G (or GH) type gravel pump is a series of products introduced from Australian companies. It is mainly used for the continuous transportation of highly abrasive materials that cannot be conveyed by general slurry pumps because the particles are too large. It is suitable for dredging by dredger, dredging of river channels, transportation of mining and metal smelting blasting slag, etc. Among them, the GH type is a high-lift gravel pump.
The pump has a single casing structure connected by a cassette with a wide overflow channel. Its overflow parts are made of wear-resistant materials such as hard nickel and high chromium. The outlet direction of the pump can be in any position of 360°, which has the advantages of easy installation and use, good cavitation performance and anti-abrasion.
The main models are:
6/4d-g ,8/6e-g ,10/8f-g ,10/8s-gh ,12/10g-g ,14/12g-g，18/16g-g。
Product Overview. G-type sand and gravel slurry pump: This product is a cantilever and centrifugal pump. It adopts a single pump casing structure connected by cassette, which has good wear resistance, corrosion resistance and high reliability. The product structure is reasonable, the operation is reliable, and the service life is long. It is especially suitable for the continuous transportation of highly abrasive materials that cannot be conveyed by general slurry pumps due to the large particles.
Benefits: l Long service life of wearing parts.
l High efficiency and low energy consumption.
l Easy to maintain.
l Low operating costs.
l High reliability.
Fields of application. It is mainly used for dredging, dredging of river channels, mining and transportation of metal smelting blasting slag, etc.
Structural features: l It adopts a single pump casing structure connected by cassette, the overflow channel is spacious, and the lining is cemented carbide, which has good wear resistance, corrosion resistance and high reliability.
l Barrel structure bearing assembly, using high-capacity bearing design, bearing grease lubrication, oil lubrication to adapt to different working conditions.
l The gap between the impeller and the guard plate can be adjusted to ensure the efficient operation of the pump.
l The shaft seal adopts packing seal, impeller seal and cartridge mechanical seal to adapt to different working conditions.
l The pump and the drive can be driven by direct drive, V-belt drive, fluid coupling drive and reducer drive.
l The outlet direction of the pump can be rotated and installed at any angle to adapt to different on-site installation conditions.
