Horizontal Single Casing Good Performance Of NPSH Gravel Pump 12 / 10 G-G
Product Introduction
1. Horizontal, single pump housing centrifugal pump.
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 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 bearings are greased.
4. The shaft seal form of the pump has packing seal, impeller seal and mechanical seal.
5. The pump flow path is wide, the cavitation performance is good, the efficiency is high, and the wear resistance is improved.
6. Transmission mode mainly includes V-type V-belt drive, flexible coupling drive, gear reducer drive, hydraulic coupling drive, variable frequency drive, thyristor speed control, 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 a variety of conditions. Long service life and high operating efficiency can meet a variety of harsh conveying conditions. 9. 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.
