Product Name: D&DG type Horizontal Multistage Centrifugal PumpsProduct category: Multistage PumpsI. Product Overview:D and DG type pumps are horizontal,Website: , single-suction multistage segmental centrifugal pumps and have the characteristics of high efficiency, high performance broad range, safe and stable running, low noise, long service life, easy installation and maintenance. They are used for transporting other liquids with the physicochemical property similar to that of water. The pumps can also be used for conveying hot water, oils and corrosive or abrasive media by changing materials and sealing forms of the pump passage components and increasing cooling systems. Products implement JB/T1051-93 Multistage Water Centrifugal Pump-type and Basic Parameters standard. Products are all designed and optimized through computers. Our company has strong technical force, abundant production experience and perfect testing means, so that stability and reliability of product quality are guaranteed.II. Scope of Application:The pumps are applicable to industrial and urban water supply & drainage as well as gavrden sprinkling irrigation, fire control pressurization, long-distance water supply, heating and bathroom, and particularly applicable to water supply for small boilers.III. Product Characteristics:1. The hydraulic model is advanced, efficiency is high, and high performance range. 2. Pumps run smoothly at low noise. 3. Shaft seals adopt soft packing seal or mechanical seal. The seal is safe and reliable, the structure is simple, and maintenance is convenient and quick. 4. Shafts are of a totally sealed structure. It is ensured that shafts are in no contact with the media, so that they do not rust and are long in service life.IV. Technical Parameters:Flow rate: 6.3-300m3/h ；Head: 13-650m ；Power: 2.2-400KW ；Rotation speed: 1450-2950r/min ；Diameter: phi 50-phi200 ；Temperature: ≤ 105 DEG C；Working pressure: ≤ 3.0MpaV.
