QDLF series vertical stainless steel multi-stage centrifugal pump

The QDLF series stainless steel multi-stage stamping centrifugal pump has a vertical structure, and the suction and discharge of the pump are arranged horizontally below the pump. The pump is mainly composed of a vertical motor, motor seat, coupling clamp block, pump body (including pump shaft, impeller, guide vane, alloy bearings, etc.), outer cylinder, base, pull rod, etc. The pump rotor is directly driven by the motor through the coupling clamp block. The axial force of the pump is solved by hydraulic balance. This pump is suitable for transporting clean water or liquids with physical and chemical properties similar to water and other liquids. The operating temperature is ≤ 120 ° C.
The main body of QDLF series stainless steel multi-stage stamping centrifugal pump is made of stainless steel plate stamping and welding. Compared with the commonly used cast iron pump in China, it has the advantages of small volume, light weight, high pump efficiency, low noise, small vibration, easy installation, and beautiful appearance. Due to the use of high wear-resistant hard alloy materials for its bearings and shaft seals, it has the characteristics of long service life and low maintenance. It is an energy-saving new product in the 1990s. In addition to being mainly used for boiler water supply, high-rise building water supply, and fire pressure boosting, it can also be used for orchard irrigation, aquaculture, hydraulic flushing, food and pharmaceutical machinery infusion.
Application range of QDLF series vertical stainless steel multi-stage centrifugal pump
The ordinary type of multi-stage stamping centrifugal pump is suitable for liquid transmission, circulation and pressurization of hot and cold clean water and softened water.
The QDLF series multi-stage stamping centrifugal pump stainless steel type is also suitable for slightly alkaline water, mineral water, distilled water, swimming pool water, and other chloride containing liquids, but the allowable temperature of the liquid needs to be reduced.
Cold and hot clean, non flammable and non explosive liquids that do not contain solid particles or fibers;
Liquid temperature: -15 ℃ to+120 ℃
Environmental temperature: maximum+40 ℃
Minimum inlet pressure: Based on the NPSH curve and a minimum safe head of 0.5 meters.
