LISG single-stage single-suction vertical centrifugal pumps are new generation energy-saving products newly developed by us.They are new upgraded products designed and produced based on the performance parameters of the LIS centrifugal pumps and an advanced hydraulic model and strictly in line with relevant requiremnets of the national standard ISO2858 and the national standard JB/T53058-93.They are applicable to the conveying of noncorrosive frozen water and hot water in fields such as air-conditioing,heating,sanitary water,water treatment,cooling and refrigeration systems,liquid circulation and water supply,pressurization,and irrigation.
(Please refer to the relevant annex for the design maximum operating pressures of some of the pumps)
Structure
LISG pumps:they are single-stage single-suction vertical centrifugal pumps.The inlet and outlet of each one is on a single straight line and has the same caliber.
Model/specification-caliber:20~300(mm)
The pumps with a caliber of 20mm to 300mm are direct-coupled with motors;the pump bearings are completely concentric and realize direct power transmission; they have the advantages of low noise,small vibration,steady operation,and small floor area.
Maximum operating pressure:1.6Mpa.The medium is clean water with a temperature not higher than 80ºC,or liquids with physical and chemical properties similar to that of clean water.
Body,cover,and impeller:cast iron(HT200)
Pump bearing:2Cr13,45#
Mechanical seal:rubber bellows are used for sealing;the rotating ring and the stationary ring are made of a hard alloy.
(or other applicable materials may be used according to requirements of the mediums conveyed by users)
