Product Description: Zigong Zipump High Head Single Suction ZD type ZDG type ZDF Horizontal Multi-stage Centrifugal PumpBefore consulting or purchasing, users are requested to provide accurate parameters such as flow rate, head, pipe loss, medium specific gravity, motor power, etc.ZD, ZDF type multi-stage centrifugal pumps are used for conveying clean water without solid particles and media with physical and chemical properties similar to clean water. The medium temperature should not exceed 80°C, suitable for mines, power plants, and urban water supply and drainage.Flow range 6~540m³/h, Head range 33~1056mModel ZD type is used for -20~80 degrees Celsius clean water ZDG type is used for -20~150 degrees Celsius clean waterZDF type stainless steel pump is used for -20~150 degrees Celsius particle-free corrosive media, ZDM type is used for clean water containing a small amount of particles or corrosive media.The basic structure of a multi-stage pump consists of an inlet section, outlet section, intermediate section, end cover, impeller, pump body, pump shaft, bearings, sealing ring, stuffing box, and other components.The inlet section, outlet section, and intermediate section are also called the pump casing, which is the main body of the multi-stage pump. It serves to support and fix, and is connected to the bracket that holds the bearings.The pump shaft is connected to the motor via a coupling, transmitting the motor's torque to the impeller, making it the main component for transferring mechanical energy.The stuffing box mainly consists of packing, water seal ring, packing chamber, packing gland, and water seal pipe. The stuffing box's function is to seal the gap between the pump casing and the pump shaft, preventing water inside the pump from leaking out and outside air from entering the pump. It always maintains the vacuum inside the pump!When friction between the pump shaft and packing generates heat, water is directed through the water seal pipe to the water seal ring to cool the packing and ensure the pump operates normally. Therefore, during routine inspections of the pump's operation, special attention should be paid to the stuffing box, and the packing should be replaced if necessary.Common models of multi-stage centrifugal pumps include:ZD6-25x3~12,
ZD12-25x3~12, ZD25-30x3~10, ZD46-30x3~10, 80ZD30x3~10, ZD155-30x2~10,

125ZD25x2~9, ZD46-50x3~12, ZD25-50x3~12, ZD12-50x2~12, 200ZD43x2~9,
ZD280-43x2~9, ZD85-67x2~10, ZD155-67x3~10The ZDLF/QDLF vertical stainless steel multi-stage pump is designed by combining the advantages of the ZISG vertical centrifugal pump and the ZDL vertical multi-stage centrifugal pump. It features a vertical, segmented structure with the suction and discharge ports arranged in a straight line at the bottom, optimizing the hydraulic model. The axial force is balanced hydraulically, and the residual axial force is borne by a ball bearing, ensuring smooth operation, low noise, small footprint, and easy installation. The outer casing of the vertical stainless steel multi-stage centrifugal pump is made of stainless steel, giving it an attractive appearance. It is suitable for parallel use in high-rise buildings to reduce the power requirement per pump unit and simplify electrical control equipment. It is applicable for firefighting, domestic water supply, air conditioning system circulation, and cooling water transport in high and low-rise buildings such as residences, hospitals, hotels, department stores, and office buildings.Medium: Thin, clean, non-flammable, non-explosive liquids without solid particles or fibers, such as mineral water, softened water, pure water, light oil, and other light chemical media. Liquid temperature: Normal temperature type -15°C to+70°C. Hot water type: +70°C to +120°C. Ambient temperature: Up to+40°C. Altitude: Up to 1000m.ZDL vertical multi-stage centrifugal pumps are mainly made of cast iron HT material and are used for non-corrosive clean media similar to clean water. ZDLF/QDLF vertical stainless steel multi-stage centrifugal pumps are mainly made of stainless steel 304 or 316 and can be used for pumping mildly corrosive media.Flow range: 2m³/h~120m³/h: Head range: 8m~200mApplication fields: Water supply: Water plant filtration and transportation, zonal water supply in water plants, main pipe boosting, high-rise building boosting. Industrial boosting: Process water systems, cleaning systems, high-pressure washing systems, firefighting systems. Industrial liquid transportation: Cooling and air conditioning systems, boiler feed water and condensation systems, machine tool matching, acids and alkalis. Water treatment: Ultrafiltration systems, reverse osmosis systems, distillation systems, separators, swimming pools. Irrigation: Farmland irrigation, sprinkler irrigation, drip irrigation.ZDL/ZDLF/QDLF common models:ZDL/ZDLF2-20~
