Product Description

                                                Product introduction



LQDLFD pumps are stainless steel light vertical low-noise multi-stage centrifugal pumps .With ducted structures,they may be directly installed in horizontal pipeline systems to get compact structures and save space.Each of them comprises a low-niose motor,and a pnmp head.The water-cooled loe-noise motors is a new product developed by us after long-time research to meet the environmental protection requirement of the new century for noise.It is a new generation environment-friendly and energy-saving product characterized in that the motor is not cooled by a fan;the water-cooled mode is used and the cooling effect is great;the motor has great overload capacity but low noise and generates no noise interference in human settlements.
                                                                Applications
Water supply:filtering,conveying,zoning based water supply,and main pipe pressurization of water plants,and pressurization of high-rise buildings
Industrial pressurization:process water systems,cleaning system,high-pressure flushing systems,and fire fighting systems.
Conveying of industrial liquids:cooling and air-conditioning systems,boiler water supply and condensation systems,supporting facilities of machines,acides,and alkalis.
Water treatment:ultrifiltration systems,reverse osmosis systems,distillation systems,separators,and swimming pools
Irrigation:farm irrigation,sprinkling irrigation,and drip irrigation
                                       Operating conditions
Thin,clean,non-inflammable,non-explosive liquids containing neither solid particals nor fibers.
Liquid temperature:Room temperature type:-15ºC to +70ºC
                                         Hot water type:+70ºC to +120ºC
Ambient temperature:+40ºC at most
Altitude:100m(this altitude would be the best)
                                           Pumps
The LQDLFD pumps are stainless steel light vertical multi-stage centrifugal pumps characterized by high efficiency,low noise,compact structure,beautiful appearence,small volum,light weight,convenient operation and maintenance,reliable sealing performance,no secondary pollution for the conveyed liquids,slight corrosion resistance,etc. They may be provided with intelligent protectors as required to provide effective protection for their running without water,open-phase phenomenon,and overload.
