summary
The stainless steel vertical multi-stage pump is designed based on the advantages of our company's ISG vertical centrifugal pump and DL vertical multi-stage centrifugal pump. The structure adopts a vertical and segmented form, and the suction and discharge ports of the pump are designed in a zigzag shape below, and excellent hydraulic models are used. The axial force of the pump is solved by hydraulic balance method, and the residual axial force is borne by individual ball bearings, resulting in smooth operation, low noise, small footprint, and convenient decoration. The flow part of the vertical multi-stage centrifugal pump is made of stainless steel (304) material, which has a beautiful appearance and is particularly suitable for the parallel use of multiple pumps in high-rise buildings to reduce the power of single pump units and simplify electrical control equipment. Stainless steel vertical multi-stage centrifugal pump is suitable for fire protection, domestic water supply, air conditioning unit circulation, cooling water transportation, etc. in residential buildings, hospitals, hotels, department stores, office buildings, etc. with high and low floors.
characteristic
1. By adopting excellent hydraulic models and manufacturing processes, the performance and service life of the pump are greatly improved.
2. Due to the use of mechanical seals made of hard alloy and fluororubber, the reliability of pump operation and the temperature of the conveying medium can be improved.
3. The overcurrent part of the pump is made of stainless steel plate stamped and welded, making it suitable for mild corrosive media.
4. The overall structure is compact, small in size, light in weight, low in noise, significantly energy-saving, and easy to maintain.
5. The inlet and outlet of the pump are located on the same horizontal line as the pump seat and can be directly used in the pipeline.
6. Using standard motors, users can easily equip motors according to their needs.
7. Intelligent protectors can be equipped according to user needs to effectively protect pumps from dry rotation, phase loss, overload, etc.
Usage conditions
1. Medium temperature: -15 ℃~+120 ℃.
2. Environmental temperature:+40 ℃.
3. Environmental pressure: 10 bar.
4. The import pressure is limited by environmental pressure.
5. When the density or viscosity of the conveying medium is greater than that of water, it is necessary to consider using a high-power motor.
The motor is selected as a fully enclosed, air-cooled two pole standard motor. Protection level: IP55, insulation level: F, standard voltage (50Hz)
