test content was as follows.
