    Marine120 Kw High Head Sand Gravel Pump For Dredging River, Mining


    Product Introduction


    D, G, GH series pumps are horizontal, single pump casing centrifugal pump. 2, using a special clamp to clamp the pump body and pump cover, the pump outlet direction can be installed at any position of 360 degrees Easy to use. 3, the bearing assembly of the pump adopts a cylindrical structure, which is convenient for adjusting the gap between the impeller and the pump body, and can be completely removed during maintenance. The bearing is greased and lubricated.4, the shaft seal form of the pump has packing seal, and the impeller 6 is used. The transmission mode mainly includes V-type V-belt drive, flexible coupling drive, gear reducer drive, variable frequency drive, thyristor Speed, etc. 7, the material of the over-current component is made of high-hardness wear-resistant alloy cast iron. 8, using a variety of speeds and a variety of variants, so that the pump operates under the best conditions, GH pump is a high lift pump. It is mainly used for continuous conveying of strong abrasive materials that cannot be transported due to the large size of the slurry. Suitable for dredging, sifting gravel, dredging rivers, mining and metal smelting slag conveying.

    Structure Features:


    1. This series of gravel pumps is a centrifugal pump with horizontal and single pump shell structure. It is also a kind of slurry pump in a broad sense.

    2. The pump body and the pump cover are clamped by a special clamp. The discharge direction of the pump can be at any position of 360 degrees, which is convenient to install and use.

    3. The bearing assembly of the gravel pump adopts a cylindrical structure, which is convenient for adjusting the gap between the impeller and the pump body, and can be completely removed during maintenance.

    4. The bearing is greased.

    5. There are three types of shaft seals for gravel pumps: packing seals, impeller seals, and mechanical seals.

    6. The gravel pump has a wide flow path, good cavitation performance, high efficiency and wear resistance.

    7. Transmission modes mainly include: V-type V-belt drive, flexible coupling drive, gear reducer drive, fluid coupling drive, thyristor speed control, etc.

    8, over-current parts material: nickel-containing high chromium wear-resistant alloy.

    9, using a variety of speeds and a variety of variants, so that the pump operates under optimal conditions.

    10, long service life, high operating efficiency, can meet a variety of poor transport conditions.
