ZDY self-balancing multi-stage pump Overview: ZDY self-balancing multi-stage pumps overview is designed 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, efficient use of state recommended hydraulic model of energy-saving products, according to API610 standard and efficient research and development of 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 loss, so ZDY self-balancing multi-stage pump Overview pump efficiency 5-14% higher than in the same category multistage pumps, while balancing device failure due to solve resulting balance disc and balance disc or rotor wear seat killed and other failures, 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, ZDY self-balancing multi-stage pump Overview sealing system designed in accordance with API682 second edition. ZDY self-balancing multi-stage pump parameters: maximum flow Qmax = 850m3 / h; maximum head Hmax = 1800m maximum speed nmax = 2950rpm operating temperature t≤210 ℃ ZDY self-balancing multi-stage pump Uses: 1. boilers in industrial equipment water supply systems and condensate transportation 2. In petroleum, petrochemical, coal chemical industry, chemical industry and media delivery 3. 4. oilfield chemical process water, mine drainage Company Name: Grace Changsha Pump Manufacturing Co., Ltd.
