DL Series Vertical Multistage Centrifugal Pumps
Product Name: DL series Vertical Multistage Centrifugal PumpsProduct Category: Multistage PumpsI. Product Overview:DL vertical multi-stage centrifugal pumps are of a vertical multistage segmental structure. A hydraulic model of an efficient and energy-saving IS type pump,Website:, which is recommended by our country, is used. The screw handle water inlet section, the middle section and the water outlet section are integrally connected. An impeller and a guide blade are arranged at each stage. The problem of axial force is solved through a hydraulic balancing method, residual axial force is borne by ball shaft bearings, and grease lubrication is used. The shaft seal adopts the soft packing or mechanical seal. Products implement the JB/T2727-93 Vertical Multistage Centrifugal Pump type and Basic Parameters standard and are mainly used for suctioning and diluted, cleaned, non-corrosive and non-explosive clean water and liquid without solid particles or fibers and with the physicochemical property similar to that of water.Products of our company all designed and optimized through computers; the company has strong technical force, abundant production experience and perfect testing means, so that stability and reliability of products are guaranteed.II. Scope of Application:Pumps are widely used for fire protection and living water supply for high-rise buildings as well as circulating and cooling water transportation for air conditioning units.III. Product Characteristics:1. Advanced hydraulic model: high efficiency and wide performance range.2. Novel structure and reliable running: balance drums are omitted, hydraulic balancing is used for axial force, the problems that balance drums are easy to rust, scuff and abrade are solved thoroughly, and it is guaranteed that running is more reliable.3. Less running and maintenance costs: high-quality mechanical seal is used and is wear-resistant, free of leakage, long in service life and low in failure rate and lower in operation and maintenance cost.4. Stable operation and low noise: the low-speed motor is used, so that the pump runs smoothly and lower in noise.5. Vertical structure occupies small area.IV. Technical Parameters:Flow rate: 4.2-504m3/h;Head: 24-240m;Power: 1.5-450kw;Rotation speed 1480r/min;Aperture: phi 40-phi 250;Temperature range: 0-/+90 DEG C;Work pressure: ≤2.4MpaV.
