ZDF-type self-balance multistage centrifugal pump corrosion Overview: ZDF-type self-balance multistage centrifugal pump corrosion is to meet user needs, accelerate the development of high-pressure multi-stage pump technology, the use of similar foreign products, advanced technology combined with our years of experience in the design, using state recommended hydraulic model of energy-efficient products, according to API610 standard research and development of efficient high-pressure multi-stage centrifugal pumps; living technology leadership position in the industry. Efficient district wide, wide range of performance, cavitation performance, safety and smooth operation, low noise, less wearing parts, and easy installation and maintenance. Greatly improved reliability, uptime is more than three times the normal pump, user maintenance costs greatly reduced, thereby reducing the life cycle cost of the pump. Segmental centrifugal high-pressure self-balancing will form the structure of the traditional multi-stage centrifugal pumps of the innovative, multi-stage centrifugal canceled axial force balance mechanism ,, is the use of the balance disc or drum balanced structure D, DG-type multi-stage Centrifugal best alternatives. Because no balancing device, ie no loss of balance disc friction disc nor balanced reflux losses, so the pump efficiency 5-14% higher than in the same category multistage pumps, while thoroughly address the balance and lead to device failure balance disc and balance disc seat wear or killed by other rotor failure, greatly extend the life of the pump. Years of operation proved that the product performance reached the international advanced level of similar products. For transporting solid particles less than 2% (particle size less than 1mm), the dielectric solids concentration of less than 5% wt. With the use of water or physical and chemical properties similar to water temperature ≤105 ℃ other liquids or liquids. Also by changing the pump material (or pump flow components of the material), seal the form and increase the cooling system for transporting temperature ≤210 ℃ hot water, oil, corrosive or abrasive media and so on. Materials are HT200, QT600,304,304L, 316L, 317L, 904L, CD4 and other materials available for users to choose. Compliance with API610 8th / API610 9th / API610 10th standard design, ZDF-type self-balance multistage centrifugal pump corrosion sealing system designed in accordance with API682 second edition. ZDF-type self-balance multistage centrifugal decay parameters: maximum flow Qmax = 850m3 / h; maximum head Hmax = 1800m maximum speed nmax = 2950rpm operating temperature t≤210 ℃ ZDF-type self-balance multistage centrifugal pump corrosion purposes: 1. In the petroleum, petrochemical, coal chemical industry, chemical industry and media delivery 2. descaling equipment pressure water delivery 3. 4. oilfield chemical process water, mine drainage 5. 6. brine solution mining output compressor, de-oxidation Paper machines, shelling machines and other equipment water delivery company name: Grace Changsha Pump Manufacturing Co., Ltd.
